grandis (Arma) Dallas 1851: 96–97. [ Figs 71–74 ]

Original data: “ ♁ ♀ ”; “a. Trenton Falls . Presented by E. Doubleday, Esq. b. –––––.” [syntypes (male and female)]

LECTOTYPE ♀ (designated by Thomas 1992: 27): purple-margined lectotype disc; red-margined type disc; “41. 5. 17 90.”; “E. Doubleday.”; “3. ARMA GRANDIS ”; “a”; “NHMUK 010592478”. Second to fifth right antennomeres, fourth and fifth left antennomeres, and anterior legs missing. Wings partially displaced ( Fig. 71 ).

PARALECTOTYPE ♀: blue-margined paralectotype disc; “41. 5. 17. 91.”; “E. Doubleday”; “ Arma grandis Walker’s catal.”; “a”; “NHMUK 010747385”. Fifth right antennomere, fourth and fifth left antennomeres, and left middle leg missing ( Fig. 72 ).

PARALECTOTYPE ♀: blue-margined paralectotype disc; “41 5. 17. 89.”; “E. Doubleday”; “ Arma grandis Walker’s catal.”; “a”; “NHMUK 010747386”. Right antenna, fourth and fifth left antennomeres, and right anterior leg missing. Wings disjointed ( Fig. 73 ).

PARALECTOTYPE ♀: blue-margined paralectotype disc; “ Arma grandis Walker’s catal.”; “93a”; “b”; “NHMUK 010935520”. Second to fifth antennomeres, and middle and posterior legs missing ( Fig. 74 ).

Current status: Apoecilus cynicus (Say, 1831) (synonymised by Uhler 1886: 4; see Distant 1900a: 59; Schouteden 1907: 71; Thomas 1992: 27).

Notes: Dallas had at least two specimens, since he listed male and female; Walker (1867a: 134) listed four specimens from Trenton Falls, presented by Doubleday. We have found four, all females (which matches the fact that Dallas had given a range of measurements for the female, “ ♀ lin. 9–10”). One of our four specimens, however, is not from Trenton Falls but is the specimen for which Dallas gave no provenance. Walker (1867a: 134) did not mention under Arma grandis any specimens from an unknown provenance. The male reported by Dallas must have been the fourth specimen from Trenton Falls. The label “93a” refers to the first specimen on page 93 in the first volume of Adam White’s unpublished “Catalogue of Hemiptera ” (White, A., no date) There reference is made to Samouelle’s Register ( Entomological Memorandums, 1838 –1840): “Reg. 999”. However, on page 174 of that register, no provenance is recorded for records 995 to 1001. Genus Pentatoma is dittoed for all specimens on this page. The provenance for record 994 (“ New Holland ” [ Australia]) can certainly not be dittoed. For further informations on White’s Catalogue of Hemiptera and other early catalogues at the Museum, see Wheeler (1996). Did Walker know that “93a” meant “Trenton Falls” or was there another specimen labelled similarly to the three from Trenton Falls, which is missing now? According to Burks (1975: 139), the specimens Doubleday collected at St John’s Bluff may be variously labelled: “St John’s Bluff”, “ East Florida, Doubleday” and “North America, Doubleday”. The same may be true with “Trenton Falls” for which labels could also read: “ New York, Doubleday” and “North America, Doubleday”. We know that, at least, one specimen of that species was sent to Melbourne by Francis Walker ( Walker 1985: 11). Public Library, Museums and National Gallery (Vic.), et al. (1890: 52) listed two specimens (numbers 52827 and 52828). They, however, cannot be from the type series as they come from Lake Huron. Thomas (1992: 27) stated: “I examined the female type of Arma grandis , located in the British Museum (Natural History). It is labeled (a) “Type,” (b) “E. Meday.” (c) “5-49 90.17,” (d) “3. Arma grandis .”” He thereby “unambiguously selected [this] particular syntype to act as the unique name-bearing type of the taxon” ( ICZN 1999, Art. 74.5).” This, regardless of the fact that the data of labels (b) and (c) are erroneous.
