Description. Male holotype. Length 2.2 mm, width 2.0 mm. Dorsal surface entirely shiny, lacking microsculpture. Color brown ( Fig. 34 ); head dark brown with indistinct median yellowish–brown macula; pronotum yellowish brown; antenna, pronotal hypomeron yellow; mouthparts yellow except apical maxillary palpomere brown; legs, prosternum, mesosternum brownish yellow; remainder of ventral surface dark brown; abdomen pale yellowish brown except apically yellow. Head punctures small, separated by a diameter or less; pronotal punctures about as large as head punctures, separated by less than a diameter; elytral punctures larger than pronotal punctures, separated by a diameter or less; prosternal, mesosternal punctures small, separated by about 3 times a diameter; metasternal punctures as large as on mesosternum, small, separated by less than a diameter apically and laterally; absent medially; punctures on abdomen small, separated by about 3 times a diameter. Head with sides of frons parallel from base to apex, about twice width of eye measured at vertex ( Fig. 36 ); eye canthus short; apical maxillary palpomere slightly widened from base to apex, nearly parallel sided. Pronotum widest anterior to middle, reflexed lateral margin wide from base to apex. Epipleuron flat, narrow throughout. Prosternum rectangular, longer than wide, slightly longer than mesosternum, with apical margin arcuate. Postcoxal line on ventrite 1 short, evenly rounded, extended slightly more than ½ distance to apical margin of ventrite ( Fig. 35 ). Apex of ventrite 5 feebly arcuate. Genitalia with basal lobe longer than paramere, slender, parallel sided to rounded, weakly emarginate apex; paramere slender, parallel sided, slightly curved in lateral view apex rounded, dorsal margin without serrations ( Fig. 37–38 ); sipho robust, apical 1/4 broken in image ( Fig. 39 ).

Female. Unknown.

Variation. Unknown.

Type material. Holotype male; 23/84 (square green label)/(illegible locality), Mexico./Fry Coll. 1905. 100. ( BMNH).

Remarks. Cephaloscymnus beulah resembles most other species in this genus with male genitalia most similar to those of C. laevis . It differs from the latter species by pale dorsal surface; male head with median macula; and lack of black ventral surface.
