CAMPOSELLA n. gen.

Head hemispherical, the occiput but little swollen. Eyes pilose, contiguous from vertex to base of antennae and widely separated from this point to the mouth opening. the space being deeply excavated, although the proboscis is quite rudimentary. Antennae in male about four times the length of the head, the first Joint sunk in the head, the second ring-like and short, the third enormous. about as wide as the vertical diameter of the head, flattened and blade-like. Proboscis about as long as height of head, small, cylindrical. pointed and with fine hairs on the surface it is not rigid as in Lasía and Eulourlzus, and is clearly rudinıeııtary, not being adapted for feeding. Palpi are absent. The ocellar tubercle is rudimentary and there are no ocelli.

Thorax large and inflated as in Lasia , quite thickly pilose, the protlioracic lobes and upper pleura inflated and quite prominent. Upper surface of seutellum rather flattened. Postalar callosities of medium size. Squamae large and of thin texture, the surface and margins pilose. Legs of normal stoutness. all the tibiae enlarged at the tips and with a spur-like projection above. Tarsi slightly compressed laterally. Claws quite long and so formed that they can be brought together along the inner surfaces. Piil-rilli and "empodia absent.

Abdomen large and inflated in appearance, although. the venter is flattened. Pile of abdomen quite noticeable. Genitalia similar to those of Eulonchus. \ Wing venation very near that of Lasia , the lower branch of the fourth vein has disappeared, however, and the upper branch of the third vein ends in the first just beyond its juncture with the second. In Lasía this is a variable character, but is constant in the species as far as known.
