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 Lasia and 

 Eulonchus, and is clearly rudimentary, not being adapted for 

 feeding. Palpi are absent. The ocellar tubercle is rudimen- 

 tary and there are no ocelli. 



Thorax large and inflated as in Lasia, quite thickly pilose, 

 the prothoracic lobes and upper pleura inflated and quite prom- 

 inent. Upper surface of scutellum rather flattened. Postalar 

 callosities of medium size. Squamae large and of thin tex- 

 ture, the surface and margins pilose. Legs of normal stout- 

 ness, 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. Pulvilli and -empodia absent. 



Abdomen large and inflated in appearance, although the 

 venter is flattened. Pile of abdomen quite noticeable. Geni- 

 talia similar to those of Eulonchus. Wing venation very near 

 that of Lasia; the lower branch of the fourth vein has dis- 

 appeared, however, and the upper branch of the third vein 

 ends in the first just beyond its juncture with the second. In 

 Lasia this is a variable character, but is constant in the species 

 as far as known. 



Genotype : CainposeUa insignata n. sp. 



C. insignata n. sp. 



$. — Length 13 mm., length of antennae 5 mm. Head and eyes 

 black with black pile. Eyes contiguous above and widely separated 

 below the antennae. Antennae contiguous at base, first joint scarcely 

 visible and yellow, second joint small, black and ring-like. The third 

 antennal joint has a rounded, short basal portion which expands into 

 a very large surface, flattened, very thin and rounded at the end. 

 The third joint is about four times as long as the head and about 6-10 

 as wide as long ; it is velvety black and destitute of pile. Proboscis 

 rudimentary, slender, cylindrical and pointed, covered with very short 

 black pile. Face black, deeply excavated below the antennae (see 

 PI. XI, fig. lb). Occiput slightly swollen, the cheeks shining black 

 and pointed below the eyes. Ocellar tubercle rudimentary, black, with 

 a central depression which is thinly black pilose ; ocelli absent.
