HILIPIMORPHUS.—HEMILUIOPSIS. 521 
beyond the middle, joints 8-7 of the funiculus transverse, 2 shorter than 1. Prothorax much broader 
than long, abruptly narrowed and feebly constricted in front, the sides parallel from the middle to the 
base, the dise flattened behind and obsoletely canaliculate towards the base and apex; closely, finely 
punctate. Elytra parallel in their basal third and narrowing thence to the rounded apex, which is 
broadly produced, the humeri not prominent, obliquely truncate in front; coarsely seriate-punctate, the 
interstices minutely punctulate, almost flat, the fifth swollen at its apex. Ventral segments 1-4 very 
sparsely and finely, and 5 coarsely, punctate. Anterior and intermediate tibize serrulate on the inner side 
between the median tooth and the apex, the posterior pair feebly dilated at the middle within. 
Length 75, breadth 3 millim. (¢.) 
Hab. Muxico, Ventanas in Durango (Forrer). 
One specimen. It is possible that the teeth on the inner edge of the tibia may prove 
to be wanting in the female sex. 
HEMILIUS. 
Hemilius, Chevrolat, Bull. Soc. Ent. Fr. 1880, p. exi (part.). 
H. glabrirostris is taken as the type of this genus. It has very strongly clavate, 
sharply dentate, compressed femora (the anterior pair being particularly stout); the 
tibie are neither toothed nor dilated externally at the apex; the tarsi are rather 
slender; the rostrum is narrowed towards the tip ; the rostral canal reaches to about 
the middle of the intermediate coxe; the ventral segments 2-4 are subequal in 
length ; the head is convex and rather small. The sexual differences are scarcely 
noticeable.

HEMILIOPSIS, gen. nov. 
Femora stout, compressed, moderately clavate, feebly unidentate, the anterior pair unarmed in the g. Tibix 
dentate externally at the apex, as well as strongly unguiculate at the outer apical angle and mucronate 
at: the inner angle, the anterior pair bowed in the ¢. Mesosternum broad, horseshoe-shaped. Ventral 
segments 2-4 equal in length, the sutures straight. Eyes very large. Rostrum short and stout. The 
other characters as in Hemilius. 
The type of this genus, Hemilius nudicollis, Chevr., is an interesting insect, 
superficially resembling H. glabrirostris, Boh., but more nearly related to the Chilian 
Empleurus dentipes, Boh. In the armature of the intermediate and posterior tibie it 
approaches the Australian Psepholax latirostris, Pasc.
