POLYDACRYS. 217 
ridge or groove, which is produced into a short carina or groove posteriorly, the scrobes descending to 
the lower surface ; funiculus 7-jointed; scape not reaching beyond the eyes, the latter large; mentum 
rather large, almost covering the maxille; vibrissee wanting or indistinguishable from the general 
vestiture* ; anterior coxse very narrowly separated; femora abruptly clavate, unarmed, the anterior 
pair stouter than the others; tibis setose, the anterior pair unguiculate and serrulate, the articular 
surface of the posterior pair open and slightly ascending ; body oblong, squamose and setose, fully 
winged. 
Polydacrys and Anypotactus seem to me to be more nearly related to Polydrosus 
than to Pandeleteius ; one species, however, here referred to the latter (P. hiero- 
glyphicus) has a similar nasal plate to the rostrum, but in that insect (as usual in 
Pandeleteius) the intermediate and posterior femora are comparatively slender and 
not clavate. The five Central-American species of Polydacrys, one of which is an 
abundant insect down to as far south as Costa Rica, may be tabulated thus :— 
a, Second joint of funiculus shorter or not longer than first; elytra with stiff 
suberect sete. 
a’. Eyes more or less prominent; elytral markings variable. 
a, Elytra not granulate ; sete moderately long or short.

6’. Eyes more depressed ; setze very numerous, short ; elytra nigro-fasciate or 
nigro-maculate . 6. 6 ww ee ee ee ee ee ee ntgrofasciatus. 
b. Second joint of funiculus much longer than first; elytra with very short, 
decumbent, curled, hair-like scales intermixed with the larger ones, nigro- 
fasciate; eyes very prominent ; prothorax strongly transverse . . . . . brevicullis.
