HyprromorPHA (nov. gen. Cryptorhynchidarum). 
The following are the characters of a small insect, for which it seems necessary 
to provide a new generic name, and which is evidently somewhat allied to Acalles, 
while in some respects resembling Sympiezoscelus—though a careful comparison 
with the latter has led me to the opinion that its relation to it is not close. 
Rostrum rather short and wide as compared with Acalles, rather abruptly bent 
down close fo the base, gradually narrowed from the base for about a third of its 
length, then suddenly widened, and continuing about the same width almost to the 
apex, where again it is a little widened ; the whole of its upper surface clothed with 
short scaly sete; its serobes commencing about the middle, and running obliquely 
backwards to its base; antennze inserted about the middle of the rostrum, short, 
and not at all robust; scape gently increasing in thickness, and not reaching the 
eyes when set back ; funiculus seven-jointed, joints one and two about the same 
length, and longer than the rest, the other joints short (especially 5-7); club 
longer than wide, nearly as long as scape, not distinctly articulated ; eyes coarsely 
facetted, depressed, acuminated at the lower end, not approximated above ; pro- 
thorax considerably narrower than, and scarcely a third of the length of, the 
elytra—transverse, scarcely contracted at the base, but much contracted from the 
middle to the front, with gently rounded sides, its anterior border moderately 
produced over the head, its base truncated, the ocular lobes feeble ; scutellum not 
visible ; elytra about twice as long as together wide, very closely embracing the 
body, only moderately convex, and not abruptly sloped off behind, their sides 
nearly parallel (but slightly narrowed backwards) in the basal 3, in the apical 
fourth more strongly contracted, but quite obtuse at the apex; the whole upper 
surface clothed eyenly but not very densely with depressed scales, and quite 
devoid of inequalities; legs rather long and feeble, especially the femora, the 
lower side of which is rather deeply emarginate a little before the apex, the 
emargination being preceded by a small tooth; the tibize compressed, not very 
much enlarged towards the apex, where there is a small spine as in Acalles; the
