wide, sides gently increasing in width from apex to near base, 

 and then suddenly narrowed ; with dense and fairly coarse 

 punctures. Elytra not very wide, each with a narrow sutural 

 stria; with dense punctures, small and rugose posteriorly; 

 some large ones on basal third. Length, 2^ mm. 



Hah.— Ylsit Rock Hole. Type (unique), I. 5184. 



A deep-black species, larger and more regularly clothed 

 than uniformis, with narrower elytra and shorter and almost 

 straight rostrum ; imitator is a smaller species, with darker 

 tibiae, shorter rostrum, and sparser clothing. On the basal 

 third of each elytron there are some fairly large punctures, 

 forming short irregular rows (about four) on the sutural half ; 

 immediately behind the shoulders there are some similar punc- 

 •tures, but with the linear arrangement less conspicuous.

Read small, concealed from above. Eyes lateral, coarsely 

 faceted. Rostrum long, rather thin, almost straight ; scrobes 

 invisible from above. Antennae inserted almost in exact 

 middle of sides of rostrum ; scape about half as long as funicle 

 and club combined, first joint of funicle as long as two follow- 

 ing combined, the others short ; club rather short. Pro- 

 thorax subcorneal, front rather strongly produced, ocular lobes 

 feeble, ficutellum apparently absent. Elytra distinctly wider 

 than prothorax, elongate subcordate, each separately rounded 

 at base. Pectoral canal deep and moderately wide, leaving 

 four front coxae exposed internally, and ending as a slight 

 notch in metasternum. Metasternum moderately long; epi- 

 sterna narrow. Two basal segments of abdomen elongate. 

 Legs not very long ; femora stout, edentate, not grooved ; tibiae 

 bisinuate on lower-surface, apex with a short stout spur; tarsi 

 rather short, third joint moderately bilobed but not wider than 

 the preceding ones, claw joint moderately long. Densely 

 squamose. 



A very curious genus of the C ryptorhynchides ; the type 

 in general appearance from above appears to belong to the 

 vicinity of A ch opera, but the pectoral canal is very different 

 to that of any of the allies of Chaetectetorus, except Derefiosus, 

 whose legs and prothorax are very different ; for the present, 

 however, it may be referred to the vicinity of that genus. The 

 structure of the under-surface is distinctly suggestive of 

 affinity with Microherosiris, but it differs in its head concealed 

 from above, prothorax longer than wide, with the sides scarcely 

 rounded, but obliquely decreasing in width from base to apex; 

 the tarsi are very different, the third joint being no wider 

 than the preceding ones (instead of much wider, as in that 

 ;genus), and the claw joint is almost as long as the others
