wardlj ill one specimen with tlie angular mark), and one, 

 transverse, subtpical — and the outer margin to near the apex, 

 orange-yellow, the head and prothorax closely, finely punctate, 

 the latter with coarser punctures intermixed, the elytra 

 roughly punctured. Head narrow ; antcnnse short, joints 

 7—10 transverse in ? . Prothorax narrowed anteriorly. 

 Elytra long, subparallel, costate laterally from the humeral 

 callus to the apical declivity, and with an anteriorly evane- 

 scent costa on the disc; the apices narrow and rounded or 

 subtruncate in cJ, a little wider, feebly emarginate, and with 

 the sutural angle angularly diluted inwards so as to overlap 

 the one on the opposite elytron, in ? . 



cJ . Metasternum with two compressed conical tubercles in 

 the middle behind. Ventral segment 5 deeply arcuato- 

 emarginate, 6 long, compressed (subcylindrical as seen in 

 profile with the terminal dorsal segment). Tegmen narrow, 

 subtruncate at tip, which is slightly hollowed dorsally and 

 clothed with long blackish hairs. Penis-sheath drawMi out 

 into a slender, feebly curved point. 



Length 6i-6|, breadth 2.i-2| mm. ((??.) 



Hah. Yeihezvela (€,v col/. Fri/). 



Three inaK s and one female, varying a little in the develop- 

 ment of the elyiral maikings, two of them being coalescent 

 in one specimen. Near A. octopustulatus^ Gorh., the spots 

 differently shaped, the second one on each elytron hooked, 

 the tooth at the outer angle in the ? reduced to a feeble 

 angulation, tin; dentiform sutural angle directed inwards and 

 overlapping the one on the opposite wing-case. 



38. Astylus imbricatu.'!, sp. n. 



? . Black, the elytra with three rather broad flavous vitise, 

 the two on the disc connected anteriorly, the sutural and 

 marginal ones broadly coalescent before the tip (leaving the 

 apical margin narrowly black), and the median one slightly 

 constricted posteriori}' ; the apices of the elytra sinuato- 

 truncate, the sutural angle sharp and overlapping the one on 

 the opposite wing-case; the elytial bicostate and lather 

 coarsely punctate. 



Length 5^, breadth 2 mm. 



Hah. Venezuela {excoU. Fry). 



One female. Snialler and narrower than the smallest 

 example of A. vittalus^ var. cJiiritjiiensis, the apices of the
