348 Mr. G. C. Champion on various 



elytra greenish, nigro-cseruleous, or black, with an elongate 

 streak at the middle of the base, two or three shorter streaks 

 (including one near the outer margin) below this, and a large 

 irregular annulus before the apex, all sometimes coalescent 

 or partly obsolete, flavescent or rufo-testaceous ; the head, 

 prothorax, and scutellum closely, finely punctate, the elytra 

 foveolato-punctate, with minute punctures in the narrow 

 interspaces. Head small, the anterior portion short ; antennse 

 moderately long in $ , shorter in ? . Prothorax transverse, 

 rounded at the sides in both sexes. Elytra subparallel to 

 about the middle, the humeri tumid, the apical margin finely 

 crenulate. 



$ . Ventral segments broadly arcuato-emarginate, 6 about 

 as long as the lateral portions of 5, without groove, deeply, 

 triangularly notched at the tip. Tegmen with long, com- 

 pressed, narrowly separated, lateral lobes, which are rounded 

 and flavo-ciliate at the apex. Penis-sheath pointed at the 

 tip. 



Length 6-7, breadth 2§-3| mm. (<? $ .) 



Hub. ECUADOR, Tioloma, alt. 4263 metres (sec. Bourgeois : 

 type), Caflar (Rosenberg ex coll. Fry : £ ? ). 



The above desciiption is taken from four males and one 

 female from Oanar, which vary greatly in the development 

 of the elytral markings. A. riveti, Bourg., from Tioloma, 

 based on a single example ( ? ?), seems to belong to the same 

 species. The elytra in the insect before me are more coarsely 

 punctured than in the allied A. bourgeoisie Kirsch ( = bissex- 

 guttatus, Gorh.), a common species in the Andes of Ecuador, 

 and equally variable in colour. In one example ( <$) of the 

 present insect the markings are entirely wanting on the basal 

 half of the elytra, and in another ( ? ) the elytra (as in the 

 type of A. riveti) are rufo-testaceous, with the sutural and 

 outer margins, and four irregular angular patches black. 



14. Astylus sexpustulatus, sp. n. 



Moderately elongate, shining, the elytra duller, sparsely 

 nigro-pilose ; nigro-jeneous, the basal joints of the antennae 

 partly red, the elytra black, each with six sharply defined 

 orange-yellow spots — one, transverse, rather large, at the 

 base, one small, beneath the humeral callus (not visible from 

 above), one oblong, subquadrate, lateral, at about the basal 

 third, one, small, oval, near the suture, before the middle, 

 one, oblique, on the outer part of the disc, beyond the middle, 

 and one, rather large, triangular, near the apex; the head and 

 prothorax closely, finely, the elytra very coarsely, punctured.
