9. Agra mustela, n. sp. 
A. angustata, antice valde attenuata, nigro-zenea, antennis piceo- 
rufis, articulis apice nigris ; capite angusto, maris pone oculos 
conico vel in lineis rectis attenuato, femine elliptico vel 
leviter rotundato-attenuato; thorace gracili, grosse punctato, 
spatiis magnis levibus, episternis haud convexis, punctis 
grossis sparsis ; elytris pone basin sinuatis, deinde ampliatis,

$ Metasterno sparsim, trochanteribus segmentisque ventrali- 
bus plagiatim dense punctatis et longe fulvo-pilosis; tibiis 
intermediis et posticis intus densissime hirsutis, his medio 
leviter angulatis, illis prope apicem dente parvo instructis ; 
femoribus validioribus.

Ega. In the same situations as the preceding. It differs from 
A. infuscata, to which it is most closely related, by its smaller 
size and the less oblique truncation of the elytra, which causes the 
sutural angle to be less acute than in the allied species. The 
male differs from the corresponding sex of A. infuscata by the 
almost glabrous metasternum. These points of difference, it must 
be confessed, are much less important than those which separate 
the rest of these allied forms, and it is not without hesitation that 
I have described the present one as distinct.

A. elongata, subcylindrica, nigerrima, foveolis elytrorum viridi- 
punctatis; capite elongato-ovali, pone oculos rotundato- 
attenuato; thorace subcylindrico, prope apicem subito an-

$ Metasterno leviter, segmentis ventralibus 2—4 utrinque 
plagis dense punctatis et pilosis; tibiis intermediis et posticis
