Mesothoracic sutures distinct, only in one species vanishing 

 posteriorly. Abdomen subsessile, convex ; terebra short, curved, 

 with broad cultrate valves, pointing forwards. Wings with 2 

 cubital areolets ; podiscoidal areolet narrowly open at the apex. 



Joints of the antennae cylindric, and closely conjoined. Abdomen 

 above ellipsoid ; 1st segment short, tubercles placed near the base ; 

 segments 2 — 3 together much longer than the 1st, smooth and 

 shining ; the following segments short, but not concealed ; anus of 

 the 5 compressed, decurved. Stigma ovate, lanceolate ; prse- 

 discoidal areolet not quite touching the parastigma ; 1st cubital 

 areolet separated from the praediscoidal ; recurrent nervure inter- 

 stitial ; cubital nervure faintly traced. The antennte and legs 

 offer no sexual peculiarities as in the Blacides. The species are of 

 rare occurrence, black and very shining, with hard integuments ; 

 the 2d abdominal segment is sometimes more or less red. We 

 have four species : — 



(6) 1. First abdominal segment subquadrate, not 



narrowed at the base ; claws of the J 

 bifid, of the ^ simple. 



(5) 2. Abdomen partly red. 



(4) 3. Hind cox^ produced into a strong tooth ; 

 ventral segments bidenticulate on their 

 hinder edge ; 2d abdominal segment en- 

 tirely, 3d at the sides and beneath, red . . 1. muricatm, Hal.
