fuliginous ventral vitta on each side extended from middle of 

 third to apical margin of fifth segment, halfway between the 

 middle and the lateral margins, the laminately depressed 

 posterior border of the metapleura, the apical border of the 

 last male dorsal segment and often also a subquadrate lateral 

 spot to the ventral segments 2 to 5 and the sides of the last 

 ventral segments whitish ; tergum of abdomen with more or less 

 distinct fasciate or macular fuscous markings or suffused with 

 this color, the last segment unicolorous except a fuscous basal 

 spot; antennae and rostrum pale testaceous, second and third 

 antennal joints at apex and fourth at base (narrowly) and at 

 apex (broadly) dark fuscous, last two rostral joints piceous; 

 legs stramineous, and annulation before apex of femora and 

 extreme apex of tibiae and of tarsal joints fuscous. Head 

 strongly declivous (45^), immersed to the eyes, irregularly 

 punctulate above, clypeus impunctate, the callosity between 

 the bucculae and eyes oblique, first joint of antennae reaching a 

 little beyond apex of head, second somewhat more than twice 

 the length of first and as long as the distance between the inner 

 margins of the eyes, third subequal to second or a little shorter, 

 fourth sublinear but conspicuously thicker than the two preced- 

 ing ones and even slightly thicker than the first, rostrum a 

 little surpassing base of venter, first joint not reaching middle 

 of prosternum. Pronotum rather densely punctate, the trans- 

 verse callosity and three more or less distinct vittse on each side 

 of the posterior lobe remotely punctate; the apical margin of 

 the collar, the lateral hooked parts of the transverse callosity, 

 and a median line to the posterior lobe impunctate ; the posterior 

 lobe longitudinally convex, its anterior part and the anterior 

 lobe (except the collar) lying in the same strongly declivous 

 plane as the head, the collar much less slanting, forming an an- 

 gle with the posterior part of the anterior lobe. Scutellum 

 thickly punctate, the almost T-shaped callosity impunctate. 

 Pectus rather thickly punctate; anterior margin of prosternum, 

 a spot on propleui*£e and mesopleurae, the posterior laminate 

 border of the metapleurae, and the acetabula impunctate. 

 Abdomen impunctate; male genital segment near the base with 

 a small tubercle and behind this with a narrow, curved, trans- 

 verse impression. First joint of hind tarsi scarcely longer 

 than the other two together. 



Length, male, 3.5 millimeters, inclusive of membrane, 4.5; 

 female, 3.9 to 4.5, inclusive of membrane, 4.5 to 5.2.
