flagellum ; pubescence of the head pale whitish, thin and loose, most 

 abundant below the antennae, where it almost obscures the surface ; head 

 black, mandibles brownish, flagellum, except the first joint brownish 

 beneath. 



Thorax. — Prothorax rounded, presenting a transverse fold, dull, rugu- 

 lose ; dorsulum shining and with distinct punctures well separated on the 

 posterior half, the anterior half dull with the punctures almost adjoining ; 

 scutellum sculptured like the posterior half of the dorsulum, with a slight 

 median groove ; postcutellum rugulose ; metathorax with its superior 

 face scooped out and striated the striae rather close together and regular, 

 the central one strongest, posterior face with an indistinct sulcus, the sur- 

 face rugulose as is the surface of the metapleura ; legs with the following 

 peculiarities, anterior tibiae swollen, produced into an angle on the ante- 

 rior margin, this angle is notched and has a beak on one side of the 

 emargination, beyond the angle is a finger-nail-like production which 

 shuts down on the apical tubercle of the inner side of the metatarsus ; 

 metatarsus at base with a blunt production, the other tarsal joints of the 

 anterior legs not produced, claws cleft ; medial legs with the femora pro- 

 duced into a large triangular process posteriorly, that is as long as the 

 femur, tibiae almost triangular in outline, the production on the anterior 

 margin emarginate so as to give the appearance of a truncate process on 

 the anterior margin ; metatarsus broadly produced near the base, flattened 

 and laminate posteriorly on the apical half, apex anteriorly produced 

 into a blunt process the other tarsal joints as on the anterior legs ; pos- 

 terior legs with the femora produced posteriorly and drawn out into a 

 slender styloid process rounded at the tip and directed backward and 

 inward, tibiae broadly produced the production directed inward and pro- 

 vided with two strong processes, the anterior process like a claw and 

 directed forward and outward, the tip directed backward and outward, 

 the posterior process is broad and blunt, almost truncated and directed 

 downward and slightly outward, metatarsus somewhat flattened broad 

 and angulate on the posterior margin, first joint of the small tarsal joints 

 about as long as the next two together, the terminal joints as in the mid- 

 dle and anterior legs ; wings brownish, nervures very dark brown, stigma 

 nearly black, first recurrent nervure nearly interstitial with the first trans- 

 verse cubitus. Abdomen shining, rather coarsely tessellate, the broad 

 margins brownish, distinctly depressed and minutely punctured, fifth 

 ventral segment with a triangular space sharply outlined, terminal dorsal 

 segment with a narrow median impunctate space, at the apex of the 

 abdomen the pubescence is nearly as abundant as on the face below the 

 antennae. The metathorax and abdomen are less pubescent than the 

 rest of the body, first three dorsal segments with white pubescence ; the 

 fourth, fifth and sixth with black pubescence. Black, legs partly inclining 

 to brownish, apical two or three tarsal joints and claws brown.
