be distinguished by its larger size, broader pro thorax — with more 
deeply constricted base — thicker antennae, shorter and paler pubes- 
cence, feebler elytral punctuation, and more distinct scutellum.

Narrow, elongate, depressed, subopaque above, shining on 
undersurface. Brown; undersurface, coxae, base of femora, four 
anterior tibiae and tarsi, and antennae pale; elytra with two 
transverse white fasciae — the first near the base and parallel, 
except for a triangular encroachment at the suture behind, the 
posterior close to apex, straight in front, narrowing to suture from 
behind. Covered all over with very short, rather pale pubescence, 
with a few short erect hairs on elytra. Covered all over with 
extremely minute punctures, densest on head. 
Head longer than wide, scarcely obovate; eyes small, prominent, 
placed slightly before the exact middle; antennae slender, reaching 
anterior fascia, inserted considerably in front of eyes, 1st joint 
not as long as 2nd-3rd combined, 2nd not much shorter than 3rd, 
4th-10th slightly decreasing in length and as gradually thickening, 
11th not one and a half times as long as 10th. Prothorax not 
twice as long and scarcely as deep as wide; strongly rounded in 
front, constricted near the base, base narrowly margined: an 
almost obliterated tubercle on each side. Elytra scarcely longer 
than head and prothorax combined, slightly widest at the middle, 
base rounded as apex; without impressions. Legs — especially 
the posterior — -very long and thin, femora scarcely thickened, 
tibiae straight, longer than tarsi; 1st joint of posterior tarsi 
scarcely as long as the following combined, 2nd as long as 4th 
(including claws), 1st joint of intermediate as long as 2nd-3rd 
combined, of the anterior shorter. Length 3, width f mm.
