into longitudinal strim. Elytra longer than thorax, narrowei 
behind, tips serrate, separately rounded, surface striate, stria 
with close-set punctures, as coarse as those of the thorax, in 
tervals wide, with a single row of equally coarse and close-se' 
punctures bearing at intervals conspicuous erect whitish bristles 
surface also more or less obliquely wrinkled, especially near thi 
sides and suture; humeral callosities feebly wrinkled. Surfao

punctate; thorax and legs sparsely hairy, disk of prosternun 
nearly glabrous; abdomen compressed at base, less coarseb 
punctate, clothed with erect bristles like those on elytra; de

base of abdomen to its apex; last segment concave near posterio 
margin. Length 2—2.5 mm. (PI. I., fig. 3.) 
Larva. —Oblong, cylindrical, thicker anteriorly, feebly shining

brownish dusky, semicircular, bearing on the anterior m argil 
three to five punctiform impressions and a few setae; mandible 
smooth, rather blunt; palpi Inarticulate, the basal joint paler 
short and thick, the second brownish, more slender, antenm 
two-jointed, minute, situated near the base of the mandibles 
just above this a puncture, which seems to contain a single minut 
ocellus. Thoracic segments somewhat thicker than the abdc

with the posterior margin deeply notched on each side, a denset 
granulate and opaque anterior and posterior border and medial 
line, the latter sulcate and narrowed in front, and lateral line 
extending forward each side from the notches in the posterio 
margin, but becoming obsolete before attaining the anterio
