Head and thorax reddish-testaceous, elytra and abdomen yellow, the 

 former occasionally infuscate about the postero-external angles. Antennae 

 reddish-testaceous. I^egs testaceous. Length 4 mm. 



In build very similar to Leptacinus filum Kr., but more robust. Head 

 oblong, wider than the thorax, the sides parallel, the posterior angles briefly 

 rounded ; median frontal furrows lightly curved inwards, with an umbilicate 

 puncture anteriorly ; lateral grooves deeper and narrower, oblique, extending 

 from an umbilicate puncture near the antero-internal border of the eye, back- 

 wards and inwards, to an umbilicate puncture behind the median groove but 

 not connected with it ; temples with two punctures, one close to the eye ; the 

 whole of the upper surface with a few small scattered punctures, ground sculpture 

 well marked, longitudinally strigose. Antennae with the 3rd joint a little 

 shorter than the 2nd, 4th about as long as broad, 5th to 10th transverse, the 

 penultimate about twice as broad as long. Thorax much longer than broad, 

 the sides straight, not much narrowed behind, all the angles rounded ; disc 

 with four larger quadrately placed punctures, another near the anterior angles 

 and another laterally ; besides these larger punctures there are a few fine 

 scattered ones ; ground sculpture strigose, more or less longitudinal. Scutellum 

 triangular with two fine setiferous punctures, transversely strigose. Elytra 

 as long as, but a Httle broader than, the thorax, obsoletely sculptured with 

 scattered larger and smaller punctures, the latter more nmnerous and without 

 ground sculpture. Abdomen practically impunctate along the middle, at the
