A pretty and very interesting little insect, about whose systematic 

 position I am not quite satisfied ; however I provisonally place it 

 towards the end of the true Lebiidse. I find it most to agree with 

 the descriptions of the g. Pentagonica S. Gr. and Rhombodera E. 

 with neither of which, however, it is identical. The head is distin- 

 guished by the large and prominent eyes and 4 deep impressions, 2 

 larger ones at the root of the antennae, 2 smaller ones between the 

 eyes, also by a very distinct neck which connects it with the thorax ; 

 the labrum is large, transverse and entire, with the angles rounded 

 off and the base narrowed ; the mentum is but slightly transversely 

 emarginated, edentate ; the ligula is truncated at the tip, the para- 

 glossse adhere to it, reach a little beyond it and are obtuse at the 

 apex ; the palpi are rather long with the last joint elliptic, acuminate ; 

 the antennae are strong, filiform and reach beyond the shoulders, 

 joints 5-10 are of equal length and cylindric, 4-11 are pilose. The 

 most remarkable part of the insect is, however, the thorax which is 

 of a subrhomboidal shape, transverse, smaller than the head, as 

 broad again as long, it has 2 strong lateral angles at the middle, 

 each furnished with a strong bristle, the anterior part has the sides 

 rounded, the posterior abruptly obliquely contracted, at the base it 

 is cylindric. As a specific distinction of the thorax I mention more- 

 over that in the present species it is impressed with 2 deep punctures 

 before the middle and that it is rugose at the case. The abdomen 

 is slightly peduncled. The scutellum is slightly excavated. The 

 elytra are oval, rather convex and impressed with rows of punctures. 

 The legs are simple and weak, apparently equal in both sexes. The
