A pretty and very interesting little insect, about whose sy- 

 stematic position I am not quite satisfied ; however, I provision- 

 ally place it towards the end of the true Lebiidse. I find it most 

 to agree with the descriptions of Pentagonica, S. G., and Bhoiri' 

 hodera, U., with neither of which, however, it is identical. The 

 head is distinguished by the large and prominent eyes, and four 

 deep impressions, two larger ones at the root of the antennae, 

 two smaller ones between the eyes, also by a very distinct neck, 

 which connects it with the thorax; the labrum is large, trans- 

 verse and entire, with the angles rounded ofi" and the base nar- 

 rowed; the mentum is but slightly transversely emarginate, 

 edentate ; the ligula is truncated at the tip, the paraglossse 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 two strong, lateral angles 

 at the middle, each furnished with a strong bristle ; the anterior 

 part has the sides rounded, the posterior abruptly obliquely con- 

 tracted; at the base it is cylindric. As a specific distinction of 

 the thorax, I mention, moreover, that in the present species it is 

 impressed with two deep punctures before the middle, and that 

 it is rugose at the base. The abdomen is slightly peduncled.
