Hololepta insignis, Sch. 



Sclimidt only knew the female of this species^ of which 

 the type is in the Berlin Museum. The male has no carina 

 on the mentura, the thoracic fossette is on the lateral border 

 distant from the angle and similarly placed to that o^ stern alls, 

 Lew., the anterior part of the prosternal keel is greatly 

 widened out, and nearly the whole of this widened portion 

 is excavated, the posterior margin alone remaining, and the 

 tenuous anterior edge has a sinuous outline. The mandibles 

 are very long and widely depressed in the middle. In the 

 Hololeptini a very important masculine character lies in the 

 form of the menton, but a very conspicuous secondary 

 chai'acter in some species is the presence or absence of a 

 thoracic fossette or fovea occurring in varying positions in 

 the anterior upper surface of the thorax. It is not a pei'- 

 sistent character, as it does not exist in all the species, and 

 in some it varies much in size according to the more or less 

 development of the individuals. The function of the foveas 

 is not apparent. 



Trypan<2us torpedo, Lewis, 1885. 



This species was discovered by Mr. Thomas Belt in 

 Nicaragua^ and at the same time specimens of Tesserocerus 

 belli, Sh., were found, and as both species are of similar 

 girth, the first is probably predaceous on the second ; both 

 species are for their kind very large. The smallest sj)ecies 

 of Trypeticus known is a native of Sumatra and is scarcely 

 larger than a fine thread_, and it would be very interesting to 

 discover the wood-borer whose passages are so minute.

 what opaque, rostrum a little swollen laterally, with tlie 

 apex acutely pointed and the tip a little raised ; the thorax
