Hulolepta insignis, Sch. 



Schmidt only knew the female of thi« species, of whicli 

 the type is in the Berlin Muscnm. The male lias no carina 

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

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

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

 widened ont, and nearly the whole of this widened porticni 

 is excavated, the ])osterior margin alone remaining, and the 

 tennous anterior edge has a sinuons outline. The mandibles 

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

 Hololeptiui a very important masculine character lies in the 

 form of the mentou, but a very conspicuous secondary 

 character 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 per- 

 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 foveaj 

 is not apparent. 



Trypanceus 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.

 acute producto ; pronoto antice punctato baud tuberculato ;

L. 6i mill. 



^ . Cylindrical, robust, black and shining ; the forehead 

 flattened between the eyes, no ocular tubercle, surface some- 

 what opaque, rostrum a little swollen laterally, with the 

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

 margined laterally and anterior area for about one-fifth 

 of the length distinctly punctured, but without tubercles, 

 the remaining surface is finely and sparsely punctulate ; the
