ACANTHOCININ^. 



The well-known A canthocimis cedilis and Leiopus nehulosus afford 

 good examples of the more usual forms of this sub-family, whicli 

 finds its greatest development in the tropical regions of the new 

 world. The Acanthocinince are distinguished from both Acantha- 

 derince and Colobotheince (neither of which have exponents in this 

 collection) by the short, often transverse, face ; from the former 

 also by the slender tarsi and antennae, the elongate scape, and less 

 robust body ; and from the latter by the body more or less de- 

 pressed, the prothorax toothed or angulated at the side, as well as 

 by the scape and tarsi, which do not, however, afford quite so 

 marked a contrast as they do with the A canthoderince . Besides 

 these characters, the Acanlhocinince have generally long and seta- 

 ceous antennae, arising from two diverging tubers, which have an 

 impressed line between them, and the second joint is almost in- 

 variably two or three times longer than broad, never transverse; 

 the eyes are reniform, often occupying a considerable portion of the 

 head ; the mandibles are feeble, and, when closed, generally pretty 

 well covered by the lip; the elytra are frequently truncate or 

 spinous at. the apex ; the anterior acetabula are entire, or only 

 slightly angulated ; the anterior and intermediate coxae are globose 

 and approximate at the base, with the pro- and meso-sterna simple 

 and declivous ; the femora are clavate ; the fore-legs are never 

 elongate in the males, although the posterior are occasionally, and 

 their tarsi are scarcely dilated and never fringed ; the claw-joint 

 varies in size, generally, however, small ; the three intermediate 

 segments of the abdomen are always the shortest ; the colour is 

 mostly ashy or greyish varied with brown, and there are often 

 setose hairs scattered among the pubescence. Many of the females 

 have lengthened ovipositors. 



Fourteen genera are in the collection, most of them very dis- 

 tinct ; none of them, so far as I am aware, occur either on the 

 mainland of Asia or in Australia.
