40 Longicornia Malayana. 



joints are still beyond the usual length, the sixth reaching to the 

 apex of the elytra ; the body is also narrower and less depressed, 

 and the scape, notwithstanding the shorter antennae, is very 

 decidedly longer, and more cylindrical, 



M'lcen'ia perversa. 



M. tenuiter pubescens, fusca; elytris cervino-pubescentibus, 

 plagis lateralibus brunneis. 



Hah. — Mysol, Bouru. 



Dark brown, with a very fine pubescence ; head as broad as 

 the prothovax, scarcely pubescent ; the eyes black ; prothorax 

 rather longer than broad, strongly punctured, the sides with a 

 short abrupt spine placed considerably behind the middle ; 

 scutellum rounded posteriorly; elytra strongly seriate-punctate, 

 covered with a greyish fawn-coloured pubescence, the sides with 

 transverse irregular patches of reddish-brown ; body beneath 

 testaceous-brown ; abdomen with a silvery pile ; legs and antennae 

 luteous, the latter about two-thirds as long again as the body. 



Length 2 lines. 



^iEgocidnus. 



Caput fronte subtransverso. Oculi majusculi, in vertice sub- 



approximati, antice distantes. Anlennm tenues, ciliata^ ; 



scapo modice elongato, fusifortni ; articulo tertio quarto 



breviore, cseteris gradatim brevioribus. Prothorax sub- 



quadratus, utrinque post medium spinosus. Elytra anguste 



oblonga. Femora valde clavata ; tarsi breves, postice 



angustati, articulo ultimo casteris breviore. Corpus baud 



setosura. 



A Le/opws-looking form, but narrower, with shorter tarsi, and a 



more median thoracic spine. Some of the obscurer species of 



Exocentrus (ante, p. 28) bear a marked resemblance to /Egocidnus, 



but they have less clavate femora and stouter aniennaj. The 



species of this genus are clotlied with a sort of silvery-greyish 



pubescence, having, however, at the side of each elytron, near 



the middle, a large bare patch ; the head and prothorax are very 



minutely and closely punctured, but, except in /E. juvtncus, the 



punctures are tolerably well marked on the elytra. 



^gocidnus grammicus. (PI. 111. fig. 2.) 



M. brimneus ; prothorace obsolete griseo-trilineato ; elytris 



griseo-sublincatis ; oculis nigris. 

 S^ah. — Bouru. 

 Reddish-brown; three small, longitudinal, hairy, greyish patches
