Longicornia Malayana. 607 



vix aequales, subfiliformes, articulo tertio caeteris 



paulo longiore. Prothorax late ovatus, aliquando 



oblongus. Elytra modice elongata^ apicibus rotun- 



datis vel truncatis. Pedes modice robusti, postici 



saepe valde longiores; tarsi postici articulo basali 



caeteris conjunctis duplo longiore. Prostermim an- 



gustatum. Mesosternum latum, antice declive. 



This is an unsatisfactory genus in regard to both habit 



and characters, the carinae in front, by which alone it is 



differentiated, being an arbitrary one. M. Chevrolat 



founded the genus on a Mexican insect {Glytus Sartorii) 



to which he afterwards added a number of others. 



§ Five carinae; two median, united to form a V-shaped 

 mark ; one on the vertex ; and one on each side near the 

 eye. 



Xylotrechus australis.

Grayish-black ; prothorax rounded, witn the sides ashy, 

 the dark central part forming a subcruciform figure ; ely- 

 tra with five yellowish bands, the three basal connected 

 along the suture, the fifth apical and oblique ; body 

 beneath black, a spot on each side of the mesothorax, 

 another on the epipleura of the metathorax, and one on 

 each side of the three basal abdominal segments, white; 

 legs grayish-black ; antennae dull ferruginous. 



Length 6 lines. 



X. crucicollis and suhscutellatus, Chev., appear to me to 

 be only slight modifications of X. australis ; X. Putzeysii 

 of the same author is probably only a variety. This is 

 the only Glytus-iovva. known to me that is common to 

 ^ew Guinea and Australia.
