46 Mr. F. P. Pascoe's Descriptions of New Genera 



sparingly interspersed; a black triangular spot between and 

 rather behind the eyes ; prothorax with one central and two 

 black mamillated shining tubercles ; each elytron with two 

 greenish black median patches, one discoidal, the other at the side 

 beneath it ; sides of the mesothorax and first abdonninal segments 

 black ; antennae with the third and fourth joints yellowish, the 

 rest black ; tarsi and ends of the femora black. 

 Length 7 lines. 



Entelopes Wallacei. 



E. rubro-fulva ; elytris punctatis, pectore ventreque nigris ; 

 pedibus fulvis ; femoribus posticis nigris. Borneo. 



Ofa dull brick red colour, with the elytra much punctured; 

 eyes black, antennae pale ; legs pale reddish yellow, thighs of the 

 posterior pair of legs almost entirely black ; metathorax and abdo- 

 men black. 



Length 6 lines. 



The form of this species is more elongate than in E. glauca, and 

 there is no trace of any spots. It appears to be very rare, as Mr. 

 Wallace has sent but a single specimen to England.* 



DiALEGES. 



$ Head with the neck long, the eyes entirely divided, the palpi 

 equal ; antennae longer than the body, with the basal joint short 

 and thick, the third very long, and this with the four or five fol- 

 lowing nodose, and densely ciliated beneath ; thorax elongate, 

 unarmed, narrower before and transversely wrinkled ; elytra long, 

 narrow, truncate and spined at each angle ; legs rather long, the 

 femora very robust, the tarsi compressed. 



Dialeges differs from the restricted genus Cerambyx {Hamma- 

 ticherus) in its divided eyes, ciliated antennae, the remarkable 

 elongation of its neck, and the thorax without the lateral spine. 



• Since this paper was read, I liave seen Dejean's specimen of Entelopes bre- 

 vicollis (E. glauca, Buq.), in M. Chevrolat's collection, and I have liule doubt of 

 its being the same species as that which I have figured under the supposition of its 

 being distinct. It wants, however, the apical spot, and on comparison there may 

 be other differences. It is from Java. Mr. Wallace sends another insect from 

 Malacca, smaller, with larger spots, which he considers to be specifically distinct ; 

 as he has had the advantage of seeing them in a living state, there may be some 

 diflferences in their habits or economy which has led him to this opinion. In this 

 case, Dejean's E. brevicollis will be a third species, and E. Wallacei will then 

 rank as a fourth.
