NEOCOLLYRIS. 



260 



sculptured ; femora, except apex, red ; anterior and intermediate 

 tibiae dark, posterior tibiae dark, with the apex more or less 

 broadly whitish testaceous ; tarsi, except claws, whitish testaceous. 

 Length 16-18 millim. 



Assam : Sylhet ; Sumatra ; Malacca ; Borneo. 



I have introduced this species into the Indian fauna on the 

 authority of a single female specimen labelled " Sylhet" in Mr. B. 

 C. Nevinson's collection (now in the British Museum), which agrees 

 exactly with typical specimens of N. sarawalensis, except that 

 the apex of the posterior tibiae is not so strongly coloured, and 

 the base is slightly more widened. It appears to me to be inter- 

 mediate between N. saraivaJcensis and N. dohertyi, as the plicae are 

 continued almost to the base near the suture, but the extreme 

 base and the sides of the posterior third are feebly punctured. 

 Dr. W. Horn thinks that a mistake has been made as to the 

 locality ; there is a single specimen (donor unknown) labelled 

 " Assam" in the Indian Museum collection. 



Var. dohertyi, W. Rom. 



Differs from the type chiefly in having the basal third part of 

 the elytra not obsoletely punctured, but rugosely plicate, and the 

 base itself coarsely and thickly punctured ; the trochanters and 

 the base of the femora are rufous yellow, and the palpi yellow or 

 brown with a greenish reflection. This variety is also related 

 to N. leucodactyla, Chaud., var. discolor, Chaud., from which it 

 may be known, apart from colour and sculpture, by the fact that 

 the pronotal collum is more distinct and the upper surface more 

 plainly striate transversely. 



Length 174-18J millim. 



Burma ; Sumatra ; Siam ; Malacca. 



Dr. Horn (I. c. p. 84) says that he was for long in doubt 

 whether to regard this insect as a species or a variety, and it may 

 be wrong to join it to N. sarawakensis, but, in view of the great 

 variability of the last-named species, it appears better to wait 

 for further specimens before separating them.

Collyris rubens, Bates, Cist. Ent. ii, 1878, p. 336. 



"Allied to 0. sarawakensis, Thorns., which it resembles. Casta- 

 neous red, with the antennae, head, breast, tibiae, and tarsi nigro- 

 aeneous ; head before the eyes widely excavate, with the frontal 

 furrows short and scarcely incised, the space between narrowly 

 convex ; thorax conical behind, strigose, constricted before the 

 middle, then convex before the apex, swollen ; elytra sparingly 

 and coarsely punctured at base and apex, in the centre very 

 coarsely rugose transversely, and on this part tinged with 

 cyaneous." 



Length 8^ lin. [17 millim.].
