 slender, a little more than half the length of the elytra, black, the 

 third joint slightly ferruginous. Thorax rather small, narrowed in

(Plate III. fig. 5.) 



Lycus analis, Dalm., Schonh. Syn. Ins., iii. App. p. 30, t. 5. f. 10. 

 Lycus divisus, Walker, Ann. 8f Mag. Nat. Hist., 1858, ii. p. 282. 

 Lycus planicornis, Walker, I. c. 



Ochraceus ; antennis (basi excepto), tarsis elytrorumque apice 

 nigris. Long. 4^-7 lin., lat. 2|-3| lin. 



Hah. Ceylon {Dr. Thivaites); N. Bengal {Lieut. Campbell); Dacca 

 {J. C. Bowring, Esq.). 



This species is very close to L. internexus, but has the teguments 

 rather more delicate, the colour is paler ; it is usually of a broader 

 form, and the elytra are more ample, the sides posteriorly being 

 more strongly arcuate. The antennge have the first three joints 

 usually pale, but some examples have as many as seven pale joints. 



(S . Legs black, with the base of the femora pale. 



5 . Legs yellowish, with the tarsi and sometimes the apex of the 

 tibiae black. 



Mr. Walker's type of L. divisus is merely a small example of his 

 L. planico7'nis: both are females. 



Lycostomus nigripes. 

 (Plate III. fig. 6.) 

 Pyrochroa nigripes, Fahr., Mant. Ins., i. p. 163. 



Rufo-testaceus ; antennis articulis 4'°-ll"'", femorum apice, tibiis 

 tarsisque nigris ; thorace triangulari, sericeo-pubescenti ; elytris 

 postice sat ampliatis. Long. 5| lin., lat. 2| lin.
