 MACROCHILUS LONGICOLLIS, n. sp. 



Brick-red ; elytra fuscous hlack, and having on each side a longi- 

 tudinal humeral brick-red band reaching from the base to a short 

 distance from the median part, and extending from the second stria 

 to near the edge of the outer margin, and a sub-transverse, compara- 

 tively narrow one of the same colour at the apex ; antennas with the 

 six apical joints dilated, the upper and lower surfaces are briefly 

 pubescent ; the head and prothorax are sub-foveolate-punctate, and 

 the punctures not closely set; the prothorax is unusually narrow and 

 elongated, being one-third longer than wide at its broadest part 

 which is at the apex, only slightly sinuate in the posterior part, the 

 sides of the base are strongly slanting towards the outer angle ; 

 elytra parallel, deeply striate, each interval, except the supra-mar- 

 ginal one, with one row of deep foveate punctures ; legs pubescent. 



Allied to J/. _/>rar/ms, which it greatly resembles in colour and 

 sculpture, but easily recognised by the narrow, elongated prothorax. 



Length 12 mm. ; width 3J mm.

MACROCHILUS SPECTANDUS, n. sp. 



Testaceous-red, with the 2-4 antennal joints and the abdomen 

 infuscate, the elytra are black and have on each side a sub-quadrate 

 yellowish patch situated slightly before the median part and extend- 

 ing from the third to the sixth interval, and an apical smaller one 

 extending from the first to the fourth stria and abutting nearly on 

 the apical outer margin ; it is clothed above and below and also on 

 the legs with a short flavescent pubescence ; the head and prothorax 

 are closely foveolato-punctate, the prothorax is as broad as long, 

 cordate, with the outer sides of the base incised transversely, thus 

 making the median part appear as if slightly produced behind ; the 

 elytra are parallel, deeply stfiate, with the intervals carinate in the 

 anterior part, convex in the posterior, and having each two series of 

 foveolate punctures. Allied to J/. biplagiatus, Boh., but the antennas
