138 CEEAMBYCIDJE. 



138. Margites modicus, sp. n. 



Dark brown, the head and prothorax nearly black, the antennae 

 and legs reddish brown ; faintly covered with short grey pubes- 

 cence. Head densely and rather finely punctured ; without 

 impressed line above. Antennae almost as long as the body in 

 the $, and about one-fourth longer in the.c?; third and fourth 

 joints rather strongly thickened towards the apex in the J, 

 slightly thickened in the $ . Prothorax evenly rounded at the 

 sides, narrowed and feebly marked with transverse grooves at the 

 base and apex ; the whole of the dorsal surface almost bare of 

 pubescence, and covered thickly with short irregular ridges, that 

 give it a somewhat coarsely granulated appearance ; the sides also 

 rugose, but covered somewhat thinly with pubescence. Elytra 

 finely and very densely punctate, the punctures somewhat stronger 

 on the basal area ; apices rounded. Femora finely and very 

 densely punctate; tibiaa carinate. There is considerable resem- 

 blance in colour and structure between this species and M. exiyuus, 

 Gahan, but a clearly marked difference in the form of the pro- 

 thorax, which is more or less regularly rounded at the sides in the 

 one, and obtusely subangulate in the other ; in the present species 

 also the rugosity of the pronotum extends nearly up to the front 

 and hind margins, whereas in M. exiguus it is confined to 

 the area lying between the anterior and posterior transverse 

 grooves. 



Length 13-17 ; breadth 3|-5 mm.

139. Margites sulcicollis, Gahan, A. M. N. H. (G) xi, p. 378 (1893). 



Head and prothorax black, sparsely setose; elytra brown, 

 covered with greyish tawny pubescence, with some longer sub- 

 erect tawny setaB interspersed ; body beneath, legs, and antenna 

 piceous or black, faintly covered with grey pubescence. Antenna3 

 shorter than the body in the $ ; first, third and fifth joints sub- 

 <?qual in length, each longer than the fourth and slightly shorter 

 than the sixth and succeeding joints. Prothorax constricted and 

 transversely grooved near base and apex ; rather strongly rounded 

 in the middle on each side ; the disc with two very distinct longi- 

 tudinal, slightly curved grooves, which mark off a median 

 suboblong area from two lateral areas, each of which is traversed 

 longitudinally by three or four narrow grooves separated from 

 ^ach other by sharp, cariniform intervals; the median area 

 sparsely punctate and feebly subsulcate along the middle. Elytra 

 rounded at the apex, very finely and densely punctulate, with 

 also sparser, larger sized punctures from which the suberect 

 setae arise. Femora densely and finely rugulose-punctate ; thq 

 tibia) not carinate. 



Length 13; breadth 3| mm.
