This species is very close to L. ferriujineus, F,, but is relatively 

 a little shorter, and the elytra are less parallel, more ample poste- 

 riorly and more evidently arcuate at the sides. The antennae are 

 distinctly more slender. The thorax varies immensely in form, but 

 is generally narrower in the ^ than in the $ ; the disk is black, 

 frequently traversed by a fine mesial red line. The elytra are en- 

 tirely deep red ; a single example only has a short blackish stripe on 

 the second interstice. 



L. ferrugineus, F. (Ent. Syst. Suppl., p. 125), with which the pre- 

 sent species is above compared, will very probably prove to be a 

 variety of Lycus marginatus, Fabr. (Syst. El., ii. p. 110). L. mela- 

 nurus, Blanch. (Voy. Pole Sud, iv. p. 74, t. 6, f. 2), and L. hivit- 

 tatus, Kirsch (Mittheil. aus. d. k. zool. Museum zu Dresden, 1875, 

 i. p. 34), are evidently synonymous with marginatus. 



Lycostomus aequalis. 



(Plate II. fig. 7.) 



Niger, subparallelus ; thoracis limbo, elytris abdominisque lateri- 

 bus rufis. Long. 8 lin., lat. 3| lin. 

 Hah. China {J. C. Bowring, Esq.). 



Closely allied to similis, Hope, but much more parallel in form. 

 Antenna3 a little less slender than in that species. Kostrum a little 

 shorter, and thicker at the base. Thorax broad, blackish in the 

 middle. Elytra subparaUel, red, the costse nearly parallel ; at the 

 posterior two thirds, the fourth costa is not further distant from the 

 margin than it is from the third costa, the margin itself is more 

 thickened. 



The fine pubescence which clothes the upper surface of the insect 

 is more distinct than in similis and is golden red.
