400 Eev. H. S. Gorham's revision of the 



Two specimens (males) agree with the type of this 

 species ; these are entirely black, 8 mm. in length ; the 

 thorax with the usual seven areolets, the antennae pecti- 

 nate, but with these a considerable series of larger 

 specimens appear to be conspecific, which have the 

 elytra red-brown at the base for nearly half their length, 

 owing to the scales with which their costae and all the 

 raised parts are thickly clothed being of that colour. 



This insect agrees very nearly in colour with several 

 LycidcB from Borneo, Sumatra, and the adjacent islands, 

 of which an account will be found under M. infuscatus, 

 in ' Notes from the Leyden Museum,' vol. iv., p. 9G, 

 1882. The rufous scales are no doubt very easily. 

 removed by friction or wet, which was probably the 

 case with the specimens from which it was described. 



Eros, Newman. 

 The type of Eros is L. coccineus, L., aurora, Herbst, 

 and of English writers. The thorax has five areolets ; 

 the antennas are simple, or only slightly serrate, much 

 longer in the male than in the female. The elytra have 

 the alternate four costae more raised than the lines 

 which separate the double rows of cells between them, 

 of which there are thus ten between the suture and the 

 margin. This definition will exclude such species as 

 D. affinis, Payk., and L. minutus, F., for which the 

 genera Pyropterus, Mulsant, and Platycis, Thompson, 

 are adopted by all students of the Lycida now. But one 

 of the species described by Kiesenwetter as Eros can be 

 referred to that genus ; they will be found here under 

 the genera to which, in the present state of the syste- 

 matic arrangement of this family, they pertain. Two 

 species, Eros granicollis and E. atrorufus, Kiesenw., 

 Deuts. Ent. Zeits., 1879, p. 305, I cannot refer to their 

 proper genera, or identify with any of Mr. Lewis' species. 

 No size is given, but they are, I suspect, Platerotes. Mr. 

 Lewis' last journey has proved, however, that true Eros 

 are in Japan.
