genera and species of Malacoderm Coleoptera. 401 



This elegant species is so near E. coccineus, L., that 

 it will suffice to point out the difference. It is of course 

 much smaller than average specimens of that insect. 

 The antennae are longer and thinner, less compressed, 

 and with the 3rd joint smaller than in the males of 

 E. coccineus. The thorax has in its centre a wide 

 lozenge- shaped area ; in E. coccineus this area is joined 

 to the base by a short carina ; here its apex is on the 

 base. 



Eros oculatus. 



Niger, prothorace infuscato, margine toto tenuiter 

 rufo, elytris rubricatis. Long. 7 — 8 mm., $ , $ . 



Mas. Antennis quam corpus paullo brevioribus, oculis 

 subglobosis, prominentibus. 



Femina. Antennis brevioribus, oculis baud promi- 

 nentibus. 



Hakone and Miyanoshita. 



Closely allied to the last species, smaller, with more 

 prominent eyes, and the whole disk of the thorax pitchy 

 black, or at least infuscato ; in addition to these dis- 

 tinctions the thorax is proportionally smaller, the ridges 

 separating the areolets are not so much raised, and the 

 transverse one dividing the two front ones from the two 

 posterior is not carried so far back towards the hind 

 angles. Of the elytra the intercostal spaces are narrower, 

 and the double row of square meshes not so even or so 

 distinct. 



The single female specimen is smaller than the two 

 males met with by Mr. Lewis ; this is no doubt merely 

 accidental. 



Eros spinicoxis. 



Eros spinicoxis, Kiesenw., Berl. Ent. Zeits., 1874, 

 p. 254. 



Konose; Nara; Nikko; Fukushima. 



When this species is in fine condition the elytra appear 

 brownish red from the fine pubescence with which they 

 are covered ; other specimens are quite black. I have 

 carefully examined the female type specimen, as well ;is 

 several others identical, as I think, with it, of both 

 sexes, and I cannot discover the coxal spines mentioned 

 by Kiesenwetter. The trochanters are triangular and 

 dentiform, as is usual in this family ; the coxae appear 

 to me to be quite simple. This cannot be considered a
