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



typical Eros, having but three distinctly raised costse ; 

 the 1st costa is often abbreviated beyond the middle, the 

 2nd and 3rd start almost together from the humerus, 

 and the space between the 2nd and 3rd is wide at the 

 base, with a short intervening line representing the 4th. 

 Two specimens, a male and a female, taken at the 

 same time as others of this species at Fukushima, have 

 the antennae decidedly shorter, with more nearly quad- 

 rate joints, but I hesitate to consider them as specifically 

 distinct at present. 



Eros velatus, n. s. 



Niger, thorace subnitido ; elytris subopacis, inter-. 

 stitiis alternis et margine squamulis purpureis vestitis. 

 Antennis vix serratis. Long. 10 mm., ? . 



Kobe, on Maiyason. 



This Eros is very similarly coloured to several other 

 Lycidce, both from Japan and from the Malay district, 

 in being black, with the interstices (at least for a great 

 part of their length) covered with reddish velvety scales. 

 It is, however, the first species of Eros which I have 

 found so coloured, and the scales are brighter crimson 

 than in any of the allied species, nor do they extend to 

 the intervals or transverse ridges. The thorax has a dis- 

 tinct central diamond-shaped areolet. All the five areae 

 are uneven in their surfaces ; the intervals of the raised 

 interstices have distinct reticulate cells in a double 

 series ; the 2nd and 3rd of the raised interstices unite 

 before the apex. It is a rather broad and flat species, 

 and I think will be easily recognised ; at present only a 

 single female specimen has been found.

Platycis is one of the best of the modern divisions of 

 Eros, Newm., adopted from Thomson, Skand. Col., vi., 

 p. 162, by C. Waterhouse. Trans. Ent. Soc. Lond., 1878, 

 p. 101, for Eros (Lycus) minutus, F. So far as I know no 

 other species has yet been referred to it. The present 

 insect entirely agrees with the generic characters pre- 

 sented by P. minutus. The areolets in neither, however, 

 can be said to be well defined. The most striking
