398 Kev. H. S. Gorham's revision of the 



Maxillary palpi with the apical joint wider at its base 

 than the preceding one, somewhat conical. Antennse of 

 the male with joints 3 — 10 gradually shortening in 

 length, with lengthened flabellate branches, the end 

 joint being finally nearly as long as the branch of the 

 joint before it ; the whole antenna about two-thirds of 

 the body's length. Thorax rounded in front, but a little 

 sinuate, varying in different specimens ; in the larger 

 ones (which have at the same time more crimson-red 

 elytra) it is usually but slightly contracted before the 

 hind angles, which are produced and very acute ; in 

 smaller ones, and in some which have browner elytra, 

 there is a decided contraction of the sides immediately 

 before this acute hind angle ; the middle of the basal 

 margin rises to meet the very short basal carina, but is 

 scarcely emarginate. The elytra are either crimson, 

 with a rich purple hue, or brown. I cannot consider 

 the latter a distinct species ; they are very closely 

 covered with silky adpressed hairs ; no punctures or 

 reticulation whatever is visible. 



Although this species varies so much in size and 

 in colour, the larger specimens being more richly 

 coloured than the smaller ones, yet from an examination 

 of both the male and female types from Mr. Lewis' first 

 collection there is no doubt the fine series of specimens 

 brought by him from Nikko, Fukushima, and other 

 places in the main island, belong to the species described 

 by Kiesenwetter, who, however, failed to observe the 

 split claws. Identified by Bourgeois with L. flabellata, 

 Mots., but I feel doubtful on this point. 



Mesolycus, n. g. 



Characteres plerumque ut in Macrolycus, sed antennae 

 maris simpliciter serratse, prothoracis latera antice con- 

 vergentia, angulis posticis acutis baud valde productis ; 

 disco antice carinato. Ungues fissi, at maribus intermedii 

 ungue anteriori tantum fisso. Type, Mesolycus puniceus. 



This genus is remarkable, as being a second genus of 

 Lycidce with the claws split, or rather armed with 

 a spine near their points, Macrolycus having been the 

 only genus in which this kind of structure (which is 

 frequent in the Lampyridce and Telephoridce) has yet 

 been noticed. 



In the present genus not only is the only species 

 I have yet seen but of medium size, but what is very
