Mr. G. Lewis on 



behind tlie eyes, the abdomen has six free ventral segments, 

 and all the claws are pectinate, each claw being furnished inte- 

 riorly with a long appendage. In 1883 Leconte and Horn 

 (Class. Col. N. Am. p. 405) proposed the family name of 

 Cephaloidje, in which at present there is only one genus. 

 Newman placed the genus originally in the (Edemeridaj. 



Fiff. 10. 



Cephaloon sakurce, sp. n. 



Elongatum, angnstatum, pallide testaceum,sericeo-pube8cen8; capite, 



thorace supra elytrisque margiuibus infuscatis. 

 L. 9-14 mill. 



Elongate, narrow, parallel at the sides, very densely and 

 minutely sculptured, clothed with silken pubescence ; the 

 head testaceous, with upper surface in- 

 fuscate ; the thorax testaceous beneath, 

 disk and region behind the neck dusky ; 

 the scutellura somewhat dark ; the elytra 

 pale testaceous, with a lateral and sutural 

 infuscate border ; these bands usually 

 join apically, but only very rarely ante- 

 riorly as in fig. 10; the antennas are 

 usually testaceous, joints 9 to 10 alone 

 being sometimes dusky ; the legs, ante- 

 rior pair testaceous, intermediate and 

 posterior pairs (with the femora near 

 the tibia?) sometimes marked with a 

 dusky coloration; the abdomen, the 

 bases of each segment are narrowly in- 

 fuscate along the edges. Some ex- 

 amples are entirely testaceous. 



In all probability C. variahile and pallens, Motsch., are 

 colour-varieties of one species. In sixteen examples of 

 C. sakurce I have before me no two are similar in colour, and 

 I doubt if two could be found to match in a much larger 

 series. 



Bab. Miyanoshita, Subashiri, and Suyama. Beaten from 

 pear- and cherry-blossoms when the trees were in full flower.
