Apart from similarity of description, food plant, &c., we base our 

 belief in the equivalency of these two names on the fact that the types 

 of waterhousei returned by Kutschera to G. R. Waterhouse, now in the 

 " Waterhouse" collection, agree precisely with specimens returned by 

 M. Bedel to Mr. E. G. Elliman as his menthoe. In the European 

 Catalogue [Heyd., Reitt., and Weise, 1906] ■waterhousei, Kutsch., is 

 given as a var. of jnncicola, Foudr., but if, as we have reason to 

 suppose, juncicola, Foudr. ^= lycopi, All., this is clearly incorrect, for 

 waterhousei differs entii'ely from that species. Bedel doubtfully 

 suggests that L. cerinus, Foudr., may be synonymous with his menthfe, 

 and this may possibly be the case, although we are more inclined to 

 associate L. cerinus, Brit. Colls., with membranaceus, Foudr. 



Of a rather short and rounded oval. Head : dark ferruginous, very finely 

 and delicately punctured between the eyes. Antennae : long, testaceous, with 

 the last four or five joints inf uscate. Thorax : transverse, bordered, very variable 

 in character of punctiiation, from confluent and rather rugose to weak and 

 diffuse, bvit never very strong or deep ; very weakly alutaceous. Elytra : 

 straw-coloured or pale ferruginous with the peculiar translucent granular 

 appearance common to most of the apterous species, punctuation weak and 

 scattered, but usually rather stronger than that of the thorax, plainly seriate 

 near suture, finely alutaceous, sutiire narrowly and faintly rufescent ; there are 

 occasionally obscure traces of darker linear markings, caused possibly by the 

 partial semi-transparency of the elytra. Legs : entirely testaceous, with the 

 posterior femora only slightly darker or ferruginous, posterior tibial spurs long, 

 first joint of anterior tarsi not enlarged. Underside dark brown. Bedel 

 describes the species as apterous, and this is so in all the specimens we have 

 seen. Length, 1| — 2 mm.
