202 MR. M. JACOBY ON NEW [Fcl). 17, 



arranged in rather close rows, the mterspaces somewhat transversely 

 wrinkled. Legs robust and rather short, the anterior tibiae much 

 flattened and dilated, their inner margin broadly rounded. Abdomen 

 more or less testaceous, rest of the underside piceous. 



Nikko. 



The three specimens obtained by Mr. Lewis are all males, and 

 scarcely differ from eacli other. In one the anterior margin of the 

 thorax is very narrowly flavous, and two obscure small spots of the 

 same colour are visible on the elytra immediately below the scutellum, 

 indicating doubtless that the general colour of the upper surface is 

 liable to variation, so that probably individuals may exist in which 

 the yellow colour predominates, as is the case in the closely allied 

 C. pini of Europe. This latter species has the same curious 

 dilatation of the anterior tibise, but is, I think, a distinct, although 

 closely allied, species. The thorax in the present insect is longer, 

 less transverse, more widened behind, the surface still more closely 

 and finely punctured, and the entire coloration quite different from 

 C. pini, but the same in the three specimens before me except in 

 regard to the slight variation mentioned above ; the lateral margin 

 (narrowly) and the apex of the elytra (broadly) are flavous in all of 

 them. 



Cryptocephalus liothorax, Solsky. 



Var. signaticeps, Baly. C. multiplex 1 Suffr. 



According to Dr. Kraatz these two forms must be looked upon 

 as representing the same species. 1 believe, however, that the 

 synonyms of this and several allied species are not at all clear and 

 settled. Solsky, for example, makes no mention of the distinct 

 white spot at the apex of the femora, visible in the type described by 

 Mr. Baly before me, and in all the other Japanese specimens 1 have 

 for comparison. Amongst these there is a variety (differing in no 

 other way but that of colour) which agrees perfectly with one 

 described by Suffrian as C. multiplex from India, which I am in- 

 clined to look upon as identical with the present species, since I 

 cannot find any characters by which it may be distinguished. Curi- 

 ously enough Suffrian, in spite of the particular and lengthened 

 descriptions of all his species, makes no mention of the sculpture of 

 the thorax in C. multiplex. Besides these named species, there are 

 several others, very closely allied, C transversalis, Suffr., C. luridi- 

 pennis, which may prove eventually to be but varieties of C. lio- 

 thorax, which is evidently an extremely variable species. At all 

 events, I have little doubt about the identity of C. multiplex and the 

 present insect. Another apparently very closely allied species is C. 

 tetrathyrus, Solsky, which agrees again very nearly with C. multi- 

 plex and with some varieties obtained by Mr. Lewis, except that the 

 anterior legs in Solsky's species are described as testaceous. In the 

 Japanese variety the elytra are black, with the exception of the 

 lateral margin anteriorly, and connected with a rufous transverse 

 band ; another similarly coloured round spot is placed at the apex ; 

 all this and the rest agreeing with the description of C. multiplex.
