1885.] PHYTOPHAGOUS COLEOPTERA OF JAPAN. 749 



MONOLEPTA FDLVICOLLIS, Sp. nOV. 



Black below ; head, three lower joints of the antennae, thorax, 

 and legs fulvous ; elytra greenish, closely punctured. 



Length 1| line. 



Head with a few fine punctures, only visible under a strong lens, 

 deeply transversely grooved between the eyes, the frontal tubercles 

 narrowly transverse and strongly raised; antennae black, the basal 

 joints fulvous, second and third joints short and equal. Thorax 

 transverse, fulvous like the head, distinctly but not very closely 

 punctured ; the disk with an obsolete transverse depression (acci- 

 dental ?). Elytra not more strongly but more closely punctured 

 than the thorax, the punctuations here and there arranged in lines 

 and distinct to the apices, the latter broadly rounded, not covering the 

 pygidium ; legs fulvous ; tarsi obscure fuscous ; the metatarsus of 

 the posterior legs longer than the three following joints ; pos- 

 terior tibiae with a distinct spine; anterior coxal cavities closed. 



Kashiwagi. A single specimen. 



MoNOLEPTA DiCHROA, Harold, var. (?) apicipennis. 



Black ; head, thorax, and the apex of the elytra flavous ; upper 

 surface very finely punctured. 



Length l|-2 lines. 



Head impunctate, transversely grooved between the antennae, the 

 latter as long as the body, black, the three basal joints testaceous, 

 the second and third very short and subequal. Thorax nearly twice 

 as broad as long, subquadrate, the sides and the posterior margin 

 slightly rounded, the surface impunctate, flavous or fulvous. Elytra 

 convex, slightly widened towards the middle, black, extremely finely 

 punctured, their apices in shape of a triangular spot, the point of 

 which extends upwards at the suture, flavous. Underside and legs 

 black, the anterior tibiae in some specimens and the knees of all the 

 legs more or less testaceous. 



Sapporo. Obtained in more than 20 specimens. 



Amongst all the specimens before me, there are two only which 

 answer to the description given by Von Harold of M. dichroa, which 

 may be but the variety of the normally coloured individuals with 

 fulvous apices of the elytra, of which I have given the above de- 

 scription. Whichever form is looked upon as the variet)', there is 

 little doubt about the identity of the present insect with that of Von 

 Harold. 



Genus Aenidea, Baly. 



In this genus several insects have been placed which certainly do 

 not belong to it. In A. laeta, Baly, which must be looked upon as 

 the type, the anterior coxal cavites are closed ; in A. armata, Baly, 

 and A. abdvminalis, Baly, both from Japan, the same cavities are 

 open and the last joint of the maxillary palpi is not incrassate. The 

 last-named species ought to find its place in Phyllobrotica, with 

 which it has the absent elytral epipleurae in common as well as all 

 other characters, as the examination of the type in Mr. Lewis's col-
