722 MR. M. JACOBY ON THE [NoV. 3, 



Head impunctate, the frontal tubercles rather obsolete ; antennae 

 more than half the length of the body, entirely fulvous, the second 

 and third joints short and equal, the following joints not much 

 longer. Thorax about twice as broad as long, the sides straight, 

 the anterior angles oblique, surface rather convex, the basilar groove 

 deep and bounded at the sides by an equally deep longitudinal 

 groove ; within the former a transverse row of punctures is placed ; 

 the rest of the disk is impunctate. Scutellum very small. Elytra 

 narrowed and pointed at their apices, finely and regularly punctate- 

 striate, the punctuation nearly absent at the apices. Legs and 

 underside fulvous. 



Kashiwagi. 



Much smaller than C. lewisi; the sides of the thorax straight, the 

 punctuation more regular, and the antennaj and legs entirely fulvous. 

 From O.ferruginea, Scop., the species is distinguished by the im- 

 punctate thorax, the finer punctuation of the elytra, and the smaller 

 size. 



Crepidodera l^vicollis, sp. nov. 



Ovate, very convex, dark fulvous ; antennae and legs light fulvous ; 

 thorax impunctate ; elytra very finely punctate-striate, the inter- 

 stices flat. 



Length \\ line. 



Head impunctate, the frontal tubercles very obsolete, the space 

 between the antennae with a rather deep groove ; antennae entirely 

 light fulvous, more than half the length of the body, the third joint 

 one half longer than the second. Thorax transverse, the sides 

 rounded at the middle, somewhat narrowed at the base ; the basilar 

 groove straight, deep, and bounded at the sides by a still deeper 

 longitudinal groove ; surface entirely impunctate, with the exception 

 of a few punctures within the basilar sulcation. Elytra very convex, 

 the punctuation fine and here and there irregular on account of 

 some extra punctures, the striae more obsolete but yet visible to tlie 

 apex, the latter of somewhat ligliter colour than the rest of the 

 surface ; the first joint of the posterior tarsi longer than the two 

 following joints together. 



Oiwake. A single specimen. 



This species may be compared with C. exoleta, Fabr., and 

 C. intej-puncfata, Motsch., from both of which it differs sufficiently 

 to merit a specific name ; the interstices are here flat, not convex as 

 in C. exoleta, in which the head and thorax are also finely punctured. 

 The impunctate thorax and darker colour in general separate the 

 present species from that of Motschulsky ; the larger size and 

 rounded sides of the thorax from Q. recticoUis. 



Crepidodera acuminata, sp. nov. 



Oblong, narrowed behind, fulvous ; head and thorax impunctate; 

 elytra finely and regularly punctate-striate.
