THE ENTOMOLOGIST. 



is moderately closely and distinctly punctured (Weise calls the 

 punctuation obscure), and that there is a lateral depression 

 distinctly visible in the female, less so in the male, at each side ; 

 C. nasutulus is allied to G. fortunatus, G. approximates, Baly, 

 C. kulibini, Gebl., and G. splendens, Kraatz. 



Cryptocephalus festivus, n. sp. (Plate I., fig. 4.) 

 Flavous ; the terminal joints of the antennae and the middle of the 

 breast and abdomen black ; thorax impunctate ; elytra violaceous-blue, 

 strongly punctate-striate, the interspaces smooth, the lateral margin ante- 

 riorly flavous. Length, 1£ — 2 lines. 



Head nearly impunctate, flavous, the extreme vertex blackish with a 

 few fine punctures ; antennae long and slender, two-thirds the length of the 

 body, the lower four joints flavous, the rest black ; thorax transverse, strongly 

 narrowed in front, the sides but moderately deflexed with a narrow margin, 

 the lateral margin nearly straight, the surface entirely impunctate, flavous ; 

 scutellum black, slightly longer than broad, its apex truncate ; elytra regu- 

 larly and strongly punctate-striate, the punctures distinct to the apex, 

 metallic violaceous, the interstices flat and impunctate, the anterior margin 

 and the epipleurae at the base flavous ; pygidium, under side and legs pale 

 flavous, the centre of the lower portion of the breast and of the abdomen 

 black, the apex of the last abdominal segment in the male slightly emar- 

 ginate at the middle, that of the female with the usual deep fovea. 



I am not acquainted with any eastern Cryptocephalus agreeing 

 in coloration with the present insect, of which a dozen specimens 

 were received ; the flavous colour of the lateral margin and of 

 the epipleurse extends to the middle of the elytra. 



Cryptocephalus flavopictus, n. sp. (Plate I., fig. 5.) 

 Black, finely pubescent ; three spots at the head, the anterior and lateral 

 margin of the thorax, and two basal spots (sometimes absent) of the latter, 

 flavous ; thorax closely punctured ; elytra strongly punctured, flavous, the 

 suture and two transverse narrow bands connected with a lateral longitudinal 

 stripe, black ; legs fulvous. Length, 2 lines. 



Head rather closely punctured, finely pubescent, longitudinally depressed 

 at the vertex, black, two spots above the eyes and the epistome bright flavous ; 

 antennae two-thirds the length of the body, the lower five joints fulvous, the 

 others black ; thorax subcylindrical, much narrowed in front, the sides 

 strongly deflexed, the lateral margins nearly straight, the surface closely and 

 finely punctured and pubescent, black, the anterior and lateral margins 

 flavous (the former narrowly widened at the middle, the latter widened at 

 the angles) ; scutellum scarcely raised, slightly longer than broad, its apex 

 truncate, black ; elytra sparingly clothed with short yellow pubescence, 

 closely and strongly punctate striate, flavous, with a narrow black transverse 

 sinuate band before and another below the middle connected with the 

 black suture, and a similarly coloured stripe running parallel to the lateral 

 margin, — this latter band does not extend to the apex ; pygidium black, its 

 lower edge flavous ; the under side black, the anterior coxse and the legs 

 fulvous, the femora pale flavous at their apex. 



C . flavopictus resembles much in its coloration C. pustulatus, 

 Ross, and allied forms, but differs in the finely pubescent upper 

 surface, and in the close and somewhat elongate punctuation of 

 the thorax ; the two basal spots in front of the scutellum are 

 frequently absent ; the elytra in the male insect show deep rows
