Fig. 101. Cryptocephalus rajah. 



Head very sparingly punctured, obsoletely longitudinally 



depressed at middle ; clypeus 

 separated from face, strongly 

 etnarginate anteriorly ; an- 

 tennae long and slender, basal 



\>e^ * T -a, four joints flavous, third 



;,\ 7 J and fourth equal, fifth and 



following joints slightly 

 widened, terminal joint long 

 and slender. Thorax strongly 

 narrowed anteriorly, sides 

 nearly straight, posterior 

 margin finely serrate, disc 

 entirely impunctate. Scu- 

 tellum black at base, tri- 

 angular, \N ith the usual fovea. 

 Elytra narrowed posteriorly, the suture raised round scutellum ; 

 surface very finely punctate-striate, apex impunctate, interstices 

 broad and flat, a deep black round spot on shoulders and another 

 at apex of seventh and eighth rows of punctures. Underside very 

 finely punctured, slightly pubescent. Prosternum with anterior 

 margin strongly produced in front, posterior angles triangularly 

 pointed. 



Length 5 mm.

Larger than C. colon, Suffr., the thorax entirely impunctate, the 

 scutellum flavous, black only at base, the elytra without black 

 lateral margins, their surface even more finely punctured and 

 without punctures on interstices. C. tetrastigma, Suffr., seems 

 closely allied, but has the elytra sculptured as in C. colon, and has 

 the anterior margin of the prosternum slightly produced. 



447. Cryptocephalus ducalis, sp. n. 



Obscure dark fulvous ; thorax with an obsolete black band near 

 base. Elytra with one humeral and one subapical black spot. 



$ . Large and robust. Head with two obsolete transverse 

 depressions, strongly punctured, space in front of eyes and 

 between antennao stained with black ; clypeus separated from the 

 face, deeply emarginate in front, finely punctured ; antenna) short, 

 fulvous, third and fourth joints equal, fifth and following joints 

 strongly flattened and widened, each not longer than the pre- 

 ceding joint. Thorax extremely convex, almost subglobose, 

 posterior angles produced, margins narrowly black, surface en- 

 tirely impunctate, the base with a very obsolete transverse black 

 band. Elytra very slightly narrowed posteriorly, the suture 

 raised round scutellum; surface moderately strongly punctate- 

 striate, punctures distinct to apex, intermediate rows shortest, 

 each preceding and following row joined at apex ; epipleural lobes
