CBYPTOCEPHALrS. 215 



anteriorly ; mandibles black ; antennae very long and slender, 

 basal four joints flavous, rest black, third and fourth joints equal. 

 Thorax about one-half broader than long, strongly narrowed 

 anteriorly, the sides straight, median lobe short, deeply bi-emar- 

 ginate ; surface entirely impunctate, with a very slight depression 

 each side near the scutellum, which is triangular, edged with 

 black at base and with the usual fovea. Elytra rather broad and 

 robust, shoulders prominent, the sutural space round scutellum 

 raised ; the puncturation fine, not always regular but with some 

 extra punctures here and there, the seventh and eighth rows (not 

 counting the short subsutural one) more closely approximate and 

 more irregular. Legs slightly darker than rest of body. Prosternum 

 not produced in front, posterior angles pointed. Body beneath 

 very finely punctured. 



$ . Larger and more robust ; last abdominal segment with deep 

 cavity at middle. 



Length 4|-5 mm. 



Hub. Assam ; Burma : Karen Hills, Ruby Mines (Coll. Brit. 

 Mm.). 



Can be distinguished from C. cinnabarinus, Suffr. by the generally 

 testaceous colour and many other differences of details, and from 

 C. yestroi by the different elytral puncturation. 



381. Cryptocephalus hampsoni, sp. n. 



Above pale fulvous ; antennae (basal joints excepted), underside 

 and the legs more or less black ; anterior femora entirely or partly 

 flavous. 



Head sparingly but distinctly punctured at middle; clypeus 

 transverse, subquadrate, finely punctured, separated from face by 

 a transverse groove; eyes very broadly emarginate; mandibles 

 black ; antennae with the basal three or four joints flavous, third 

 and fourth equal. Thorax scarcely twice as broad as long, narrowed 

 in front, entirely impunctate, basal margin very narrowly black, 

 surface rather darker than elytra. Scutellum triangular, margined 

 with black. Elytra strongly punctate-striate, the punctures 

 piceous, distinct to apex although finer, extreme base and apex 

 paler yellow, interstices with a few fine punctures here and there, 

 also finely wrinkled near suture at base ; fifth and sixth rows of 

 punctures the shortest, joined at apex, ninth row placed farther 

 from the margin than the width between the other interstices. 

 First abdominal segment flavous at middle. Prosternuin rugosely 

 punctured, slightly produced anteriorly at middle, posterior margin 

 obsoletely bidentate. 



Length 4 mm. 



Hab. Nilgiris (HampsonColl. Brit. Mus.). 



This species also is allied to C. cinnabarinus, Suffr. but is smaller, 

 not red above but flavous, the elytral puncturation not fine but 

 strong and distinct to apex, the interstices not broad and smooth
