strongly raised in front, rather densely asperate and very faintly 

 pubescent; the sides clothed with pubescence of a pale -olden 

 colour Elytra narrowed from the base to the middle, approxnnate 

 at the 'suture only in the anterior sixth of their length ; each ess 

 than half as broad at the middle as at the base, narrow and of 

 almost equal width from the middle up to about one-seventh ot its 

 len-th from the apes, then widened slightly, acuminate and ended 

 in a sliar.) spine at tlie apex ; the surface rather densely asperate- 

 punctate the punctures denser on the dark ante-median spot and 

 posterior band. Sides of breast and abdomen with pale golden 

 pubescence mixed with longer grey hairs. 



Length 20 ; hreadtli 4| mm. 



Hah. Tenasserim : Tavoy {Dolurty). 



Group CLYTINL 



Head short, vertical or subvertical in front; gen se generally 

 rather Ion- ; eyes finely facetted, emarginate ; mandib es short ; 

 palpi short, subequal, the last joint more or less triangular Pro- 

 thorax usually unarmed at the sides, varying in form from globular 

 to cylindrical. Scutellum generally small. Front coxaj globular, 

 as a rule not prominent; their acetabula rounded on the outer 

 side open posteriorly. Acetabula of middle coxce open to the 

 epimera. Hind legs" generally long, the first joint_ of the tarsus 

 much lou-er as a rule than the second and third united ; spurs ot 

 hind tibi.^ long. Tarsal claws widely divergent. The episterna 

 of the metathorax generally rather broad, but m some forms more 

 or less considerably overlapped by the sides of the elvtra. 



In this group I include the Clytkles and Ancujhjptuhs ot Lacor- 

 daire to-ether with the genus Demoncuv of Thomson. Lacordaire s 

 restriction of the group, on the one hand, to forms m which the 

 antenna are at most only a little longer than the body m the _c? , 

 and on the other, to those in which the first 30int of the hind 

 tar4 is distinctly longer than the next two joints united, is one 

 which cannot be maintained. AVithin the group there is a regular 

 gradation in the length of the antennae from forms m which these 

 or-ans are less than half the length of the body to others in which 

 they are more than twice as long as the body ; and so also m regard 

 to the hind tarsi, the first joint is in some forms scarcely longer 

 than the second, in others more than three times as long as the 

 second and third united, while between the two extremes there is 

 almost every intermediate degree. On account of the gradual 

 modifications not only in these but in many other points ot struc- 

 ture, the genera cannot be defined with any great amount ot 

 precision. In fact there is something to be said m favour ot 

 those entomologists who describe each new species of the group as a 

 ChitHS The chief objection to this course is that, unless the 

 structural characters are given somewhat in detail, it becomes 

 quite impossible to identify the species.
