and Species of Hispidce. 369 



Very closely allied to Cephaloleia dilaticollis, the ^ 

 being very difficult to separate from the S of that 

 species; it may^ however, be known by its somewhat 

 narrower and slightly less depressed form, by the more 

 closely and distinctly punctured sides of the thorax, and 

 by the more distinctly rounded apices of the elytra; the 

 anal segment is also rather less deeply, but at the same 

 time more broadly, rotundate-emarginate ; the ? may be 

 at once separated by the bisinuate apex of the anal seg- 

 ment of the abdomen. In both sexes the second joint of 

 the antennae is distinctly shorter, taken in relation to 

 the third joint, than in 0. dilaticollis. 



(Sp. 9b.) Cephaloleia Amazona. 



Elongata, parallela, subdepressa, nigra, nitida, ab- 

 domine obscure fulvo-autnigro-piceo; thorace rufo-fulvo, 

 elytris fere gequilato, lateribus fere rectis, angulis anticis 

 rectangulis; elytris tenuiter punctato-striatis, punctis 

 apicem versus fere deletis. 



Mas : abdominis segmento anali late subangulato- 

 emarginato. 



Fern. : abdominis segmento anali bisinuato. 



Long. 21-3 lin. 



Hah. — Upper Amazons. 



Antennae less than half the length of the body, entirely 

 black, basal joint slightly thickened, rather longer than 

 the second. Thorax very similar in form to that of 

 G. laticollis, nearly equal in width to the elytra, sides 

 straight and slightly diverging along their hinder two- 

 thirds, thence also straight but slightly converging to 

 the anterior angles, the latter rectangular; the middle 

 portion of the anterior margin distinctly produced ; upper 

 surface transversely convex, concave on the sides, lateral 

 margin reflexed ; surface impressed with distinct round 

 punctures. Elytra scarcely broader than the thorax, 

 parallel, obtusely rounded at the apex, finely punctate- 

 striate, the whole surface very finely and irregularly 

 wrinkled. 



The greater length of body, and entirely difi"erent 

 coloration, will distinguish this insect from either dilati- 

 collis or laticollis, the only two known species of the genus 

 with which it agrees in form of thorax.
