COELIGETES SUBMETALLICA. 229 



each side in an acute point; the last segment is very long 

 and also deeply excavated through its entire length, the 

 sides ending in a point. 



The female , which is much larger , is probably a va- 

 riety ; of the two males before me , one has the elytra 

 of a dark bluish colour, the other represents a more 

 intermediate stage in which the elytra show traces of 

 the testaceous colour of the female with the exception 

 of the margins which are as in the variety; no other dif- 

 ferences are to be seen between the three specimens , which 

 at first sight seem to represent diflferent species. 



Aenidea sumatrensis ^ n. sp. 



Fulvous ; breast and abdomen black ; thorax nearly im- 

 punctate , biimpressed ; elytra metallic green or blue , very 

 closely punctured , the interstices obsoletely longitudinally 

 costate. — Length 3 — S'/g lines. 



(ƒ . Front of the head excavated , 1^^ joint of the antennae 

 dilated at the apex. 



Q. Antennae and head normal ; thorax more transverse, 

 var. Breast and abdomen entirely fulvous, 



(ƒ. Head impunctate, deeply excavated in front, the 

 excavation divided by a central ridge ; third joint of palpi 

 robust , dilated , the fourth short , acute ; antennae two 

 thirds the length of the body, the second joint very short, 

 third longer than the fourth and as long as the seventh , 

 the latter dilated at the apex , obliquely shaped at the 

 same place ; thorax subquadrate , slightly broader than long, 

 the sides nearly straight, slightly narrowed below the 

 middle , surface with a deep fovea at each side , impunc- 

 tate ; angles slightly tuberculate , each tubercle with a 

 single bristle-like hair ; scutellum black ; elytra parallel , 

 metallic green or blue, closely punctured, the punctures 

 arranged in irregular double or treble rows , the intersti-
