228 COELIGETES. 



9. Abdominal segments normal, the fifth emarginate at 

 the apex. 



This genus will enter the group of Platyxanthinae (the 

 26*^1 of Chapuis) from all genera of which it differs by the 

 narrow transverse thorax and the want of depressions at 

 the upper surface of the latter. 



Coeligetes submetallica, n. sp. 



Fulvous; head and thorax rather remotely but distinctly 

 punctured ; elytra metalhc dark purplish or aeneous , clo- 

 sely punctured , the interstices finely rugose. — Length 

 3i/2-4'/2 lines. 



var. Elytra testaceous, the sutural and lateral margin 

 metallic purplish. 



cf. Head finely punctured near the eyes, transversely 

 grooved between the latter; frontal tubercles trigonate, 

 nearly contiguous ; lower part of face testaceous ; antennae 

 more than half the length of the body, testaceous, the 

 two terminal joints obscure fuscous; thorax reddish ful- 

 vous, like the head, the anterior margin slightly concave, 

 the sides somewhat rounded and narrowly margined , the 

 angles produced in a short tubercle , the posterior ones 

 furnished with a single bristle-like hair; surface rather 

 convex , irregularly and remotely punctured ; scutellum 

 broad , its apex obtuse , black ; elytra rather convex , clo- 

 sely and more distinctly punctured than the thorax , the 

 interstices irregularly transversely and longitudinally ru- 

 gose ; underside fulvous ; legs paler , the tibiae with a black- 

 ish streak at their outer side. 



var. (9). Larger and more robust , elytra testaceous , the 

 lateral margin rather broadly, the sutural one very nar- 

 rowly purplish blue as well as the extreme base. 



The structure of the abdomen in the male of this spe- 

 cies is very curious; the fourth segment is furnished with 

 a small but deep cavity, the anterior margin of which is 

 distinctly raised , while the posterior one is produced at
