4. Coelomera olivieri. (Tab. XXVII. fig. 9.) 



Testaceous below ; antennae, tibiae, and tarsi black ; head, thorax, and scutellum rufous, the head with two 

 large black spots on the vertex ; elytra obscure purplish, covered with greyish pubescence, extremely 

 closely punctured and rugose. 



Length 6 lines. 



Eab. Guatemala, Purula, Sabo (Champion). 



As the only difference I am able to find between this and the preceding species is 

 the colour of the head and thorax, it is possible that C. olivieri may be but a local 

 variety of C. nigricollis ; there are, however, no intermediate forms before me, and I must 

 look at present upon C. olivieri as representing a distinct species ; from G. lanio, Sahib., 

 and C. cayennensis, Fabr., the colour of the elytra sufficiently distinguish it. 



5. Coelomera godmani. (Tab. xxvil. fig. 10.) 



Coelomera godmani, Jac. P. Z. S. 1879, p. 785 1 . 

 Eab. Nicaragua, Chontales 1 (Belt). 



The colour of the elytra in this species is not black or bluish, but fuscous, the 

 extreme sutural margin being lighter ; the head and thorax have each two large black 

 spots, their ground-colour, as well as that of the underside and femora, is a pale 

 fulvous. C. godmani differs in several respects in regard to colour from C. maculicollis, 

 Clark, and C. binotata, Dej. The two specimens of C. godmani before me differ in no 

 perceptible way from each other. 



6. Coelomera punctaticolHs. (Tab. xxvil. fig. 11.) 



Parallel, obscure testaceous ; antenna?, tibiae, and tarsi black ; head with two black basal spots ; thorax 

 distinctly punctured ; elytra dark fuscous or obscure purplish, minutely granulate and punctured, finely 

 pubescent. 



Length 5-6 lines. 



Head with a few very fine punctures and a longitudinal central groove, the base with two spots ; antennae with 

 the third joint very long, the terminal joints short ; thorax deeply transversely depressed, rather closely 

 and irregularly punctured, testaceous, glabrous ; scutellum testaceous j elytra clothed with fine and short 

 grey pubescence, minutely punctured and granulate. 



Eab. Panama, Volcan de Chiriqui, Bugaba (Champion). 



The only difference of importance I am able to detect between G. pmctaticollis 

 and C. godmani and most of the allied forms consists in the very distinct punctuation 

 of the thorax, and in the obscure testaceous colour of the head, thorax, and under- 

 side. Three specimens before me agree entirely in these particulars ; I am obliged 

 therefore to regard them as specifically distinct ; it is, however, quite possible that 

 C. punctaticolHs is but a local variety of C. olivieri or C. godmani. 



7. Coelomera atro-cserulea. (Tab. XXVIL fig. 12.)
