510 PBYTOPHAGA. 



verse band is slightly curved and does not extend to either margin. The four specimens, 

 with the exception of the variety in which the two bands are joined at the sides and 

 are rather broader than in the type, agreeing with each other in the above particulars, 



1 am obliged to treat them as specifically distinct. 



19. Diabrotica godmani. 



Fulvous, the head and breast black ; elytra finely punctured, a broad transverse band at the base, and a 



narrower slightly curved one below the middle, metallic blue. 

 S . Thorax with two or three obsolete depressions, the antennae two thirds the length of the body. 



2 • Thorax without depressions, the elytra more widened behind, the antennas shorter. 

 Length 2£-3£ lines. 



Mai. Panama, Bugaba, Volcan de Chiriqui, Tole (Champion). 



After a careful examination of nearly one hundred specimens I can only come to the 

 conclusion that B. godmani represents a distinct species, although it is undoubtedly 

 very closely allied to B. pulchella, Jacq.-Duv., and D. lucifera, Erichs. In the Panama 

 insect the antennae are entirely fulvous ; in the two last-named species the intermediate 

 and apical joints are dark, and the posterior spot of the elytra is broad and oval and 

 also placed further back than in B. godmani (the corresponding band in our insect 

 being always slightly curved, and its posterior margin concave) ; in general shape also 

 B. godmani is more elongate and parallel, at least in the male. The specimens I look 

 upon as the female of the same species agree perfectly with the others in the markings 

 of the elytra, but differ in the thorax being without impressions, the antennae shorter, 

 and the elytra more widened behind. The foveolate or non-foveolate thorax is generally 

 considered to indicate different species, and which in most cases no doubt holds good, 

 but I think it cannot always be relied upon unless taken in connection with other 

 marks of distinction. I may further add that B. lucifera, if I rightly refer specimens 

 from Peru contained in my collection to Erichson's species, has much more strongly 

 punctured elytra and black tibiae. B. incegualis and B. haroldi, Baly, have the tibiae 

 and tarsi also black.

B. pulchella has been well described by Jacquelin-Duval and Suffrian ; the Central- 

 American specimens before me show no important difference from those from Cuba. 

 The species may be known by the elytra having a large transverse blue band at the
