16 PHYTOPHAGA. 



all respects with Lacordaire's description ; the other two, however, show some differences 

 in the sculpturing of the thorax, which is not smooth as in the typical species, but 

 finely transversely wrinkled ; the femora also are much less robust and shorter than 

 those of C. smaragdina. As these, however, are the only differences between the 

 specimens, I am inclined to regard the two aberrant forms as the females. 



9. Crioceris gemmans. 



Crioceris gemnians, Guer. Ic. Regn. Anim. iii. p. 261 ; Lacord. Mon. p. 554. 

 Crioceris superba, Dej. Cat. 3rd ed. 



Hab. Mexico. 



10. Crioceris nullicedo. 



Crioceris nullicedo, Lacord. Mon. p. 556. 

 Hab. Mexico; Guatemala, Zapote (Champion) ; Costa Eica, E. Sucio (Rogers). 



Seems to be a rather common species in Guatemala, to judge by the many specimens 

 received from there. 



Var. callizona. 



Crioceris callizona, Clark, Cat. Phyt. App. p. 64. 

 Hab. Mexico; Guatemala, Zapote (Champion) ; Costa Eica. 



Although this insect is considered by Clark a distinct species, I believe it to be only 

 a colour variety of C. nullicedo. It has been sent rather frequently in company with 

 and from the same locality as C. nullicedo, from which it does not differ except in 

 coloration, being violaceous instead of green, and in having the elytral bands only 

 indicated. Clark gives as his reason for considering it a distinct species, because the 

 head of C. nullicedo is smooth or impunctate, agreeing with Lacordaire's description, 

 while in Clark's species the same part is punctured. I find that all the true 

 C. nullicedo are sparingly but distinctly punctured, as is the case with C. gemmans, also 

 described by Lacordaire as having a smooth head. Clark's description was drawn from 

 a single specimen. The thorax is also rather variable in the specimens before me, 

 and the hinder femora differ according to the sex ; moreover intermediate forms have 

 come under my notice, and therefore I cannot admit C. callizona as a good species. 



11. Crioceris intermedia. (Tab. I. fig. 16.) 



Metallic green ; abdomen more or less fulvous ; elytra with two broad transverse copper- coloured bands, one 



before, the other behind the middle. 

 Var. The anterior elytral band sending off a branch of the same colour to the base of the elytra. 

 Length 5 lines. 



Hab. Nicaragua, Chontales (Belt) ; Costa Eica (v. Patten). 



This species seems to be intermediate between C. gemmans and C. nullicedo ; it is
