242 PHYTOPHAGA. 



Elytra more strongly punctured than the thorax, the punctuation arranged in irregular double rows, the 

 iateratioes finely aoiculate and slightly costate. 

 Hab. Mexico, Yolotepec (SalU). 



The single specimen before me exactly resembles in coloration the spotted variety of 

 Dorvphora mllm, from which the structural characters peculiar to the present genus at 

 once separate it. I know of no species of the latter with which to compare the msect 

 before me.

Hab. Guatemala ^.—Colombia 1 ; Venezuela * 3 ; Peeu (coll. Jacohy). 



I have not seen any other specimens from Guatemala than those contained in the 

 collection of Mr. Baly. 



3. Prosicela brevicollis. 



Oblong-ovate, widened behind, metallic green; terminal joints of the antenme and the palpi black; thorax 

 finely punctured; elytra obsoletely punctate-striate, obscure testaceous, the suture, a longitudinal sub- 

 sutural stripe, a shorter one from the base to the middle, and two oblique stripes at the sides, metallic 

 green. 



HTadtotvL^with a few fine punctures near the clypeus, metallic green ; antennae nearly half the length of 

 the body, the last four joints black, distinctly longer than broad. Thorax short, scarcely twice as oroad as 

 long, metallic green, closely and rather finely punctured, with a small fovea at each side the latter very 

 shghtly rounded and scarcely constricted near the base ; scutellum broadly triangular, dark green. Elytra 

 distinctly widened behind, very obsoletely and rather finely geminately punctate-striate testaceous the 

 suture a longitudinal subsutural stripe from the base to below the middle, a shorter one from the middle 

 of the base to the middle of the elytra, and two other oblique short Hues at some distance from the apex 

 near the side of each elytron obscure greenish or bluish. Underside and legs metallic green. 



Hab. Guatemala, Purula, Sabo (Champion). 



In the elytral pattern and general colour the present species much resembles P. sig- 

 nifera ; it is, however, of different shape, narrower at the base than that species ; the 

 thorax'is much shorter and quite differently punctured, as well as the elytra, the latter 

 further differing in the want of the sutural spots, which are here replaced by a single 

 stripe. The female of the present insect is larger than the male, and the elytra are 

 more strongly punctured. About a dozen specimens were obtained.
