192 PHYTOPHAGA. 



8. Plagiodera uniformis. . 



Kotundate, convex, entirely testaceous ; last six joints of the antenna black ; thorax closely punctured at the 

 sides, remotely at the disk ; elytra strongly punctate-stnate. 



HTaffl«out central groove; antennae as long as the thorax, the first five joints <*»^J£*£ 

 black and transverse; thorax as broad at the base as the elytra, closely punctured ^ the sides the 

 disk with a few punctures only ; scutellum testaceous ; elytra rather convex from base to the midcue, 

 strongly punctate-striate, the rows more distantly placed near the suture than at the sides. .Legs 

 testaceous. 



Hah. Mexico (SallS, coll.Baly); Guatemala, Chacoj, San Juan, Panima {Champion). 



The uniform coloration and strong punctuation of this species form the principal 

 distinguishing characters. Four specimens only were obtained by Mr. Champion; 

 another, in the collection of Mr. Baly, is of a rather more ovate and less rounded shape, 

 but does not differ in other respects. 



9. Plagiodera atritarsis. 



Plagiodera atritarsis, Stal, Monogr. Chrys. Amer. p. 298 \ 



Hob. Mexico, Oaxaca {SallS) ; Guatemala, Zapote, Duenas, San Geronimo {Cham- 

 pion, Salle). — Venezuela, Caracas \ 



As indicated above, the country of this species, as given by Stal, is Venezuela ; in 

 the collection of Mr. Baly the locality is given as Mexico and Guatemala, the specimen 

 contained in it having been named by Stal himself, and agreeing perfectly with several 

 before me from Guatemala &c. The species is of a light fulvous or testaceous colour, 

 with the suture narrowly and the scutellum entirely black ; the last six joints of the 

 antenna? are black and transverse, and forming a club ; the closely and finely punctured 

 elytra show traces of smooth longitudinal striee, which are impunctate. The underside 

 is generally of the same colour as above ; but several specimens from Guatemala are 

 nearly entirely black below, in which respect the specimens seem almost identical 

 with P. cerea, Stal, which may be only a variety of P. atritarsis. 



10. Plagiodera unicolor. 



Ovate, rather convex, subparallel, fulvous ; last four joints of the antennae black ; thorax finely punctured ; 



elytra punctate-striate near the suture, with two or three smooth longitudinal interspaces. 

 Length 3g lines. 



Hah. Mexico, Chiapas {SalU). 



Although the present species, of which I have a single example for comparison, is no 

 doubt closely allied to P. atritarsis, I believe it to be distinct from the latter on account 

 of the following differences :— The antenna? have the first seven joints of a fulvous colour, 

 instead of five as in the other species ; the thorax of the present one is not so narrowed 

 in front, and the sides are more rounded, while they are nearly straight in P. atritarsis.
