PLAGIODEEA.— LINA. 193 



The scutellum is fulvous, as well as the entire underside, legs, and tarsi ; but the latter 

 have the apex of each joint piceous. In other respects the species is similar to the 

 preceding one, of which it may possibly be only a variety. 



11. Plagiodera flosculosa. (P. ameiventris, Tab. X. fig. 1.) 

 Plagiodera flosculosa, Stal, Diagn. 1860, p. 467; Monogr. Chrys. Amer. p. 306. 



Hab. Mexico, Etla, Capulalpam, Jalapa, Playa Vicente (Salle, Edge). 



The locality of this species was not known to Stal ; the specimens obtained by Herr 

 Hoge agree perfectly with the author's description and with a specimen in Mr. Baly's 

 collection, also from Mexico. From P. ameiventris, which the present species resembles 

 closely in the elytral markings, it may be separated by the crescent-shaped aeneous 

 band of the thorax and of the head. The spots at the elytra are also larger, and 

 leave only narrow spaces of the ground-colour. In all the specimens before me the 

 first five joints of the antennae are testaceous; and in many of them the femora have 

 a metallic spot at the base, or are entirely fulvous. 



In the plate the name of the present species must be substituted instead of that of 

 P. wneiventris. 



12. Plagiodera quadrimaculata. 



Plagiodera quadrimaculata, Jacoby, P. Z. S. 1880, p. 171. 

 Hab. Costa Rica, river Sucio (Rogers). 



This is the largest species of Plagiodera from Central America known to me, and, at 

 the same time, one of the handsomest, being of a black ground-colour, with four red 

 elytral spots. Only a single specimen was obtained by Mr. Eogers.

13. Plagiodera viridipennis. 



Plagiodera viridipennis, Stal, Diagn. 1860, p. 468; Monogr. Chrys. Amer. p. 310 \ 



Hab. Nicaragua, Chontales (Janson). — Beazils 1 . 



I cannot discover any difference of importance to justify the separation of the Nica- 

 raguan forms from StaTs type, which I have before me for comparison.
