428 PHTTOPHAGA. 



Hab. Guatemala, San Geronimo (Champion), Yzabal (SalU) ; Nicaragua, Granada 

 (Salle). 



Very closely allied to (E. inscripta, but to be separated from that species by the 

 entirely testaceous head and the different shape of the elytral bands, the anterior of 

 which is deeply angulate on each side and at the sutural margin, where it is generally 

 connected with the equally dentate posterior band. As there are eight specimens 

 before me which all differ in the same way from (E. inscripta, I am obliged to consider 

 them as distinct. The elytral bands are often indicated by spots only, but they retain 

 their angulate appearance and are always of & fulvous colour.

(Edionychis biarcuata, Chevr. Col. Mex. 1834, fasc. 3. no. 66 \ 



Hab. Mexico 1 , Cordova (Salle) ; Beitish Honduras (Salle) ; Guatemala, San Gero- 

 nimo (Champion). 



The specimens labelled with the above name and contained in the Salle collection do 

 not quite agree with the description given by Chrevrolat ; this author describes the 

 head as " rougeatre " as well as the thorax ; but in all the specimens before me the 

 former is piceous and the thorax testaceous. The markings of the elytra consist of a 

 black ring at the base, and a semicircular transverse narrow band below the middle, the 

 sutural end of which is connected with another short longitudinal streak within the 

 concave part ; these markings vary in thickness and also in shape ; the breast is black 

 in all the specimens I have for comparison (Chevrolat makes no mention of this), and 

 the fifth to the ninth joints of the antennae are fuscous, the rest testaceous. 



As Chevrolat says that the insect was taken abundantly by M. Salle, I have no doubt 

 about the right determination of this species ; a single specimen only was obtained by 

 Mr. Champion. 



52. (Edionychis proxima. (Tab. XXIV. fig. 19.) 



Pale testaceous ; intermediate joints of the antennae piceous ; thorax impunctate ; elytra extremely closely 

 punctured, a transverse band at the base and another one of a semicircular shape behind the middle, 

 black. 



Length 3 lines. 



Head impunctate, the space between the eyes not broader than the diameter of the latter ; basal and terminal 

 joints of the antennae testaceous, the others piceous ; thorax transverse, at least three times as broad as 

 long, the sides strongly rounded and flattened ; elytra scarcely widened behind, the basilar band not 

 extending to either margin, and obliquely shaped at its inner margin near the scutellum, and another 

 crescent-shaped band extending to the lateral and sutural margins, black. 



Hab. Guatemala, Panzos (Champion). 



At first sight this species seems to be but a variety of (E. biarcuata, Chevr. The 

 following differences will help to distinguish it : — the thorax in (E. proxima is much
