14-4 Mr. Crotch's Descriptions uf 



ISCHYliUS, Lac. Moii. Erot., p. 81) (1842). 

 (Type Erot. q^iadrijmndatus, Oliv.) 



This genus, first indicated by Chevrolat in 1836, is now 

 tolerably homogeneous, only the lirst group being at all 

 exceptional. The coarsely granulated eyes distinguish it 

 from all the other New World genera except Epytus.^' The 

 species are numerous and very closely allied. The thorax 

 is rarely margined behind except just round the posterior 

 angles.

 Coincides with my specimens from New Granada. 



10. Ischyrus grapMcus, Lac. Mon. Erot., p. 125 (1842). 



These, as well as the Mexican exponents of this species, 

 appear to Ije a southern form of /. (iuadri])undaiiis with 

 the head more or less rufous.

Oblongus, postice angustior, capite nigro, parce sat pro- 

 funde punctato, thorace rufo-testaceo, lateribus antice 

 rotundatis, punctis discoidalibus 3 nigris; scutello nigro 

 Iffivi ; elytris fulvo-testaceis, vix punctulatis, leviter punc- 

 tato-striatis, fasciis 2 comnumibus nigris, postice denticulatis 

 (1 basali, 1 pone medium) marginem baud attingentibus ; 

 corpore subtus punctidato, rufo-testaceo, epipleuris elytro- 

 rum, lateribus pectoris, pedibusque nigris. L. c. 3^ lin.
