CEYPTOCEPHALTTS. 45 



shade than that of the thorax, the sutural and lateral margins black (the former broadly, but narrowed 

 near the apex), a broad black stripe on the disk of each elytron runs parallel with the suture, but is 

 abbreviated near the base and apex ; another much shorter stripe is placed near the lateral margin, com- 

 mencing from the base and extending to about half the length of the elytra, where it finishes in a point ; 

 underside and thighs light fulvous, thinly pubescent, inflexed lateral margin of the elytra and the tibiae 

 and tarsi black ; prosternum narrowed at the base, slightly longer than broad, and deeply bidentate at 

 its posterior margin. 

 Var. Dark fulvous ; the thorax without spots. 



Hab. Mexico, Playa Vicente (Salle) ; Guatemala, Yzabal (Salle). 



This handsome species cannot be confounded with any of the first or second groups 

 of SufFrian, to which it is somewhat allied in the colour and markings of its elytra ; 

 in the present species these marks run straight and contrary to the oblique punctured 

 striee which they cut ; the latter also are much finer than in C. ornatus, Fabr., and its 

 allies.

Black, the interrupted anterior and lateral margins, as well as two spots of the thorax and eight spots of the 



elytra (3, 2, 2, 1), yellow ; below black and yellow. 

 Length 1|- line. 



Hob. Mexico 1 , Cuernavaca (Salle) ; Guatemala, Calderas (Champion). 



Only a single specimen has been received from Guatemala, which does not quite agree 

 with Suffrian' s type either in sculpturing or shape of the elytral spots ; the antennae 

 also are entirely black, with the exception of the first two joints ; but as this species 

 is no doubt as variable as many others, further material is necessary to come to a 

 conclusion. Another specimen, from the collection of Mr. Salle, is smaller, and the 

 spots are surrounded by narrow and deep black rings. I have examined the type in 

 the Berlin Museum. 



11. Cryptocephalus patheticus. 



Cryptocephalus patheticus, Suffr. Monogr. vii. p. 10 \ 



Above yellow, the margins of the thorax lighter ; elytra black, with eight partly united yellow spots (3, 2, 2, 1). 

 Length 1^ line. 



Hab. Mexico 1 , Oaxaca (Salle) ; Guatemala, Duenas, Calderas (Champion). 



It is not without doubt that I refer the specimens received from Guatemala to this 

 species. Suffrian has described his from a single specimen ; and there is nothing except 

 the colour of the thorax to distinguish it from C. plagiatus ; the spots of the elytra 

 are here as variable as in other species ; and not even the punctuation of the latter is 

 constant. In some specimens the elytra are black, with no other spots than those 

 along the lateral margin ; the thorax, however, is in no specimen yellow, as Suffrian 

 describes it, but rufous or dark fulvous, which is also the case with a specimen in 

 Dr. Baly's collection and marked "type."
