315 Mr. K. G. Blair— yi Revision of 



The species may be separated as follows : — 



J . (4) Head yellow 2. 



2. (3) Underside and limbs testaceous ; elytra sub- 



opaque ; ii'outal excavation of (5 almost 

 closed by liood-lilie projection of the 

 vertex. "(PI. XII. tig. A.) Jlabellata, F. 



3. (2) Underside and limbs in greater part piceous ; 



elytra more nitid ; eyes more approxi- 

 mate ; frontal excavation of ^ bi- 

 foveate, widely open ; vertex only 

 slightly ])rominent femoralis, Lee. 



4. (1) Head black *califurnica, Horn. 



Hemidendroides, Ferr. 



This was proposed as a subgenus of Dendroides, although 

 its affinity with Pyrochroa, as evidenced by the structure of 

 the head and antennae, is closer than with the American 

 genus. From the description it is probable that P. dacidis, 

 Fairm., should be placed here. 



Tlie species are as follows : — 



1 . (4) Elytra unicolorous, testaceous 2. 



2. (3) Head and thorax black. (I'l. XII. lijj;-. o.j ledereri, Ferr. 



3. (2) Head and tliorax concolorous witli elytra .... i^eyroni, Iteiclie. 



4. (1) Elytra black, Avith suture and apex red; head 



and thorax dark red *davtdis, Eairm. 



EuPYRocHKOA, gcu. nov. 



Differs from Pyruchroa in its large size and in the conical 

 genie, which project beyond the eyes. The sides of the 

 prothorax also project strongly just before the base ; the 

 elytra are more explanate behind and more distinctly 

 tricostate. 



There are ordy two described species, which may be 

 separated as follows : — 



Head and thorax shining black; elyti-a briglit red. 



(IM. XII. fig. 0.) insiyniiii, Fairm. 



Head black ; tliurax and elytra dull red, tlie former 



witli black spot on disc and black on sides .... li)iilt(tticollig, I'ic. 



Of these, the latter was described as a variety of the 

 foi'Micr; but M. Pic now agrees with me tliat it is ])robably 

 a good species. 



* Known to mo only i'rom descriplion.
