the genus Qrioeephalus. 157 



and pubescence of the gular area are very different. In 

 G. rusticus the tarsi have the third joint divided almost to 

 the base, and the seta? on the eyes are very conspicuous ; 

 while in G. f erics the eyes appear to be bare, and the tarsal 

 lobes are less perfect. 



The species is extra ndinarily variable in size, some 

 specimens of the female being quite three times as long as 

 the small males, and are broad in proportion ; so that it 

 would take twenty or thirty of the small males to make up 

 the bulk of one of the largest females. There are also 

 some variations in the proportions of certain parts of the 

 body, so that I at first thought there to be more than one 

 species under the name of G. ferns. A series from Algeria 

 kindly communicated to me by M. Bedel has convinced 

 me that this is not the case. There is also great variation 

 in size independent of sex, some of the females being six 

 or eight times the bulk of other individuals of the same 

 sex. The distance between the eyes on the under-surface 

 of the head varies somewhat, and correlative with it there 

 is a difference in the sculpture of the gular area. I 

 distinguish the following variety with some doubt, having 

 seen only two examples. 



C. FERUS, var. n. HISPANICTJS. 



Minor, praesertim angustior, elytris fere ecoatatis. Long. £ 14, 

 $ 16 mm. ; lat. £ $ 4 mm. 



I have seen only a single pair found at Navalperal in 

 the Guadarrama range by Mr. Champion. They were in 

 company with Nothorhina muricata and are damaged by 

 turpentine. There is a slightly larger specimen from the 

 same locality in the Oberthtir collection. The sculpture 

 of the gular area appears to be more rugose and less definite 

 than in other forms of C.ferus, but the distinction in this 

 respect from certain other Spanish examples is not great. 

 It would take eight such females to attain the mass of a 

 well-developed female of G. ferns. 



G. femes has a very wide distribution, but is rarely met 

 with, and then usually only in one or two individuals.
