the genus Criocephalus. 155 



N.B. — I have not been able to examine the labrum in 

 C. exoticus and C. tibetanus, and one or both may therefore 

 prove not to belong to this division. Neither the hairs on 

 the eyes nor the lobing of the tarsi can be used as sectional 

 characters as there are intermediate conditions of both of 

 them. But in this section the ocular setae are usually 

 short, and the basal lobes short. 



Criocephalus pinetorum, Woll.

Wollaston first fell into the double error of considering 

 the sexes of C. pinetorum to be different species and of 

 determining the female to be C. rusticus. This was not 

 recognized by him in revising the work in 1865, and being 

 then baffled to distinguish the C. pinetorum he sank the 

 species as being merely C. rusticus, from which however it 

 is totally distinct. This does not complete the sum of 

 Wollaston's confusion ; for he considered the Madeiran C. 

 rusticus to be the same, though he noticed the different 

 habitat in the two islands. The insect found about 

 Funchal in Madeira in connection with the introduced, 

 planted, conifers is really the C. rusticus of authors, while 

 the C. rusticus of Wollaston Coll. Atlant. (nee auctt.), 

 found in the native pinals of the Canary Islands, is 

 the female of C. pinetorum, Woll., and is a quite distinct, 

 precinctive species. As Wollaston found the two together 

 in the Canaries it appears remarkable that he should not 

 have considered them to be the sexes of one and the same 

 species. Probably he suspected them to be so, but not 

 having detected the characters that distinguish the female 

 from C. rusticus and C. ferus (which at that time were 

 generally confounded in collections), he finally came to the 

 erroneous conclusion that all were one species. Hence 

 this good species has since been lost sight of. Bedel how- 

 ever suspected some error ; and in placing the name as a 

 synonym of G, rusticus added a note of interrogation. 



This species has the eyes bare {%. e. with extremely short 

 setse between the facets) and the fourth joint of the tarsi 

 intermediate between that of C. rusticus and C. ferus. 

 The sexes are very different, and hence Wollaston supposed
