THROSCID.E. 189 



by myself, during August 1855, by beating rank vegetation in the 

 north of Madeira proper about a third of the way up the Eibeiro 

 de Sao Jorge. 



Fam. 37. THROSCID.E. 



Genus 170. THROSCUS. 

 Latreille, Prec. des Caract. Gen. des Ins. 42 (1796). 



I. Oculi integri. 



537. Throscus latiusculus. 

 Throscus latiusculus, Woll., Append, huj. op. 30. 



Habitat Canarienses (Hierro), a DD. Crotch sat copiose deprehensus. 



Captured by the Messrs. Crotch in Hierro, the most western of the 

 Canarian islands, where they obtained it rather abundantly. 



538. Throscus elongatulus. 



Throscus integer, Woll., Cat. Can. Col [sed vix Cat. Mad. Col.] 209 



(1864). 

 elongatulus, Id., Append, huj. op. 30. 



Habitat Canarienses (Ten., Gom., Palma), in sylvaticis editioribus 

 rarissimus. 



Likewise Canarian, occurring sparingly under dead sticks and 

 rubbish in the sylvan districts of a rather high elevation. A tolerable 

 series of it was taken in Gomera, during the summer of 1864, by 

 the Messrs. Crotch ; and it is from their specimens that my diagnosis, 

 given in the Appendix, has been compiled. I had myself, however, 

 met with a few examples previously, both in Teneriffe and Palm a, 

 which I have little doubt are conspecific with the Gomeran ones, 

 even though it is true that a Palman individual which is now before 

 me does not perfectly accord with the latter. At any rate, since it 

 is the Gomeran insect that I have taken as the type of the present 

 species, I need scarcely add that if future material should prove the 

 Teneriffan and Palman Throscus to be distinct (which I consider im- 

 probable) the name elongatulus must of course apply to the former. 



The T. elongatulus closely resembles the Madeiran T. integer, of 

 which I am far from satisfied that it is more than a geographical 

 state ; but the characters, small though they be (even whilst constant), 

 which distinguish it therefrom have been fully pointed out in the 

 Appendix.
