430 CANARIAN COLEOPTERA. 



punctulated surface of this European Scymnus, in conjunction with its 

 pallid limbs, will sufficiently characterize it- It occurs in the Ma- 

 deiran Group, and there can be little doubt that it is universal at 

 the Canaries, though hitherto it does not happen to have been noticed 

 in Palma. I have, however, myself taken it in Lanzarote ; at Agua 

 Bueyes and in the Rio Palmas of Fuerteventura ; in Grand Canary ; 

 near the Puerto Orotava in Teneriffe ; and close to Valverde in Hierro. 

 In Gomera it was captured both by Mr. Gray and Dr. Crotch, the 

 former of whom found it in the valley above San Sebastian.

Habitat insulas Canarienses, in Gomera sola adhuc hand detectus. 



There can be little doubt that this common European insect, which 

 is universal throughout the Madeiran Group, and which has been 

 recorded from the Azores, is imiversal also at the Canaries — though 

 hitherto it does not happen to have been observed in Gomera. But 

 in Lanzarote, Fuerteventura, Grand Canary, Teneriffe, and Hierro I 

 have myself captured it ; and it was found in Palma and Hierro by 

 Mr. Gray. In Teneriffe it was met with likewise by Dr. Crotch.
