TOMICID^E. 



the Madeiran Group, where I obtained it rather abundantly, during 

 June 1850, by beating the dense masses of wormwood (Artemisia 

 argentea, Herit.) which clothe certain parts of that singular little 

 island. But whether it was actually attached to the wormwood, or 

 had come out of the dead branches of some Euphorbia or other 

 plant, I am unable to say.

Habitat Canarienses (Ten., Gom.), in Euphorbiis emortuis minus 

 frequens. 



A most minute Canarian Liparthrum, which has been observed 

 hitherto only in the dead Euphorbias of Teneriffe and Gomera. It 

 was first detected by the Eev. R. T. Lowe in the former island, near 

 Garachico ; and a considerable series is now before me which was 

 captured, likewise in Teneriffe, by the Messrs. Crotch, during the 

 summer of 1864. We may, however, expect it to occur more gene- 

 rally throughout the Group.

Habitat Canarienses (Gom.}, in ramulis Euphorbiarum emortuis a 

 DD. Crotch sat copiose lectum. 



This curious little insect, so remarkable for the enlarged process, 

 or nodule, into which the raised second interstice of each elytron is 

 backwardly produced behind, was captured abundantly by the Messrs. 

 Crotch in Gomera, during their late Canarian expedition. According 

 to their report, it was found within the dead twigs of one of the 

 " sweet " Euphorbias (perhaps the E. balsamifera, or the reyis- 

 Jubce).
