MONOTOMIDJE. 



329. Trogosita latens. 



Trogosita latens, Woll., Trans. Ent. Soc. Land. i. 143 (1862). 

 , Id., Cat. Can. Col. 123 (1864). 



Habitat Canarienses (Lanz., Ten., Gom., Hierro), sub cortice EupTior- 

 biarum versus radices prsesertim emortuas latens. 



Detected hitherto only at the Canaries, where, however, we may be 

 pretty sure that it is universal though it happens to have been 

 observed merely in Lanzarote, Teneriffe, Gomera (where it was found 

 by the Messrs. Crotch), and Hierro. It is peculiar to the various 

 Euphorbias, occurring beneath the damp bark (and within the rotten 

 wood) towards the base of the stems and, more often, actually 

 underground at the roots. In such situations I have met with it in 

 Lanzarote, Teneriffe, and Hierro.

Habitat Maderenses (Mad.} et Canarienses (Ten., Gom.), sub quis- 

 quiliis parum rara. 



A European insect which occurs, sparingly, beneath vegetable 

 refuse, both in the Madeiran and Canarian Groups. At the former 

 it has been found in Madeira proper, and at the latter in Teneriffe 

 and Gomera. 



331. Monotoma picipes. 



Monotoma picipes, Hbst., Kdf. v. 24 (1793). 



, Aube, Ann. de la Soc. Ent. de France, vi. 458 (1837). 



congener, Woll, Cat. Mad. Col. 68 (1857). 



- picipes, Id., Cat. Can. Col. 123 (1864). 



Habitat Maderenses (Mad.) et Canarienses (Ten.), sub quisquiliis rara. 



The common European M. picipes is probably about equally dif- 

 fused (and equally scarce), in these Atlantic islands, with the M. spi- 

 nicollis. It has been detected sparingly in Madeira proper, and also 

 in Tenerifte.
