CANARIAN COLEOrTEKA. 413 



very obscure) strigse. Its liead is a Kttle darker (or more rufescent) 

 than the prothorax, and the prothorax (which is coarsely bordered 

 at the sides) than the elytra — which last are impressed (particularly 

 behind) with a rather evident sutural stria.

Habitat in Teneriffa et Gomera, in ilia a Dom. Crotch sed in hac a

The brownish -testaceous hue and coarsely sculptured surface of 

 this rather insignificant Lonc/itarsus, which has its prothorax trans- 

 verse-quadrate (the sides being nearly straight), and its elytral punc- 

 tures somewhat large and closely packed together and with a slight 

 tendency to be arranged in longitudinal rows, will sufficiently distin- 

 guish it from its aUies. M. Allard states concerning it, " il a beau- 

 coup d' analogic avec la T. brunniceps, mihi, dont il differe principale- 

 ment en ce qu'il est ferrugineux en dessous et non pas noir." A 

 single specimen of it was taken by Mr. Gray, near San Sebastian, in 

 Gomera, at the beginning of February 1858 ; a second (which differs, 

 however, in being rather paler, and in having its prothorax perhaps 

 a trifle less abbreviated and with the lateral margin less thickened, 

 but which I believe to be an immature example of the nubigena) was 

 found by Dr. Crotch in Teneriffe, during the spring of 1862 ; and I 

 myself met with a third, in Teneriffe, during May of 1859*. It 

 occurs likewise, though sparingly, in Madeira.

Habitat Lanzarotam borealem, in graminosis herbidis circa oppi- 

 dum Haria, tempore vernali hand infrequens. 



The only region in these islands in which the European L. dorsalis 

 has (so far as I am aware) been observed is the north of Lanzarote 

 — where it was captured, during January 1858, by Mr. Gray and 

 myself (and subsequently, by myself, in March of 1859), around 

 Haria. The dark colour of its head, broad sutural stripe, and two 



* The last of these is of a rather darker hue, and lias the hinder disc of each 

 elytron, as well as its two posterior femora, piceous.
