CANAEIAN COLEOPXERA. 247 



scope) ; by its pubescence being a little shorter and yellower, and with 

 a more perceptible tendency to be longitudinally disposed on the 

 elytra ; by its humeral angles being a trifle more rounded-off ; by its 

 eyes being considerably smaller ; and by its Hmbs being usually a 

 shade darker, — the antennae having, also, their basal articulation a 

 little less inflated. 



Hitherto I have seen but three specimens of the X. desectus, — two 

 of which I captured in the region of El Monte in Grand Canary, and 

 the remaining one (which is rather smaller) at Souzal in Teneriffe.

Xyletinus brevis, WoU., Ann. Nat. Hist. (3rd series) vii. 15 (1861). 



Habitat Palmam, mense Maio a.d. 1858 deprehensus. 



The last joint of the maxillary palpi of the present little Xyletinus 

 is rather more evidently scooped-out than in the preceding species, 

 but not so much so as is the case in the following one. In other re- 

 spects it may be known by its small size and short-oval outline, and 

 by its subventricose elytra, which are a good deal rounded at the sides. 

 The only two specimens which I have seen were captured by myself 

 in the Barranco above S*'' Cruz in the island of Palma, during May 

 1858. 



396. Xyletinus excavatus. 



Xyletinus excavatus, Woll, Ann. Nat. Hist. (3rd series) vii. 15 (1861). 



Habitat Canariam Grandem ; mense Aprili a.d. 1858 exemplar uni- 

 cum cepi. 



In the X. excavatus the ultimate joint of the maxiUary palpi is very 

 considerably scooped-out along its oblique apical edge; and, apart from 

 this, it may be known by its comparatively dark hue, more distinctly 

 punctulated prothorax, broader tibiae, and slender feet, the first and 

 second articulations of which are relatively somewhat longer. The 

 only example which I have seen was captured, by myself, in th6 

 south of Grand Canary, during April 1858.
