CANAKIAN COLEOPTERA.

781. Anthicus dimidiatus, n. sp. 



A. gracilis, parum nitidus, piceo-niger, pube minuta fulvo-cinerea 

 demissa vestitus, ubique miniitissime et levissime punctxilatus ; 

 capite parvo, ovali (pone oculos rotundato) ; prothorace postice 

 constricto ; elytris angustis, subparallelis, ad (aiit potius mox pone) 

 basin fascia maxima testacea obliqua (fere ad medium ducta) or- 

 natis ; antennis pedibusque longiusculis, graciliusciilis, pallido-tes- 

 taceis, femoribus plus minus picescentibus. — Long, coi-p. lin. i-1^. 



Habitat in salinis Lanzarotse et Canariae, sed parum rarus ; necnon 

 etiam in Gomera, infra oppidum Hermig-ua, cepit W. D. Crotch. 



The narrow outline and dark surface of this little Anthicus, which 

 has an immense fascia at the base of its subparallel elytra (occupying 

 almost their anterior half), together with its antennae, tibiae, and 

 tarsi, testaceous, and the punctules of its entire surface most minute 

 and lightly impressed, will sufficiently distinguish it. In its small, 

 oval head, basaUy-constricted prothorax, and rather slender and 

 elongated limbs it agrees with the A. htmiilis ; nevertheless all its 

 other characters (of colour, markings, sculpture, and outline) are 

 entirely different from those of that insect ; whilst its total free- 

 dom from a postmedial elytral patch will tend rather to bring it into 

 juxtaposition with the lapidosus. 



The A. dimidiatus I have myself observed only in salt places in 

 Lanzarote and Grand Canary — in the former of which I met with 

 it both at the Salinas in the extreme north of the island, and along 

 the edges of the salt lake of " Januvio " adjoining the south-western 

 coast ; whilst, in the latter, I took a few examples, on the 12th of 

 April 1858, in a precisely similar spot, at Juan Grande. Five speci- 

 mens of it were, however, captured by Dr. Crotch, during the spring 

 of 1862, " below Hermigua " in Gomera. 



782. Anthicus lapidosus, n. sp. 



A. subnitidus, niger, pube grossa argenteo-cinerea sat dense vestitus, 

 ubique profunde et (praesertim in elytris) dense pxmctatus ; capite 

 quadrato ; prothorace antice minus dilatato, postice vix constricto ; 

 elytris ad humeros subrectis, pone basin fascia parva valde obliqua 

 indistincta (interdum aegre observanda sufFusix) subtestacea ornatis ; 



the other, and perfect one (from Lanzarote), I now perceive that (even assuming 

 them both to be females) they could not be identical with'that species ; for (not 

 to mention the colour, which is paler and quite different) its punctation is"al- 

 together a little coarser, its head is longer behind the eyes, its prothorax is wider 

 in front, its pubescence is not quite so minute, its antenna; are relatively some- 

 what slenderer, with their intermediate joints less abbreviated, and its legs are 

 entirely pale. I need scarcely add that if either of these two examples be males, 

 it is still further separated from the instahilis by the simple posterior tibiai of 

 that sex.
