CANARIAN COLEOPTERA. 493 



which the above structural diagnosis has been compiled, I had regarded 

 it as merely a small and short Anemia {Cheirodes, Dej.), with which 

 in most respects it is identical. But an accurate inspection of its 

 antennae shows them to be, without doubt, only fen- articulate — the 

 third joint being apparently absent*. The few differential characters, 

 of secondary signification, which accompany this primary feature, 

 consist in the shape of the prothorax, which is much more abbreviated, 

 with the hinder angles obsolete (or almost completely rounded off), 

 in its head being narrower and less developed, with the upper divi- 

 sion of the eyes smaller, in its labial palpi being relatively as much 

 elongated as the maxillary pair, and in the fact of the edges of its 

 body being bald (as in 7nost of the Phalerke) instead of ciliated — a 

 character of no shght importance in a sand-burrowing insect. Of 

 the antennal joints, the first one is rather long, slender and subflex- 

 uose at the base, and clavated at the apex, the second shorter but 

 scarcely slenderer, the following four are minute and subequal, and 

 the remainder constitute an abrupt, elongated, quadiiarticulate club 

 — more abrupt at the base than in Anemia. Its wings are largely 

 developed ; and its legs, as in that genus, are eminently fossorial — 

 its tibiae, especially the anterior pair, being powerfully bidentate (and 

 crenulated at theii" base) externally. 



737. Pseudanemia brevicollis, n. sp. 



P. breviter oblonga, rufo-ferruginea, subnitida, supra necnon in limbo 

 fere calva ; capite prothoraceque transversim subscabroso-granu- 

 latis, hoc brevissimo, tenuiter marginato, ad latera necnon ad an- 

 gulos posticos rotundato ; elytris profunde subasperato-2)unctatis 

 (punetis versus suturam obsoletissime subseriatim dispositis), panic 

 transversim rugosis ; pedibus robustissimis, fossoriis, tibiis (prae- 

 sertim anticis) extus fortiter bidentatis. — Long. corp. lin. 1^. 



Habitat Lanzarotam ; in arenosis maritimis juxta Arrecife, Aprili 

 A.D. 1859, exemplar unicum deprehendi. 



A single example of this curious insect was captured by myself in 

 Lanzarote, during April 1859 — on the low sand-hills (or, more pro- 

 perly, on a low sandy ridge) immediately behind the sea-beach, about 

 a mile to the south of Arrecife. 



Genus 276. TRACHYSCELIS. 

 Latreille, Gen. Crust, et Ins. iv. 379 (1809). 



* I find that I am corroborated in this statfiment by a most admirable drawing 

 which has been made for me by Professor Westwood, in which he has exliibited 

 the antenna (with liis usual accuracy) as composed of merely ten articulations.
