528 CANARIAN COLEOPTERA. 



the foveee of its head and prothorax more lightly impressed, in its 

 eyes. being less minute, and in its limbs being perceptibly longer, 

 with the antennal club more elongated and perfoliate (the penulti- 

 mate and antepenultimate joints being more loosely connected, and 

 very appreciably larger).

Habitat Teneriffam, a W. D. Crotch semel captus. 



A single specimen of this insect was taken by Dr. Crotch in Tene- 

 riife, during the spring of 1862. I can detect no character to sepa- 

 rate it from the European E. sanguineus — a species which may be 

 known by its, piceous, or dark-chestnut, hue (the limbs, however, being 

 paler or more testaceous), by its head being punctured on either 

 side (though less densely and less coarsely so than in the Karstenii), 

 and by its elytra being rather convex, and rounded laterally (or gra- 

 dually somewhat widened behind). 



Genus 298. ENOPTOSTOMUS (nov. gen.). 

 Schaum* (in hoc opuscule citatus). 



^^Antennoi approximatse, tubercuH frontalis lateribus insertae, maris 

 quatuor, fceminae duobus articulis ultimis incrassatis, ultimo ma- 

 jore. Palpi maxiUares 4-articulati (?), articulo secundo valde ar- 

 cuate, apice parum incrassato, tertio utrinque valde dilatato, semi- 

 lunari, quarto in conum transversum dilatato (ultimis duobus ap- 

 pendice laterali setiformi instructis). Tarsi unguiculis duobus 

 fequalibus. 



" This new genus is allied to Ctenistes and Centrotoma, especially 

 to the former ; the maxillary palpi have lateral setiform appendages 

 as in those genera, but only on the last two joints. 



* The little Pselaphid which forms the type of tlie above genus I consigned 

 recently for description to Dr. Scfiaum, feeling assm-ed that liis long and close 

 attention to the P^cIaphidcB would enable him to point out its distinctive pecu- 

 liarities with greater precision than I should myself be in a ]30sition to do. I 

 would wish therefore to state that the generic and specific diagnoses given above 

 have been communicated by him, for insertion in this Catalogue ; and that I 

 consequently cite them verbatim, without any additional observations of my own 

 (beyond those relating to the hahitaf).
