SCAPHIDIDJE. — CHOLEVA. 13 



— the specimen described by Mr. Spence; the other taken near 

 London. 



Sp. 13. dissimulator. Ovalis, niger, antennis, thoracis longitudine, basi apiceque 



tibiis tarsisque rufo-ferrugineis. (Long. corp. 2 lin.) 

 Ch. dissimulator. Spence. — Ca. dissimulator. Steph. Catal. 73. No. 795. 



Oblong-oval, black, clothed with a dense fulvescent-griseous down ; palpi rufo- 

 ferruginous : antennae as long as the thorax, fuscous, with the two basal joints 

 and the terminal ferruginous : thorax subcraadrate-transverse ; elytra not 

 striated, a single stria near the suture excepted : anterior legs rufo-ferruginous ; 

 posterior black, with the tibiae and tarsi rufo-ferruginous. 



" This insect," says Mr. Spence, from whose valuable monograph of this and the 

 kindred genera I have extracted the leading characters of the species therein 

 described, " affords a striking example of the necessity of attending, in these 

 obscure genera, to minute characters, such as those upon which the families 

 (sections) are here separated. In colour and general appearance it so exactly 

 resembles Ca. clavicornis, that an entomologist not versed in the genus would 

 decidedly pronounce them the same." The form of the thorax, and other 

 characters, render the distinction very evident. 



One of my specimens was captured near London, the other I 

 obtained from Bristol. 



Genus CXXI. — Choleva, Latreille 



Palpi, maxillary with the last joint subulate, conic; labial with the last joint 

 obtuse : antenna* straight subfiliform, longer than the thorax, the club five- 

 jointed, the joints somewhat elongated : thorax with the hinder angles obtuse : 

 elytra oblong, striated : legs rather long, posterior as long as the body ; an- 

 terior femora of similar form in both sexes ; posterior trochanters of the 

 male with a curved tooth on the lower margin, simple in the female; the 

 intermediate tarsi with the basal joint filiform in both sexes; the anterior 

 with the three basal joints dilated in the male. 



Choleva is distinguished externally from Catops by its more 

 elongate form, and by the length and slenderness of its antennse and 

 legs, the obtuse angles of the thorax, and in other less evident 

 characters. 



Sp. 1. angustata. Angustato-oblonga, thorace postice angustiore, medio sub- 



foveolato. (Long. corp. 2^ lin.) 

 Cistela angustata. Fabricius.— Steph. Catal. 74. No. 796. — Ch. oblonga. Sa- 

 moueUe, pi. \.f. 9. 



Narrow-oblong, with an obscure fulvescent pubescence : head black, shining,
