Atlantic Coleoptera. 265 
for this insect must be changed, that name having been 
pre-occupied by Perris (in the ‘ Ann. de la Soc. Linn. de 
Lyon,’ sér. 2, iv. 147) for a Rhyncolus from the south of 
France; and, having therefore at the time proposed that 
of pinipotens instead, the synonymy of the species will 
stand as follows : 
Rhyncolus pinipotens. 
Rhynecolus crassirostris, Woll. [nee Perris], Trans. Ent. 
Soc. Lond. v. 367, pl. 18, f. 3 (1861); Id., Cat. Can. 
Col. 270 (1864) ; Id., Col. Atl. 252 (1865). Rhyncolus 
pinipotens, Id., Col. Hesp. (Append.) 275 (1867). 
Hab.—Canarienses (Can.); lignum antiquum Pini 
canariensis in montibus parce destruens. 
p- 259 (genus CavLorrvpis). 
After species 726, add:— 
Caulotrupis pyricollis, n. sp. 
C. ellipticus, nigro-eneus (rarius eeneus), subnitidus ; 
prothorace pyriformi-conico, fere impunctato (sc. punc- 
tulis levissimis parce irrorato); elytris obsolete et 
levissime subpunctulato- striatis, stris postice paulo 
distinctioribus, antice evanescentibus; antennis brevius- 
culis, ferrugineis, pedibus rufo-piceis. 
Long. corp. lin. 14-2. 
Hab.—Maderenses (Mad.) ; sub cortice, truncis humi 
jacentibus, lignoque recenter secto, in castanetis longe 
supra urbem Funchalensem (presertim imter 1600’ et 
2000’ s. m.), vulgaris. 
Obs.—Species C. conicolli affinis, sed nisi fallor dis- 
tincta ; differt corpore plus minus evidenter angustiore 
aut magis oblongo-elliptico (nec obpyriformi), necnon 
minus enescenti minusque nitido, prothorace sublongiore, 
subampliore, minus argute conico, elytris postice minus 
striato-ineequalibus. 
I cannot feel altogether certain that this Cawlotrupis is 
more than an extreme variety, or race, of the C. conicollis, 
—for the Caulotrupides appear to be eminently hable to 
slight alterations, both in outline and sculpture, accord- 
ing to the exact locality in which they severally occur.
