Mr. Spence’s Monograph of the Genus Choleva. 
pleura* inflexa, post-pectoris abdominisque latera 
amplectens, concava, interdum plana, sublineari- 
lanceolata, a basi ad apicem Elytrorum feré exten- 
dens, vix marginata, rarissimé canaliculo marginali 
instructa. 
Ale transverse plicatz, hyaline, dimidiato-ovate, cor- 
pore longiores, neuris tribus vel quatuor validiusculis. 
Pectus naviculare : sternum acuté carinatum, concavum, 
sive segmento circuli dempto, inter coxas pedum an- 
ticorum latens. 
Post-pectus ( Pectus Il'ig.) subgibbosum abdominis lon- 
gitudine. Peristethium subplaniusculum (est ubi in 
medio acute carinatum) acumine longo spectante 
inter coxas intermedias terminatum. Scapularia (Sca- 
pula Knoch) triangulari-trapeziformia. Mesostethium 
subcordato-quadratum, gibbosiusculum, interdum 
processu apice bifido, inter coxas posticas delitescente 
.terminatum. Parapleure angustissim? triangulares, 
cum pleuris in carinulam obtusangulam longitudi- 
naliter coalitz. | 
Pedes cursorii, subelongati, graciles, antici intermediis, - 
intermedii posticis breviores. Cove approximate : 
anteriores dimidiato-conic®, femoribus crassiores et 
breviores; postice (Meriea Knoch) transverse li- 
.neares supra planiuscule, subtus convex, intus cave. - 
* A term happily suggested by Mr. Kirby to designate the deflexed lateral margin of 
the elytra so conspicuous in Blaps, Cychrus, &c. and, if I mistake not, often supplying 
very valuable subsidiary generie characters. 
+ I adopt Knoch's very convenient suggestion, and apply the term anteriores when 
the four fore feet, posteriores when the four hind feet, are understood ; using antici, me- 
dii, and postici for the two fore, two middle, and two hind feet, respectively.
