Oblong-ovate, shining, finely punctured ; thorax rounded in front; head much 
narrower than the thorax ; antennz with the third joint long and slender.

thick).

Narrow ; thorax strangulated in front; antenne and legs slender; head as broad 
as the front of the thorax.

Antenne slender, with the first joint as long as the head and thorax, the latter 
not margined; head broader than long; hind legs very long. 
MIRIS Fab. Srenopema Lap. 12 sp. C. dolabratus Linn. Curtis, 701. 
Elongate, narrow; antenne very long, basal joint thickest, porrected, second 
joint longest, slender ; ocelli 0. 
Family 8. (or 10.) LYGAIDA& Westw. (Coreidex p. Leach, 
Steph. Lygeodes Burm. Lygwites and Astemmites p. Lap.) 
LYGAUS Fab. Cimex p. Linn. 1 sp. C. equestris Linn. Curtis, 481. 
Oblong ; wings perfect; ocelli two; legs all slender; last joint of antenne sub- 
fusiform. 
HETEROGASTER Schill. Lyamus Fab. 4sp. C. Urtice F. Curtis, 597. 
Antenne with the basal joint shorter, fourth longest, slightly clavate ; eyes pro- 
minent ; ocelli two; ovipositor arising from the centre of the abdomen ; legs of

C. Echii F. Curtis, 612. 
Ocelli two, fore thighs thickened, toothed ; first joint of antenne shorter, fourth 
longest. 
Obs. The species, which are very numerous, differ in the form of the thorax : 
Pachybrachius Hahn (Icon. Cimic.) has it constricted in the middle; in 
Plinthisus Westw. (P. brevipennis Latr.) it is nearly square, without any 
transverse impression. HH. Schaffer retains Pachymerus (previously em- 
ployed in Coleoptera) for P. Echii, Pini, &c., and Aphanus (P. sabulosus 
Fall.). Burmeister reunites them with the next into a single genus. 
GASTRODES Westw. Puaryeasrer Schill. 1 sp. C. Abietis Linn. 
Fore femora thickened, toothed; females with the last two abdominal segments 
cleft in the middle ; abdomen flattened ; thorax dilated behind. Pz. 92. 22.
