504 IaSECTA. 



Tbe female of the last-named species protects her youui,^ witli j;:reat care, leadiii!;,^ them about as a hen docs lier 

 chickens. 



Heteroscclis, Latr., is formed Uiv the receptiuii of a speelcs from Cayenne, ha\'Jng the head cylindrical, the 

 anterior tibia: broud and palette-like. 



Ca/iopus, Fabr., as shown by the recent observations of J\I. Alexamlre Lefebvre, is composed of small Soutli 

 American insects, not yet arri\'ed at their full deveiupement, havini^ tlic body lather compre^^cd, and "\"ery con\ex 

 above, concave beneath, and the ocelli, as well as the \ving-.s, wanting;]- 



[The preceding insects form the family Poitalomidtc, Leach; Pcnlatomiies ixml Scutellcrilcs, Laporte ; and 

 iScidaliy Buruieister. The number of genera into which they have been divided by these authors, as well as by 

 Halm, in his Dit Wanzeiuirtigen Insecten, is very p;reatly increased, and has probably been carried too far.*] 



Sometimes the antennae have only four joints, and the body is ordinarily oblong. In some of these the a;itenn;e 

 are liliform or clavate. 



Some exotic species approach the preceding in tlie general form of the body, being rather ovoid than oblong, 

 and are distinguished from all the following by being eitlier very liat, membranous, with the margins very strungly 

 dilated and angular, or by liaving tbe protliorax po.-iteriorly prolonged into a truncated lobe, and the sttrnuni 

 cornuted. Such is 



Tcsseratoiiia, Lejiel and .^erv. Type, J^tl'S-sn /"ij/i//o-sa, Fab. 



Diiiidory Latr., lias similarly -l-jointed antennoe, but the thorax is not posteriorly lobed. {Edcs:,>i oh.yci(ra, 

 mactans, &c.) 



FhUrn, Lep. and Serv., is Cjuite flat and membranous, with the sides of the body dilated and angnlar, the ante- 

 rior extremity forming a flattened, truncated hood, hiding the antennae, which are very short, apparently 3-jointed, 

 and elbowed. [P. corth-ata, a singular Urazihan insect.] 



All tbe others have the body generally oblong, and do not exhibit such characters as the last group. Sonje < f 

 these have the antennae inserted near tbe lateral and superior margin of the head ; the ocelli are close togetlier, 

 or at the same distance apart as they are from the eyes. 



CorcuSy Fab., has the body oval ; the last joint of the antenna ovoid or fusiform, often thicker and not longer 

 than the preceding. C. marginatum; Geoff, [a common English species]. From the proportions of the joints of 

 the antenna; the species may be thus subdivided. Gonocerus, with the third joint of the antennae compressed and 

 angular at the sides,— C. sidcicorniSy vuidkifor, 6^c. ; •Syromaslcs, with the thud joint of the antenna; sin. pie, and 

 b:mger than tlie fourth,— C. 7Ha)-/7?na^w, &c. ; Coi\-u&; \\iththe last joint of the antennae much longer than the 

 fijurth, and compressed,— t'. lurlicunth; &c. 



IJoUii/nu-iiia, Lep. and .-rrv., has the .s.cond and third joints of the antenna.^ plate-like. [Exotic species.] 



Pachijils, Lep. and Serv.. has tbe third joint alone of tliis form. 



A/iisusccUa, Latr., has the antenna; filiform, without dilatation ; some have the posterior tibiswith abroad mem- 

 Iji-ane,— i. mciuhraiiaccus, F., &c. Tlie others, L, vn/gus,Szc., have not, [but the bind femora are often grotesquely 

 thickened. These are exotic species of large size,] Some of the species, with long slender antenna, form my 

 genus Nematupiis. 



.■i/^(/(«. Fab., has the body long and narrowed ; the eyes prominent ; the ocelli close together, and the thorax 

 slightly broader behind. \_A. calcaratus, a rare British species]. 



Leptocorim, Latr. [part of GerrlSy Fab.], has the body long and filiform ; the antenna; and legs are also greally 

 elongated, and the former straight. 



Ncidcsy Latr. {Benjius, Fab.), has the antenna; elbowed. [Small sin-ular insects, three or four species of which 

 occur, but rarely, m this country. C. f/ptdanm-, Linn.] 



We now pass to tbe Geucorisa which have the antenna^ similarly filiform, or thickened at the tips, and 

 4-jointed, but inserted lower than in the preceding ; the ocelli are close to the eyes, and tlie apual mcinbrane of 

 the hemelytra has only four or five nervus. [Tbese form the family Lj/gccid.c] 



Li/gcEus, Fabr., has the head narrower than the thorax, which is narrowed in front,— C. cqncstr/s, Linn. C. 'V- 

 ft'i-KS Linn. ; red, with the head, a spot on the thorax, and two on the hemelytra, black; the wing-covers \Mthont 

 apical membrane, but occasionally this, as well as the wings, is fully developed. [Tbe ocelli are wanting in this 

 species, which forms the type of the genus Piirrhncoris, Fall. ; Plaf;/No/u.s, Scbill. ; or Astcmnia of Lep. and Serv. 

 It is occasionally found in this country.] 



The species with the fore-legs thickened form the genus Pac/n/inerus, Lep. and Serv., but which name having 

 been previously used, must be changed. [The species are very numerous, and form Hahn's genus R/n/- 



pnn.r/n-o.ns.] 



{<:ro':<ii-i^\ Fallen, OpI htfluii' as, Sehill.l S(ddii, Fali., bas tbe heail as broad as the thorax, and often dilated

\\e now arrive at those Ueoairistc luiigilahres with fonr-ioinlrd antenna;, slender, and oi'ten cnpillary at tbe tips. 



Astfinma, Latr. has the second joint of the anteiiuLr ot (.ijiial llnckness, the thorax scarcely broader behind than 

 in front, transverse, quadrate, or cylindrical, tiahia ixill'nujniiv, &c. 



Miris, Fab., resembles Astenmia in the antennae, but has the thorax narrowed in front. 



Capsus, Fab., has the thorax trapezoid, and the second joint of the antennas slender at the base, jiilose and thick 

 at the tip. [C. aicr, and a great number of English species.]
