'09O LXSECTA. 



Beihjilliif;, Latr. [Omalns, Jur.), has the autennrr; cltiowe'l, 13-jointod, in both sr-^es, the head llattened, iiiid the 

 prothorax elon;2;ated and suhtriaiiLCular, 



Another portion h.i.s tlic ;nil(iiii:i' 13- to l:>-jointed, and inserted near the middle of tlie face. 



Vroctoiriipes, Lntr. [('uilr'is. Jar.), have them 13-jointed and strai^^ht in both sexes. [Numerous British sjte- 

 cies, monographed by Haliday.] 



llelortLS, has the antennae distinctly rlbowed, and 15-jointed; tlie first joint of the abdomen forms a sudd-n 

 long: peduncle. [II. a/toinalipes, a singular British insect.] 



Befi/ta and Cin.-tns, Jur., have the antennje 14- or 15-join1ed, filiform in the males, and thicker at the ti[( in tlie 

 females. 



The other Oxynri have neitlicr cells imr bracliial or basal nerves. Some of these have the antenn;e inserted In 

 the forehead. These are 



Diapria, Latr. {P.u/i/.\, Jar.), wlach has no cell in the wini^-'s. The males have 1-1-, and the tVmales 15-jointed 

 antennse. 



Others have the antennse inserted near the mouth. 



Ccraphron, Jnr., has a radial cell, the maxillary palpi ]irominent, the anterniee filiform and H-jointed, and the 

 abdomen ovate-conic. 



Spdrasion, Latr., is similar to Ceraplirnn in the radial eel! and maxillary jialpi, but \iitli the anteiinaj 1'2-joiuted 

 in both sexes- 



The two following subgenera differ from Sparasion in ha\ing the palpi very short, and not exserted or pendent. 



Te/ea.-i, Latr. having 12-jointed antenncc. 



Sceiio, Latr., with lO-jolnted antennae. 



In the terminal subgenus Plufi/gasfer, Latr., the radial cell is wantinLr, the antennae in botli sexes are 10-jointed, 

 the first and third being very elongated ; the palpi are very short, and the abdomen spatulate. I refer to this sub- 

 genus the Pa-Hus Boscii, Jurine, a very curious insect, in which the basal segment of the abdomen supports a 

 strons: horn, which extends over the back of the head and thorax, and which, accordino; to Lecleix de Laval, is a 

 tube for the oviposilor% [This opinion is certainly incorrect. The insect is remarkable for its habits, and has been 

 described by the Canon Schmidberger, under the name of the Paradoxical Pear-fly. Sec KoUar, Obiiu.r. Ins., 

 translated by Miss Loudon.] The species is very minute, and black. 



[See the monographs of Platyi!:aster, and several of the yireceding genera, published liy Mr. AYalker in the Ento- 

 moloifical Maijn:inc,n\ which work, as well as in Esenbeck's work ori these families, \arious additional ;^^enera 

 are described.] 



The sixth tribe, C'liRYS-inr:--;, Latr., like the three preceding tribes, Iiavc the hind ■s\"ingL^ not veined, 

 hut the ovipositor is formed hy the terminal segments of the ahilomcn, like the sliding tubes of a tele- 

 scope, and terminati'd by a small sting. The abdomen, Avhicli in the female ajipears to be foimied nf 

 only three or four segments, is vaulted or llattencd lieneath, and cajjulde of being foldeil against tlie 

 breast, vi'hen the insect assumes the ajjpearanee of a hall, 'i'his tribe i:^ eoni[iuh,cd of the genus 



CdRYSis, Linn., — 

 Which in the richness of their colotirs vie \vitli the Humming-lnrds ; hence they have heen termed 

 Golden-tailed Flies. They may he observed walking, Init in a constant agitation and ■with great aglliry, 

 upon walls and palings exposed to the heat of the ^nn. They are aUt) found upon llowers. The hody 

 is elongated, and covered \vi(li a solid fskiu ; the anteniue. filil'orni, elbowed, and vihrafile ; the maxillary 

 palpi long and 5-jointed, the labial 3-jointcd ; the abdomen in the niajnrity is semi-oval, truncated ac 

 the liase, so as to appear sessile; the terminal segment has id^len a dee[i row of impressed dots, and 

 the apex is denticulated. They deposit llieir eggs in the nests of Solitary Ma^on-Iices, or other 

 llymenoptera, their larvae destroying those of these in^ccts. 



Parriopcs, dilfers from the rest in having the maxilla and lower lip very long, forming a probuscis. P. cnrncc-^ 

 a continental species, places its eggs in the nest of Bemhcx i-o.-<1rata. 



The others have not an elonirated proboscis. 



In some the thorax is not narrowed in front, the anteniue scini-cnate, and only with three segments, ar. in 



C/in/su proper, which may be tlin.s divided ; — 



Those with the four palpi equal, and ilir labium deeply notched, form the genus S/Ubiim, Spin., to %vhich vv'o may 

 unite Eucf>r<jeirs, Latr.,— [and Pi/ria, St. Fargeati]. Those with the maxillary palpi much longer than the labial, 

 with the labium notched, and the abdomen rounded at the tip, form the genus }fefl>i>:!<ntiii. Those with the palpi 

 as in Hedychrum, but with the labium rounded and entire, form the genera Elampim and C/in/si-s; the lir^t of 

 wddch has the nian{libles with two tei-th within, and the abdomen entire at the tip, and the second has the man- 

 dibles with one tooth within, and the extremity of the abdomen is spined, and has a row of deep spots. To 

 this last group belon^-s C 'ujnihi, Linn., the ronmionest species in Europe, of a blue colour, with the abdomen 

 fiery-red. 



Clfp1cs,1jx\T., has the mandibles short and toothed, and the thorax narrov/ed in front; the male lias the 

 abdomen 5-, and the female 4-juinted.
