UYMEMOPTERA. 58 Q 



wliich resitles in tlie card-nests of one of tbc wasps of South America, and wliich Reaumur considers as the 

 female of this wasj). 



JJir/iinifSy Dalm., has the bead deeply bifid and prolonged in front, as well as the niandiijles. [D. ejcavatns, 

 Dalni., an African species.] 



Palmon, Dalm., composed of species found in copal, has tlie antennae terminated by three thick joints, and the 

 ovipositor exserted. 



LeucospiJi, Fab., has the abdomen applied ajjainst the hind part of the thorax, rounded behind, with the ovi- 

 positor curved over the back. The female of L. dorsigera places its ^^gs in the nests of Mason Bees ; that of L. 

 giilds oviposits in Wasps' nests. 



The others have the antenna; mostly only from 5- to 9-jointed, with the hind thi;,^hs obloug-, and the tiltias 

 straight. 



E/icharis, Latr., with straiL^ht 12-jointed antenufe, and, according; to Latreille, without any vestige of palpi. 



Thoracantha, Latr., Urazilian insects, with the scutellum extended over the abdomen. 



The remainder have the antenna at least 9-jointed, simple, and elbowed, and scutellum small. 



Of those which have the antennae not inserted close to the mouth, some have the abdomen nearly ovoid, com- 

 pressed at the sides, and the ovipositor mostly exserted. 



AgaoHy Dalm., has the head very larf;;e and flat, and the basal joint trianjjular. [A. paradoxus, Dalm,, from 

 Sierra Leone, closely allied to the insect which is used in caprificatlon.] 



Enri/timtff, UVv^., lias the male antenna; nodose and verticillated, and the ovipositor short. [Numerous small 

 British species. 



Miscocampns, Latr. [Tori/mus, Dalm., or more properly Callimome, Spinola], has the antennae not verticillated, 

 and the ovipositor long. One species is parasitic upon the Cynips of the Rose bedeguar, [a very numerous British 

 genus]. 



The others have the abdomen flat abuve, triangular and pointed in the females, or subcordate or suborbicular. 

 The ovijiositor is mostly concealed. 



In somt: of lliese, the stigmal branch arises at a distance from the union of the costal nerve with the costa of the 

 fore wings. 



Per'dainpus, Latr., has the abilomen short and cordate, and not prolonged, with the scutelium thick and promi- 

 nent. [Several British species.] 



Ptfroiruilus, Latr., has the thnrax short, with the collar not narrowed in front, and the abdomen of the females 

 terminated in a conical point. [A very numerous genus.] 



Cleoniintns, Latr., has the collar elongated and narrowed in front; the abdomen is also niuch longer. [C. de- 

 pressiu, Latr., a rare British species, &c.] 



In others, tlie stigmal branch arises from the union of the costal nerve with the costa ; the middle legs are longest, 

 with a long spur at the ape.x of the tibiio. 



Eupelmi/.s, Dalm. [has the ovipositor exserted], and the basa! joint of the middle tarsi broad and ciliated, and 

 the stigmal branch removed from the costal nerve. 



Ennjrius, Latr., has the stigmal branch arising from the apex of the costal nerve; the club of the antennre is 

 compressed and truncate. [A very numerous genus, of minute species.] 



.'^palanqia, Latr., differs froiii all the preceding in having the antenna? inserted quite close to the mouth. 

 EidophiiSy Geof. {Enlcdon, Dahn.), has the anteiin;e from 4- to S-jointed, those of [some] males being branched. 

 [A very extensive genus.] 



[This family, Chalcididce, lias recently received much attention, and a great number of additional 

 genera have been established, especially by Spinola, Dalman, Walker, Esenbeck, Ilaliday, and my- 

 self. Those found in tills country are described in the generic synopsis of my "Modern Classih- 

 cation."] 



The fifth trihc, Oxyuri, resembles the preceding in the absence of nerves in the lower ivings, l)ut 



the abdomen of the females is terminated by a tubular ovi])ositor of a conical form, and either internal, 



exsertile' from the anus like a sting, or externa!, and forming a kind of tail or terminal point. The 



antennae are from 10- to 15-jointed, and either filiform or rather thickened to the tips, or clavate in 



the females. The maxillary palpi in many are long and pendente We reunite the different genera of 



which it is composed to that of 



Bethylus, Latr. & Fabr. 



Their habits are probahly the same as those of the Chalcidites, but as the majority of these insects 



are found upon the ground or low plants, I conjecture that their larvse hve in the earth. 



Some have the wings furnished with veins and cells, and a portion of these have the antenna; inserted near the 

 mouth. 



Dryinus, Latr. ( Gonafopvs, King), has the antenna straight, 10-jointed, in both sexes ; the thorax binodose, and 

 the fore tarsi terminated [in the females only] by two large reflexed hooks. Some females are apterous. [See the 

 monographs of Esenbeck and Walker.] 



Aiitco)i, Jur., has only 10-jninted antpim;e, at least in the m^iles, but the thorax is continuous, and the tarsi are 

 terminated [in the males only] by ordiinry-sized claws.
