Uromelia, Kapala, Lirata, Tetramelia, Stilbura, Psilogaster, Chalcura, 
and Orasema, mostly by forms already described. 
The next sub-family, or the Perilampince, is represented by several 
forms, possibly undescribed. 
The Eurytomince are well represented, and I find species agreeing with 
our North American genera Isosoma, Eurytoma, Decatoma, Rileya, &c. ; 
but of the greatest importance is the discovery of a form closely allied to 
Axima Walker, and that convinces me that this genus, separated by recent 
writers as the type of a sub-family, Aximtnce, is in reality nothing but*an 
abnormally developed form belonging to this group. 
This new form has the thorax, abdomen, and wings of a Eurytoma, a 
head similar to Axima, only the frontal spines are not so prominent and 
less acute ; the head is deeply emarginated for the reception of the anten- 
nal scape, with sharp ridges or carinae between it and the eyes. 
In this group I believe should also be placed the genus Chryseida Spin- 
ola, although Prof. Westwood has placed it with the Perilampince. 
The next sub-family, or the Ckalcidin&i is most abundant, South 
America apparently being the home of this group. Such genera as Dir- 
rhinus, Thaumatelia, Spilochalcis, Smicra, Chalets, Haltichella, Poda- 
grion, &c., have been recognized. 
Dirrhinus has not before been reported from South America, the known 
species being from the south of Europe and Asia. Its discovery on the 
Amazon is therefore interesting. 
One of the species of Podagrion, a genus parasitic in the eggs of Man- 
tis, is remarkable for its abnormally swollen antennal club. 
The Leucospince are poorly represented, but three species being in the 
collection. One of these, however, is Leucospis tomentosa Kirby, a rare 
species up to the present time, but a single specimen being known, Mr. 
Kirby's type in the British Museum. 
I consider the Leucospince closely allied to the Torymince, through cer- 
tain exotic genera, and through the Torymince we reach the Eupelmince. 
Eupelmince in South America spread out into many wonderful and re- 
markable genera, showing strong affinities with different groups, most 
perplexing to the systematist, and suggesting a closer affinity between 
this group and certain Pteromalids, such as the Cleonymides, Chiropach- 
ides, Miscogastrides, &c. Their tout ensemble is the same, and un- 
doubtedly a close relationship exists between these groups, difficult to 
define at present, but when the forms of different countries are more abun- 
dantly collected and carefully studied a much more satisfactory and natural 
arrangement of these groups than that now in vogue can be devised. 
In the Eupelmince, besides the genera defined in Mr. Cresson's " Syn- 
opsis," I would place Pelecinella Westw., Prionopelma Westw., Oodera 
Westw., Metapelma Westw., Epistenia Westw., Cleptimorpha Walker, 
Thautnasura Westw., and Solenura Westw. 
Phlebopenes Perty I do not know; but it probably belongs in this group. 
Westwood says Pelecinella is allied to Callimome, a Torymid genus;
