tion, seemed likely to be recognised most easily. It is 

 quite possible that some of these characters are merely 

 " individual,' 1 but of this there is always a chance when 

 attempts are made to diagnose the characters of a species 

 from a single specimen. 



I will now give my Synopses of Genera and Species, and 

 these will be followed by a few detached Notes, or 

 " Excursuses," dealing with various questions which came 

 up for consideration as my work proceeded. These are 

 mere Tentamina, and probably very crude, for they often 

 touch on subjects with which my acquaintance is very 

 recent. But it has interested me to write them, and I hope 

 no harm will be done by publishing them in their present 

 shape . 



SYNOPSIS OF THE GENERA. 



(Genera marked thus f cannot be considered as indigenous.) 



1 . Antennae (see Figures in Plate XII, Figs. 1,2) inserted close to t lie 

 mandibles — lower down in the face than the lowest part of 

 the eyes.* On each side of the head above (very near each 

 eye) runs a series of little tubercles. Middle and hind tibiae 

 denticulate along their hind-margins (PI. XII, Fig. 18). The 

 § hypopygiuni appears as a sort of compressed longitudinal 

 carina (in the middle of the 5th ventral segment). In the lateral 

 view it is tooth-like (subtriangular) ; and beyond it is seen 

 the exposed part of the paradoxically long and slender 

 " terebra " or boring-organ (a modified ovipositor), resembling 

 merely a fine hair, unless really highly magnified, when the 

 apices of its paired "spicula" are seen to be armed with a 

 very few minute teeth. (Its structure and attachments are 

 very like those of the corresponding organ in a Cynipid /) 

 Cf. Figs. 1, 2, 3 in PI. XIII. In the J the apex of the abdomen 

 is simply convex above and below. The labial palpi are 

 short, .'!- jointed; the maxillary palpi much longer, 5-jointed. 

 Each fore-leg lias one calcar only; each posterior leg 

 has two, but one of them is so short that it may easily be 

 overlooked. Neuration of wings very incomplete. The 

 antennae have 12 joints in the $,11 in the <$. 



( Family Oryssidae.) Genus 1. Ophrynopus, Konow. 



* Hartig and others say " below the clypeus," but what they 

 take lor the clypeus is in this case realty a part of the abnormally 

 developed " frons." The true clypeus is to be found lower down, 

 between the insertions of the antennae and the mouth-parts, as in 

 all Hvinenoptera (I believe) without exception !
