than five of them, Ichnewmon, Pimpla, Anomalon, Dryinus, and Os- 
mia, being represented by new species. Of the latter genus a second 
new species is indicated; and of Dryinus no fewer than five others are 
described. 
But the most interesting plate of the volume is that which illustrates 
the Strepsiptera by figures and dissections of a new species of Stylops, 
named, in honour of its discoverer, Stylops Dalii. Opportunities of 
examining insects of this order are so extremely rare, that entomologists 
are still at a loss with respect to many points, even of their external 
structure. Some of these have received considerable elucidation on the 
present occasion, and we are therefore induced to extract entire Mr. 
Curtis’s description of Stylops, the only genus of the order that has yet 
occurred in this country. ‘‘ Antenne inserted between the eyes, near the 
** crown of the head, membranous, perforated or punctured, composed 
of six joints, the basal one somewhat cup-shaped ; second very short, 
“* transverse ; third produced on the internal side into a dilated hollow 
*« lobe, extending beyond the fifth joint ; fourth large, subclavate ; fifth 
“« smaller, subovate ; sixth as long, ovate, compressed. Labrum and 
** Mandibles wanting ? Pharynz visible. Mazille arising between the 
* eyes, very remote at their base, conniving, long, slender, lanceolate, 
** andhorny. Palpi arising close to the maville, large and robust, 
** membranous, indistinctly pubescent, biarticulate, basal joint subconi- 
** form ; second attached to the oblique apex of the first, oblong, some- 
“« what truncated obliquely. Mentum very obscure. Labium and 
** Palpi none. Head sessile, very broad and short, producing a large 
** triangular lobe in the centre. Eyes very remote, lateral, globose, 
** composed of numerous hexagons. Prothorar and Mesothorax very 
* short rings, not so broad as the head. .Wetathorax very large and 
** long, divided diagonally into four portions, and dilated yery much on 
** each side, producing a large Seutellum projecting over the Abdomen, 
* which is small, soft, and composed of eight or nine joints, terminated 
* by an incurved Oviduct ? Anterior wings short and narrow, attached 
* to the sides of the mesothorazx, subcoriaceous, pubescent, thickened at 
*« the costa and inflated at the apex. Posterior wings attached to the 
* metathorax, folded longitudinally when at rest, and meeting over the 
** body, very large and membranous, the costa thickened, the nervures
