than five of them, Ichneumon, Pimpla, Anomalon, Dryimis, and Os- 

 mia, being represented by new species. Of the latter genus a second 

 •new species is indicated ; and of Dn/inus no fewer than five others are 

 described. 



But the most interesting plate of the volume is that which illustrates 

 the Strepsjptcra by figures and dissections of a new species of Stylops, 

 named, in honour of its discoverer, Stylops Dalli. 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. " Antenna; 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. Lahrum and 

 " Mandibles wanting ? Pharynx visible. Maxilla arising betvi^een the 

 " eyes, very remote at their base, conniving, long, slender, lanceolate, 

 " and horny. Palpi arising close to the maxillcB, 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. Prothorax and Mesothorax very 

 " short lings, not so broad as the head. Metathorax very large and 

 " long, divided diagonally into four portions, and dilated very much on 

 " each side, producing a large Scutellum 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 mesothorax, 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
