2P>6 Mr. Shuckard'a Monograph of the \)i)Y\\\<\w, 



is dedicated to John Curtis, Esq., the author of the British Ento- 

 mology, in which work the portions devoted to the Hymenoptera 

 were evidently a labour of love. 



Sp. H. Lab. (3. Typhlopone) Westwoodii, Shuck. Length 3 lines. 



Tettaceui ; capite (mandUntlu piceis execptis) castanco nitido, valdc pu?ic- 



(at<> el in medio tulcato. 



Pale reddish testaceous. Head bright chestnut, shining, rather closely and 

 deeply punctured, deeply sulcated longitudinally above in the centre, 

 the channel dividing the head into two halves; mandibles pitchy red. 



Thorax more closely and deeply punctured than the head, and about its 

 length. 



Abdomen brightly shining, scarcely punctured, the peduncle quadrate, 

 opake, convex, the ventral portion produced into an acute tubercle, 

 the following segments slightly constricted at their base, the apex of 

 the terminal one subreluse, armed on each side with a minute spine, 

 and its ventral portion also furnished with a minute central spine. 



In my own collection. 

 From South America. Its distinction from the two preceding 



consists, exclusive of size, in the entire longitudinal sulcation of the 



head. 



Genus ^nictus, Shuck. 



Body elongate cylindrical. 



Head small, transverse, flat. 



Antennae short, setaceous, curved, inserted upon the anterior margin of the 



clypeus, and not quite so long as the insertion of the superior wings, 



the scape about one-third the length of the flagellum, the joints of the 



latter equal. 

 Eyes globose, lateral, and very prominent. 



Ocelli placed in a slight curve upon the vertex, large and very prominent. 

 Mandibles edentate, elongate, slender, compressed, very much curved, 



slightly broader at the base, and forcipate. 

 Labrum truncated at the apex, where it is emarginate in the centre.

Maxillary palpi > ? * 

 Labial palpi 

 Thorax short, oval : collar or prothorax more developed than in Dorylus, 



and not concealed in front by the gibbosity of the mesothorax : scu- 



tellum quadrate, very gibbous, slightly projecting over the metathorax, 



which is perpendicular. 

 TegulcB small but distinct. 

 Superior wings with a large stigma, one acuminated, marginal cell angu- 



* The internal trophi I am obliged to pass over, but as they are scarcely 

 distinguishable in the large species ofJDorylus,'m a small insect like the pre- 

 sent, which is at least fifty times less, the investigation would incur a cer- 

 tainty of destruction without possibly effecting the object; but it is quite 

 sufficiently distinguished by its more obvious characters.
