262 Mr. Shuckard's Monograph of the Dorylidae, 



Media. Antenna- nigra : nrticulo secundo basi ferrngineo. Caput nigrum, 

 labio cinereo villoso. Thorax niger, arcu antico cinereo. Abdomen 

 rufum, pctiolo anoquc nigris. AUc obscurse. 

 Latreille and St. Fargeau have surmised, from the country of this 

 insect, and from FabricillS having associated it with his Doryli, that 

 it mibt be a Labidus* I think, however, both from the distribution 

 of colour and his description of the labium (labrum), that it cannot 

 belong: to either of these genera ; but what it may possibly be I can- 

 not at all surmise. 



\.B. Dr. Maximilian Perty, in the 'Delectus Animalium Arti- 

 culatorum' of the Brazilian Travels of Spix and Martius, has figured 

 in plate 27, fig. 11, a Labidus which he calls Lab. Latreillii, and at 

 p. 13S he thus describes it : — 



Tot us badio-testaceus, albido-pubescens ; ocellis magnis, hyalinis ; 

 alls albis, ?iervis flavicantibus. 



Length 7 lines, width of prothor. \\ line. 

 Expansion of the wings 16 lines. 

 He says it occurs in the province of Piauhiensi and in Southern 

 Brazil. 



It is very probable that this is a distinct species, or that the species 

 from each of these localities are different, but without a careful ex- 

 amination it is impossible to say. If however they are both of the 

 same size, and the expansion of the wings is the same, they are 

 doubtlessly identical ; the proportions between the expansion and 

 the length differ so considerably from any that I have described, and 

 as by a comparison with the description of the genuine Lab. La- 

 treillii above it appears evidently different from that, I therefore 

 propose to call it 



? Sp. 11. Lab. Pertii, Shuck. 



Lab. Latreillii. Perty, Del. An. Art. Tab. 27- fig. 11. p. 138. 



Genus Typhlopone, Westw.* 



Head oblong, convex, emarginate behind, occasionally longitudinally sul- 

 cated, and nearly as long as the thorax, not exhibiting either eyes 

 or ocelli. 



Antennce about as long as the head, inserted within two short parallel 

 facial carinae, and close to the anterior margin of the clypeus, geni- 

 culated and subclavate, consisting apparently of only ten joints; the 



* Mr. Westwood has neither given a generic nor specific description of 

 what he calls Typhlopone fulva ; he has only given an outline of the insect, 

 and of its maxilla and labium and their palpi, and described the mandibles. 

 See Introd. to Mod. Class, of Ins. vol. ii. p. 226. fig. 86, and the descrip- 

 tions at p. 219. And he has not noticed the remarkable structure of the 

 antennae, apparently wanting two joints.
