to end of sixth segment of abdomen ; expanse of wings 125 mm. ; 

 length of hind-wing 51 mm. ; length of posterior legs 40 mm. ; 

 length of posterior femora 19 mm. ; of posterior tibise 13 mm. 

 The tarsal claws have a basal internal dilatation followed by one 

 sharp tooth. 19 ante-cubital and 9 post-cnbital nei'vules in the 

 anterior wings (For detailed description of $ , cf. Hagen, Yer- 

 handl. zool.-bot. Gresells. Wien, 1867, p. 35). JEscJina 2^enta- 

 cantha, Eambui", ^, agrees entirely with Eambur's (?) and 

 Hagen's ( c? ? ) description, but there are only 15 post-cubital 

 nervules in the anterior wings (17 in posterior) instead of 19. I 

 have not seen the ? , but the eyes in the ^ seem to be connected 

 in a longer space than is described by Rambur for the other sex. 

 An extremely rare species. 



CoEDULiiNA. Macromia transversa, Say, (^ , and CorduUa cynosura, 

 Say, $ ; neither of them an abundant species. 



Lii3ELLiTLi:>fA. The best are probably Lihellwla semifasciata, Burm., 

 and L. jjJumhea, Uhler ; but, as in the other tribes, most of the 

 species belong to the Southern rather than to the Northern States. 



The other groups of Neuroj^tei^a are scarcely represented ; but 

 there is a (^ of Pfynx ap2}e]idiculatus, F., a species beautifirily figured 

 by Abbot in his collection of drawings now in the British Museum. 



The few insects from Leske's collection seen by me are prepared 

 in a peculiar manner, each being stuck on to a piece of cork, and this 

 gummed into a little glass case (one insect in each), bearing a number 

 corresponding to that in the ' Museum Leskeanum.' The only type 

 is Semhlis ecaudata, Zschach, No. 236, 'exotica': tliis is a small Mnn- 

 tisjya without head and prothorax, utterly indeterminable specifically.

J^ote on Pidex obtusiceps, Ritsema, = P. taJjJce, Ciuiis. — Seeing my note on 

 Pulex taljjcB in the Nat. Hist. Trans, of Nortliuinberland and Durham, iii, p. 378, 

 Mr. C. Eitscma, Conservator at the Eoyal Museum of Natural History of Leyden, 

 wrote to me for examples of it ; these I had mueh pleasure in sending to him. In 

 liis reply he informed me that the two ((J & $ ) sent by me were the same as his 

 Pulex obtusiceps, described and figured in the Tijdschr. Ent. (2nd scries) iii, 1868, 

 and in his opinion not Pulex talpcB. I therefore sent my specimens up to the British 

 Museum, where they were carefully compared with Curtis's type of talpcB by ISIr. 

 C O. Waterhouse, who found them to agree in every essential character with it. 

 The specific name proposed by the learned Dutchman must therefore become a 

 synonym. ^Thos. Jno. Bold, Long Benton, Ncwcastle-on-Tyue : Jan. 31s/, 1874.
