SOME GENERA OF F0RM1CWAL 889 



(Smith) must represent the g of jJEuictys, JEnictm and Typhlatta 

 inhabit tropical Asia, and have affinities analogous to those between 

 Labidus and Eciton. 



Emery ( Bulletin de la Soc. entom. ital, 1887 ) advanced this 

 hypothesis, which for that matter was self-evident once the S of 

 Dorylus and Labidus were known. 



Mr. R. C. "Wroughton, Divisional Forest Officer, Poona, having 

 sent me last year Mibictm airibigum (Shuck.) and a new JEn'u-tas, I 

 called his attention to the interesting problem of the £ of /En id us. 



I have just received from Mr. Wroughton a third species of 

 JEnictus, in company with a new species of Typhlatta, taken together. 

 The problem is therefore solved, and the honour belongs to 

 Mr. Wroughton, who writes laconically and prudently;; — "There are 

 some, what seem to me to be, JEnictus, n. sp., taken by Mr. Gleadow in 

 Thana. Had I been there I might have settled the question of 

 the ? and $ , but I have failed to find a nest so far." 



The result of this important discovery is that the genus Typhlatta, 

 Smith, (18-38, Proc. Linn. Soc. Zool. II.) must be dropped as 

 a synonym of the genus JEnictas, Shuckard {Ann. and Mag. Nat. 

 Hid., vol. V., 1840, p. 266 ). 



The capture of the JEntctits Wroughton'd, with its $ was made on 

 31st March, 1890. This date is most important as giving the time 

 of the year at which there is a likelihood of rinding the winged $ in 

 the nest. As in the genus Eciton the $ has one knot and the £ 

 two knots in the pedicle (i.e. of the abdomen). 



Genus JBNICTITS, Shuehml (Ann and Mag. Nat. Hid.) 

 ■ = TYPHLATTA, Smith (Proc. Linn. Soc, Zoo/., 1808). 



jEnictus Wrougldonii, n. sp. 



£ Length 2 "5 mm. Narrow and rather elongate. Head narrow, 

 elongate, the sides rather convex, and the posterior edge short and 

 rather rounded as in JE> Icmceps] but the head is much narrower and 

 longer than in that species. Anterior edge of epistome crenelate or 

 denticulate, not entirely hidden by the frontal ridges. No distinct 

 frontal groove. Terminal edge of mandibles rather long, micros- 

 copically denticulate, with one stout tooth at ihe extremity.
