must be called '^' Polyrhackis affinis, Smith (nee Le Guillou) = P. vicina, 

 Roger." 



Smith (Proceed. Lin. Soc, March 1863) has described two different 

 species of Polyrhachis, P. dolomedes (No. 1, p. 14) $ and ? from 

 Ceram and P. dolomedes (No. 2, p. 16) $ from Waigiou, under the 

 same name ! Analogous mistakes have been committed several times 

 by Smith : for instance, in Journal Proceed. Lin. Soc. Suppl. Vol. V, 

 pp. 104, 105, two quite different Ponera simillima, Smith, are to be seen : 

 the one p. 104 = Lobopelta diminuta, Smith, and the other p. 105 r= 

 Ponera affinis, Roger (sec. Mayr, Verb. k. k. zool.-bot. Ges. Wien, 1862, 

 and Roger Berl. ent. Zeitschr 1860). But the double Polyrhachis dolo- 

 medes is not yet corrected, and I propose to name the P. dolomedes 

 No. 2, Polyrhachis pseuadonyma, n. sp., if this species is not synony- 

 mous with P. xiphiaSy Smith (1. c.) !

16. M. viATicus, Fab. (Mant. Insect, sist. 1787), $ . Kiirhurbali. 

 This Mediterranean species has hitherto been found to extend only as 

 far as Persia and Turkestan, and is here recorded from India for the first 

 time. The Indian specimens are typical, only a little more pubescent on 

 the metanotum.

17. D. MOGGRiDGEi, n. sp., ?• Length 2. 3 millims. Head short oval, 

 broad, with very convex sides, very straitened behind, and there also 

 semicircularly emarginate, about the neck of the pronotum. The pos- 

 terior edge of the head, about the slope, is sharp, slightly raised, and 

 nearly angle-shaped at both ends. Clypeus anteriorly with a deep, 

 transverse, and curved impressed line, which runs from one anterior angle 

 of the head to the other. The clypeus is very convex behind this im- 

 pressed line. Frontal area and frontal sulcus indistinct. 



Viewed from the side, the thorax ascends straight from the neck 

 towards the middle of the mesonotum, this middle being the summit of an
