slenderer than in Achias; in the female the head iias the ordi- 

 nary shape. Laglaisia bears a striking generic resemblance to 

 Addas ichneumoneus Westw. Trans. Ent. Soc. Lond. V, p. 235, 

 Tab. 23, f. 8 (the species are evidently distinct, as Z. caloptera 

 has banded wings); nevertheless there are differences which 

 still leave me doubtful whether A. ichneumoneus is a Laglaisia. 

 The anal cell of Laglaisia is closed by a crossvein which is 

 convex (for instance as in Loew, Mon. N. Am. Dipt. Ill, Tab. 8, 

 f. 2) and not concave, as in M.*" Westwood's figure of A. ichneu- 

 moneus. The structure of the head, as seen in front (Westw. 

 1. c. f. 8a) is somewhat different. There is, at the end of the 

 abdomen (</) a tuft of a few long hairs, which do not exist 

 in A. ichneumoneus </■. Finally, the female of the latter spe- 

 cies, as described and figured, is provided with oculiferous pe- 

 duncles, although they are shorter than those of the male. (It 

 remains to be proved however whether this is a female, as the 

 ovipositor is not mentioned in the description ; it may be a male 

 with shorter peduncles?). In Laglaisia, the tuft of long hairs 

 at the end of the abdomen (c/') and the shape of the anal cell 

 remind one of Cleitamia^ and it is probable that these genera 

 are related, the more so as the patria is the same.

 has the ocuhferous peduncles even longer than Laglaisia :, and, 

 nevertheless, in the system, it is far removed from Achias j, or 

 Laglaisia. It is a true Micropezid , related to Calohala and still 

 nearer to my new^ genus Nestima (New Guinea). It has the 

 body, the wings, the legs and the male anal appendages of 

 the Micropezidae ; even the white front tarsi! 



Scutel and metathorax have the same gibbous structure as 

 in Nestima. I could not verify the structure of the middle fe- 

 mora, because they were broken in the two specimens which 

 I saw ; nor of the ovipositor , because the specimens were males. 



A. Lorquini is identical with Phytalmia guttipennis Walker, 

 J. Proc. Lin. Soc. V, 269, 1861 (Waigiou). As it is not a Phy-
