This species has hitherto been recorded only from western Africa, but no doubt can, 

 I think, be entertained that the following specimens entirely coincide with the above 

 descriptions, which I am sure are those of the sexes of a single species. 



Five specimens were obtained of this insect on Mahe ; first in the cultivated country 

 at the end of 1908, and early in 1909 both at the Cascade Estate, and in the high forest 

 behind Trois Frei-es, all at an altitude of about a thousand feet. To the present species 

 also belongs the female recorded by Cameron (Trans. Linn. Soc. ser. 2, Zool., xii. 1907, 

 p. 79) from Trou aux Cerfs in Mauritius, where it was captured on 18th August, 1905, 

 under the tentative name of Ophion rufus, Brulle, which no one is now able to identify, 

 though it is certainly distinct from both O. rufus, Tosq. { = antarkarus Sauss., Grandid. 

 Hist. Madagasc.) and 0. rufus, Kriechb. 



9. Henicospilus antarkarus, Saussure.

Certainly the commonest African species of the genus ; I have examined examples 

 from Natal, the Kentani district, Madagascar, Mauritius, etc. In the present collection 

 is a single female found on Assumption Island in 1909 by R. P. Dupont. 



10. Henicospilus leionotus, Tosquinet. 



Ophion (Enicosjnlus) leionotus Tosq., Ichn. d'Afrique, 1896, p. 393, ?. 



I have examined a single female, which agrees to a remarkable extent with 

 Tosquinet's description, though several divergent points are so striking that I hesitate to 

 entirely regard it as synonymous therewith : principally the radial nervure is sinuate 

 almost as strongly as in Szepligeti's subgenus Dicamptus of Allocamptus Tlioms., the 

 antennae are nigrescent and much longer than the body, and the corneous discuidal mark 

 is dull ferrugineous. I propose to term it var. longicornis, var. nov. 



The example in question was captured on the marshy plateau of Mare aux Cochons, 

 on Silhouette, at an altitude of over a thousand feet on 27th August, 1908. 



Xanthocharops, n. n. 



Having the capital, pedal and thoracic structure of Charops, Holmgr. (Sv. Ak. 

 Handl. 1858, p. 39), though materially differing in its subclavate and pale-banded 

 flagellum, subdeplanate and shorter abdomen, and in the alar venation : — radial nervure 

 basally curved, emitted from basal third of the somewhat conspicuous stigma ; external
