the allied forms. The middle and lower discocellulars of the primaries are more nearly 

 at right angles to the axis of the wing than in the other genera of this subfamily, the 

 first, second, and third subcostal branches lie close together, the second and third 

 submedian segments are subequal ; the cell of the secondaries is very long, the median 

 side being much longer than the costal side, the discocellular is convex towards the 

 base, and meets the median at the origin of its second branch. The hind tibiae have a 

 dorsal ridge of hairs. On the upper surface the male has a small tuft of hairs near 

 the base of the submedian nervure of the secondaries. 



1. Oxynetra hopfferi. (Tab. LXXIV. fig. 18 e .) 



Oxynetra hopfferi, Stand. Exot. Tagf. p. 294, t. 99 \ 



Alis chalybeo-nigro ; anticis fascia mediana lata semihyalina venis quadripartita a vena subcostal! per cellulam 

 usque ad venaru submedianam extensa, posticis macula mediana bifida punctisque binis ultra earn semi- 

 hyalinis : subtus ut supra, posticis saturatioribus maculisque duabus bene separatis, infra venam medianam 

 glaucescentibus ; capite nigro albo punctato, tegulis ad basin macula rufa notatis, abdomine rufo cincto, 

 palpis et pectore albis, abdomine subtus albo punctato.

Dr. Staudinger has kindly lent us his unique type of this very distinct species, which, 

 though evidently a typical Oxynetra, differs in many respects both from 0. semihyalina 

 and O.felderi. The large hyaline spot of the primaries, except for the nervures, is 

 entire, and there is no subtriangular spot beyond it in the direction of the apex, a 

 feature possessed by both the other species. The abdomen above is also distinctly 

 banded with rufous, which is not the case in either 0. felderi or 0. semihyalina. 



The genitalia of the male of 0. felderi differ in many respects from those of any 

 other member of this subfamily which we have examined. The tegumen is very short 

 and terminates in two claw-like hooks, and there are no lateral lobes or spines ; the 

 scaphium is distinctly chitinized. The harpagones are complicated structures, having 

 a strong terminal upturned, but not recurved, hook, from its dorsal edge a curved rod 

 runs backwards and is suddenly bent into a hook ; this inner hook falls within the disc 

 of the each harpago. (See Tab. LXXIV. fig. 19.)

Dis annulatus, Mab. Bull. Soc. Ent. Er. ser. 6, ix. p. clxxxiv (1889) l . 



Alis nigricanti-fuscis unicoloribus, posticis ciliis ad angulum analem albo intermixtis : subtus ut supra, posticis 

 viridi tinctis ; corpore cbalybeo-cyaneo, abdomine segmentis duobus proxiinis rufo notatis ; capite nitide 

 cyaneo albo punctato, punctis duabus ad basin antennarum, una inter eas et duabus post oculos ; palpis, 

 pectore et maculis abdominalibus albis.

Dr. Staudinger has kindly lent us the type of this interesting species, the only one 

 that has been hitherto obtained ; it is apparently a female, and, having regard to this
