Hijdrotcea ajaneiventris^ Macqnart. 



The female of this species closely reseinbles an Ophijra, 

 the frontal triangle beiii^ very lar^e and glossy, extending 

 almost to anterior margin and having the cruciate bristles 

 situated in its lateral margins ; the orbits and upper part of 

 ])arafacials are also glossy black. The entire body is glossy 

 blue-black in the female. The armature of the legs is 

 similar to that of last species, but the wings are clear, 

 sliglitly darker at bases, and the calyptnie are brownish uith 

 darker ma?'gins. 



One female, same locality as last species. 



On the strength of this female 1 should not hesitate to 

 place the species in Ophijra, but have not seen the male, and 

 as Stein has examined this sex and retains it in Hydrotcea I 

 cannot do otherwise than follow him, though I doubt the 

 propriety of the course. It may be distinguished from the 

 females of Oplnjra listed on a preceding page, which have 

 black palpi, by its having the hind tibia bristled as in 

 amescens. 



Hydrotaa villosa, Stein. 



A black species with similar habitus to that of dentijjes, F., 

 but the parafacials are broader and densel}^, almost golden- 

 ])ollinose, the line of demarcation between this part and the 

 glossy black part being very sharply drawn above ; the pyes 

 aie hairy ; and the male has the hind femur with several 

 series of long fine setnlose hairs below, the preapical ventral 

 bristles being liardly stronger than the others. The hind 

 tibia of male is normal, and has a long postero-dorsal bristle, 

 a series of setulose hairs along the antero-dorsal surface, 

 amongst which are some that are much stronger, and the 

 antero-ventral and postero-ventral surfaces with some fine 

 hairs. 



Originally described from Bogota, Colombia. One male 

 and two females from the same region as last two species. 



Hydrotaa houghi, Malloch.

Helina australasia, sp. n. 



Male. — Similar in colour to rcf/iucc, ^lalloch, but the 

 thorax is blackish blue instead of black, the abdomen is
