Genus Christya. 89 



extending to the anterior branch of the second vein ; a few other spots on 

 wing field. 



Length. — 5 * 5 mm. (body) ; 2 * 2 (palpi) ; 4 * 5 wings. 



Habitat. — Wuri on the Carneroons." 



Note. — Said by Dr. Zieman to be undoubtedly concerned 

 in transmitting malaria. 



This is probably nothing more than 31. mauritianus, Grandpre.

I have not seen this insect amongst those sent by Dr. Ventrillon 

 from Madagascar. It resembles M. mauritianus, but is said by 

 Laveran to have unbanded palpi. 



Probably it will prove to be merely that species, which occurs 

 in Madagascar. 



Laveran also records it from Reunion.

Head clothed with long upright forked scales and some short 

 scales rather broadened in front ; palpi densely scaled ; thorax 

 with hair-like curved scales and narrow-curved lateral ones; 

 prothoracic lobes with narrow-curved scales ; abdomen with hairs 

 and dense lateral tufts of long hair-like scales, the tufts apical and 

 also other long lateral hairs ; wings with dense short lanceolate 

 lateral vein-scales ; fork-cells rather short. The 9 only known. 



A marked genus but closely allied to Myzorhynchis, from 

 which it is easily separated, however, by the long lateral tufts of 

 abdominal hair-like scales. 



It was first found by Dr. Christy, who noticed its peculiarities 

 and after whom the genus is named.
