interruptions at the longitudinal junctions. Hind tarsi white 

 tipped, and broadly apically white banded on all joints ; the first 

 having an additional apical and middle band. Thorax with marked 

 adornment. 



$ . — This is the smallest species I have handled, being barely 4 nnii. 

 long, and the wing less than 3 mm. The thorax is strikingly adorned, 

 in a way very unusual in the genus, by means of white scaled lines on 

 the fuscous ground colour ; of these there is a pair of sub-median and of 

 lateral lonj:;itudinal lines and an external lateral pair curved nmch as are 

 those of Steg. fasciata. The proboscis and palps are of equal length and 

 entirely black, save for a few white scales on the tips of the joints of the 

 latter. The eyes have a minute white border and there is a distinct 

 white, bifid frontal tuft. Besides the dorsal thoracic adornment, there 

 are wliite tufts on the pleural and coxae. The tibia) have a sub-apical 

 whitish patch. The anterior tarsal joints are broadly apically white 

 banded, saving the last, and the first has in addition two black, 

 alternated with two other white lengths, maldng five in all. The mid 

 tarsi are dusky throughout, the banding of the joints being obscure or 

 absent. The abdomen is hirsute and fuscous throiighout, with the hind 

 borders of the segments somewhat paler. 



Habitat. — Received from Dr. Lutz, who writes that it is the wood 

 Anopheles of Brazil, breeding in ponds, the adults frequenting woods 

 in mountainous regions, serving as the transmitter of malaria in places 

 where there are no swamps.
