but little stouter than the following ones, slightly longer than the 
third and fourth together, without crest of scales. Palpi long and 
slender; the second segment is a trifle shorter than the third, the

Locality: Guadeloupe, West Indies (A. Busck). 
1 9,16. Bred from larve found together in Bromelia water. 
The male is much denuded. Mr. Coquillet’s characterization of the 
male M. violaceus is based on this specimen. The palpi are re- 
markably slender in this species, a particularly noticeable feature in 
the female. Another unique feature is the absence of erect scales 
on the second antennal segment in both sexes.
