Psyche 
[February 
punctured above, more coarsely and sparsely so below; propo- 
deum very finely and closely punctured laterally, more sparsely 
so posteriorly; tegulse piceous, finely punctured, the punctures 
widely separated; wings pale fuliginous, more strongly so apically 
and along costa, nervures testaceous, basal nervure much beyond 
transverse median, second recurrent nervure entering second 
submarginal cell slightly nearer apex than the first does to the 
base; legs black, black pubescent, that on the tarsi beneath and 
on the mid tarsi without, with somewhat of a fuscous tinge; 
middle metatarsi almost as broad as their tibiae and the hind 
metatarsi fully so; spurs reddish-testaceous; claws testaceous 
basally, ferruginous apically, with short but distinct basal teeth. 
Abdomen cordate, shining, segments with but few scattered 
punctures apically, but more numerous on basal portions of 
discs, bare of pubescence above, the concavity of the first segment 
peculiar in having a longitudinal sharp ridge dividing it into two 
separate concavities; segment 6 but very slightly concave at 
sides viewed from above, practically straight in profile, the sur- 
face hidden by fine appressed brownish pubescence, which 
contrasts rather strongly with the otherwise black abdomen; 
scopa entirely black; apical ventral segment with a free polished 
apical lip which projects slightly beyond the scopa. Length 11 
mm. 
Type: Female (Type No. 15716, Mus. Comp. Zook); Man- 
grove Cay, Andros, Bahamas, Aug. 1, 1904 (Allen, Barbour and 
Bryant, collectors). 
This is close to M. maura Cress, but differs in the color of the 
pubescence, in the double punctation of the vertex, and in the 
peculiar ridged condition of the concavity of the first abdominal 
segment. In maura the pubescence is deep black, the vertex has 
only a few scattered punctures and no evidence of double punc- 
tation and the basal concavity is normal.
