150 Psyche [August 
brown band, and with traces of yellowish-brown dorsad at base of the 
second abdominal segment; the legs, excepting the concolorous black cox, 
and the scape fuscous, the femora dorsad and laterad variable, usually 
with blackish, especially in the caudal and cephalic femora; scape darker 
dorsad, pedicel and ring-joints with some yellowish; exposed portions of 
the mandibles black or dark fuscous; palpi dusky; tegule black; tarsi 
slightly paler, their distal joint black; wings subhyaline, the marginal 
vein conspicuous, black, especially proximad, the remaining venation dusky 
with some yellowish. Eyes dark garnet, with several discal black spots; 
ocelli pinkish, inconspicuous. Ventum concolorous, except as noted in the 
abdomen. 
Pubescence of body moderately close, inconspicuous. Abdomen polished. 
Flagellum moderately densely pubescent, the hairs short and closely 
applied; scape cylindrical, narrowing somewhat distad, equal in length, 
nearly, to the pedicel, ring-joint and 3 proximal funicle joints combined; 
pedicel long-obconic, its proximal end slightly curved, nearly thrice wider 
at its apex than at its base, not quite a third of the length of the scape and 
at least a fourth longer than the first funicle joint and its apex wider 
than that joint; ring-joint transverse, not as wide as the pedicel and about 
a fifth the length of the first funicle joint; first and second funicle joints 
subequal in length, both widening somewhat distad, the second somewhat 
wider than the first, each nearly a third longer than any of the next five 
funicle joints which are subequal in length, each, however, very slightly 
shorter than the one immediately preceding; the proximal club joint sub- 
equal in length and width to the seventh or distal funicle joint, the inter- 
mediate joint small, the apical joint small, obtusely conical, half the size 
of the preceding. Funicle joints 2-7 subquadrate. Club as a whole ovate, 
not much, if any, wider than the funicle, not equal to the united lengths of 
the three distal funicle joints (joints 5, 6 and 7 of funicle). 
(From 194 specimens.) 
Male. Length variable; 1.3-2.2 mm.; average, 1.82 mm. 
The same as the female, differing in the usual secondary sexual characters 
pointed out in the generic description, and in color as follows: The base 
of the abdomen in the dorsal aspect has a large conspicuous, rounded, 
honey-yellow spot, distinct to the naked eye, which is but slightly indicated 
in the female by the presence of some yellowish-brown in that region; in 
the same region ventrad, the area is larger than that in the female and 
rounded. The antenne have an additional ring-joint, one joint less in the 
funicle and a very minute, additional fourth club joint, which are the un- 
usual secondary structural features. 
Flagellum filiform, pilose. Scape slender, a fourth longer than the 
pedicel, ring-joints and first funicle joint united; pedicel obconic, not as 
long as in the female, not by far a half the length of the proximal funicle 
joint, subequal in length to the distal (6th) funicle joint; ring-joints 
transverse, the second nearly twice the size of the first and darker in color; 
funicle joints all longer than wide, abruptly shortening distad; first funicle
