ginia. The flagellar joints are broader than long, and the pro- 
cess of the labrum is characteristic, being extremely broad, 
with a practically straight edge (not emarginate as in rud- 
beckiae), its color pale yellow, with the edge dark. 
Panurginus picitarsis n. n. 
Panurginus picipes Morawitz, Hor. Soc. Ent. Ross., xxiv (1890) 
p. 358—China. Not P. picipes (Cresson 1872). 
Panurginus labrosiformis distractus subsp. n. 
$ Length about 5 mm.; like P. rudbeckiae (Rob.), differing thus: 
smaller; b. n. barely falling short of t. m. (falling considerably short 
in rudbeckiae) ; the long and slender flagellum pale yellowish-red be- 
neath, except at base and apex; the broad-triangular process of labrum 
with a narrow truncate (not emarginate) apex, wholly different from 
the broad, emarginate process of rudbeckiae. As in P. rudbeckiae, the 
clypeus has a median groove. This agrees with P. labrosiformis Rob. 
in the narrowed process of labrum, and the impressed lines on the 
mesothorax; but the antenne are long and slender and the wings are 
quite strongly dusky. The supraclypeal spot is a mere point. The 
second and third abdominal segments have the depressed basal part 
dull, while the apical part is shining, with distinct minute punctures; 
in this the insect resembles P. asteris. Another similar species is P. 
bidentis (Ckll.); this has the process of labrum strongly emarginate. 
Hab.—Lincoln, Nebraska, August (L. Bruner, 9). Very 
likely a distinct species, but I describe it as a sub-species of 
labrosiformis (which I know only from description), as it 
seems to nearly agree in structure. In the table of Nebraska 
Panurginus in Ent. News, May, 1907, p. 184, it runs to 
P. renimaculatus, which has the process of labrum deeply 
emarginate. 
Exomalopsis zexmeniae sp. n. 
Exomalopsis pulchella Cockerell, Ann. Mag. Nat. Hist., July, 1912, 
p. 29 (not of Cresson). 
Very like E. pulchella Cresson, but the receipt of a series 
of genuine pulchella (from Liguanea Plain, Jamaica; C. T. 
Brues) shows that the Guatemalan species (type from Qui- 
rigua, at flowers of Zexmenia; W. P. Cockerell) is distinct 
by its rather larger size, black (instead of fulvous) hair of 
scutellum; more strongly punctured clypeus, but especially by 
the very large knee-plate of hind legs, that of pulchella being 
very small.
