17. Also Colorado 2562 (Fort Collins, June n, 1893, C. P. Gil¬ 
lette, collector), 1170 (Fort Collins, June 13, 1893, C. P. Gillette, 
collector) and 623 (Fort Collins, July 5, 1903, C. P. Gillette, col¬ 
lector). 
Nomada (Nknnadula) mariinella, Cockerell. 
Three 9s (sent by Prof. Gillette) are variable, and do not sup¬ 
port the idea that the Colorado form is distinct from that of New 
Mexico. Two are from Fort Collins, May 28 and June 19; the 
other is marked Colorado 2521 (Fort Collins, May 28, 1897, E. S. 
G. Titus, collector). 
The $ of N.martinella has not been described, but I find 
three specimens in the Colorado collection. They are closely allied 
to N. scita , but are readily separated by the broader abdomen and 
darker legs; the tegulse are bright lemon yellow with a hyaline 
spot; the thorax is covered with coarse hair which has a decided 
brownish tint. The scape is more swollen than in scita, and the 
yellow of the face is darker and stronger. The hind femora are 
stout with the lower edge decidedly concave. The scutellum is 
black. These 3s are marked Fort Collins, May 20 and 21, and 
Colorado 2521. 
Namada (Micro nomad a) vegana, (Cockerell). 
This was described as a variety of N. mod^sta, but it seems to 
be a distinct though closely allied species. The ^s are like true 
?nodcsta > but uniformly small. Prof. Gillette sends five ^s and 
two $s. They are mostly from Fort Collins, July 4 to 20; one is 
marked Colorado 1204 (Fort Collins, June 26, 1893, attracted to 
Heliantlius leaves by their secretions.—C. F. Baker, collector). 
Nsmada iMicronomatia) vogana variety niisscons, new variety. 
9 , just like vegana, except that the mesothorax, instead of being 
very closely punctured, has large irregularly scattered punctures on a 
shining ground. The ground-color of the first abdominal segment is red, 
and there is a red supraclvpeal mark. Perhaps a distinct species. 
Fort Collins, Colorado, August 8, 1899 (E. S. G. Titus, col¬ 
lector). 
Namada (Micranomada) Samarensis, new species. 
<3\ length about 91 mm.; red, yellow and black. Markings bright 
lemon yellow, the pattern as in N. vegana , except that the mark on the 
pleura is narrower, the marks on the metathorax are wholly absent, and 
the band on the second abdominal segment is extremely broad; the 
ground-color of the body is dark red, becoming black on the vertex, the 
anterior part of mesothorax,and the enclosure of metathorax,and almost 
black on the pleura below the yellow band; the fourth abdominal seg¬ 
ment is black anteriorly to the rather narrow yellow band, and the 
fourth ventral segment is black with two transverse reddish stripes, one 
on each side. The insect is much more robust than vegana (in build sim¬ 
ilar to wlieeleri ), and the head and thorax are very, coarsely punctured; 
the punctures of the mesothorax are extremely large, and many of them 
confluent. Those of the pleura also very large. Sides of vertex with the
