Deam: 1 3). 
The examples from Florence were taken in June and July, those from Lower 
Calfornia in April, September, and October, those from Guadalajara and Uruapan 
in July. The Guadalajara male has a brown stripe on the partly obsolete first lateral 
thoracic carina, and the sides of abdominal segment 8 are yellow for their entire 
length ; the Uruapan individual has this latter feature. 
Although Selys and Hagen, in their latest paper 2, regarded odscurus and borealis as 
identical, I have ventured to separate them again, the differential character drawn 
from the carina of the male superior appendages being herewith presented for the 
first time. I doubt whether Hagen recognized the true borealis, especially since he 
labelled the above-listed material from Arizona in the M. C. Z. “meridionalis” 
(cf. Trans. Amer. Ent. Soc. xii. p. 276, 1885). 
4. Progomphus pygmeus. (Tab. VII. figg. 4, 4a.) 
Progomphus pygmeus, Selys, Bull. Acad. Belg. (2) xxxvi. p. 502 [58] (1873)’. 
3. Face pale green, tending to yellowish inferiorly and on the lips, an obscure dark mark on the middle of 
the anterior surface of the frons inferiorly ; vertex pale brown, occiput darker, its hind margin concave ; 
rear of head dark brown, with two pale green spots on each side. 
(Head wanting in the unique type.) 
Front wings with 12-13 antecubitals, pterostigma 2°5-3°5 mm., 14 double cells (right) or two rows for 2-3 cells 
(left) in the middle of the area between the second sector of the triangle and the hind margin (San 
Gerdnimo d) or one row throughout (Bonda ¢), two submedian cross-veins on the right side only 
(San Geronimo). 
Q (hitherto undescribed). Vertex, occiput, anterior surface of frons, nasus, and labrum brown, rhinarium and 
superior surface of frons green; hind margin of occiput almost straight, rear of head black, hind margin 
of each eye with a distinct rounded emargination at about the level of the upper surface of the frons. 
Pale green antehumeral stripes narrower than in the ¢, produced toward the median line at the lower end 
so as to approach the form of an inverted 7, no brown at the first lateral thoracic suture. 
Abdomen dark brown, sides of 1 and 2 pale green, 3 with a mid-dorsal linear yellow spot on the middle of 
the segment.
