6r. Ophiogomphns anomalns Harvey. 



A second male was taken along the border of woods June 8, 



1898, and on June 7 and 8, 1899, 75 pairs were captured per- 

 mitting a more careful study of the male and a description of 

 the previously unknown female. 



The males vary in length from 39 mm. to 44 mm. The width of the 

 abdomen at the base of the 8th segment is fully 5 mm. in life instead of 

 2.5 as given in the original description. The spots on the dorsum of 9 

 and 10 are somewhat variable ; the most agree with the original descrip- 

 tion, but the spots on both 9 and 10 are sometimes obovate and the one 

 on 9 sometimes oblong. The superior appendages are armed with numer- 

 ous stout hairs. The hind wing is prominent at the anal angle as in the 

 male of O. carolus. 



9 (previously unknown). — Slightly shorter than the male, 39-41 mm., 

 but the hind wing slightly longer, 25-26 mm. Color, head and thoracic 

 markings and legs very nearly as in the male. Occiput armed with two 

 prominent spines which are close together, with the tips in contact. The 

 abdomen widening from the 7th to the 9th segments, loth narrower. 

 Mid-dorsal and lateral stripes as in the male, differing particularly in the 

 form of the spots on 9 and 10, which are more frequently semicircular, 

 curved side cephalad. The spot on 9 is sometimes square as in the male 

 and sometimes circular. The spot on 10 is sometimes nearly obsolete. 

 The marking on the side of 9 is not C-shaped as in the male. 



In both sexes there is a pit in the side of segments 8 and 9 ; the C-shaped 

 spot on the 9th segment of the male includes this pit ; the head and thorax 

 are very hairy ; the wings yellowish toward the base and the whole wings 

 give coppery reflections. 



[A comparison of five females, from Orono, June 7 and 9, 



1899, sent me by Prof. Harvey, with the figures of vulvar 

 laminae by Prof. Needham (Can, Ent. xxxi, p. 237) shows 

 that anomahis is most like that of carolinus Needham, fig. 35 ; 

 the differences are that the cleft and the interval separating 

 the two lobes are respectively somewhat deeper and wider 

 than in fig. 35.] 



This species will have to be added to those spoken of by 

 Prof. Needham as abundant, my son, Bartle Harvey, and 

 myself having taken with nets, in two days, about seventy- 

 five pairs. On the afternoon of June 7th I collected upon a 

 hill in a pasture, covered in part with clumps of small birches, 

 evergreens and low bushes. In one part the ground is springy, 

 overgrown with low bushes and grass. There is no running
