"Nov. 24, 1899. Dear Mr. Harvey: — As Ophiogomphids 

 go I should consider anomalus distinct from niainensis. The 

 occipital spines differ slightly, but the series is insufficient to 

 decide the value of these differences. The abdominal markings 

 and the appendages are, however, quite distinct. Mainensis is 

 a more robust species than a7t077ialus, and excepting the lateral 

 spot is without markings on the last three abdominal segments. 

 The appendages are fulvous in mainensis. Yours truly, 



"Samuel Henshaw." 



Prof. Needham has also pointed out the great resemblance 

 between carolus Needh. and niainensis. Without attempting 

 to make any positive statements with regard to these three 

 species, they appear to be distinguishable, as far as present 

 information goes, by the following features : 



Anomalus. Total length $ 39-44, 9 39-41- Inferior ap- 

 pendage of % greatly upcurved in apical half. 9 occiput with 

 the spines contiguous, 8-10 abd. segs. with dorsal yellow spots. 



Mainensis. Total length 9 46 mm. (S unknown). 9 oc- 

 ciput with the spines contiguous, 8-10 with no dorsal yellow 

 spots. 



Carohis. Total length 40-42 mm. Inferior appendage % not 

 upcurved in apical half. 9 occiput with spines not contiguous, 

 8-10 with dorsal yellow spots. 



The shapes of the vulvar laminae also differ, according to 

 Prof. Needham's figures (Can. Ent. xxxi, p. 237). 



It remains to be seen whether these differences are constant.

We were fortunate in taking seven specimens of this rare 

 species (six males and one female) on Russell stream near N. 

 E. Carry, Me., August 25-27, 1899. So far as we know, the 

 types are the only specimens that have been taken. The 

 capture is important also, as establishing a definite locality, as 

 the exact locality of the types was not known. (See Psyche, 

 March, 1895, p. 210.) The species was flying over swift water
