"Following is the copy of a note which I made in June, 1899, 

 on Morse's type of Tetragoneuria indistincta in the M. C. Z. 



" 'Tetragoneuria indistincta Morse. An examination of his 

 type shows that his expression "basal part of median space and basal 

 antecubital cell of each series fuscous" refers only to the hind wings, 

 not to the front, on which there is merely a very small brown spot in 

 the subcostal space reaching- only % °^ the way to the first ante- 

 cubital. 



" 'A female from Peterborough, N. H., June, '88, agreeing in other 

 respects with indistincta has the right app. rounded at tip, the left 

 acute. 



" 'I suspect that indistincta = spinigera 



> )> 



This latter condition — female appendages of unequal length 

 — is one not infrequently found in Tetragoneurice. In placing 

 indistincta with spinigera I base it? identity upon the black 

 T-spot, the length of the appendages and the color description, all 

 of which agree perfectly with spinigera. 



Tetragoneuria canis MacLachlan. 



Colors brown, black yellow and olive. Similar to the preceding 

 species in the main points. 



T-spot never present. The pile on the thorax gray and very 

 little mixed with brown. The insect therefore presents a much lighter 

 appearance than spinigera. 



The color of the wings is confined to a few basal spots. In 

 general the wings throughout show a decidedly flavescent tinge, not 

 hyaline as spinigera. 



The male appendages with the apical third sharply bent down- 

 wards,, a tubercle at the bend. In lateral view beneath regularly 

 rounded, with several tubercles. 



The following material is before me :

Museum.
