Dutch Guiana: Paramaribo, February 23, 1912, 49 S , 4. 9 ■ 

 Trinidad : Cumuto, March 8 and 10, 191 2, 4 5 , i 9 . 



Back of the rifle range at Paramaribo is a shallow ditch or 

 mud-bedded stream which, on February 23, 191 2, seemed en- 

 tirely dry. However, I followed it for some distance and 

 eventually discovered a few shallow pools of stagnant water. 

 Near one of these pools and in the bed of the ditch lay a large 

 log which for a short distance was a foot or more off the 

 ground ; dense grass grew about the log and thus a little room 

 or cave was formed under the log, the log itself being the roof, 

 the nearly dry mud the floor and the rank grass the sides. At 

 one comer of this little room the grass was wanting, thus af- 

 fording an open doorway. About this doorway and just with- 

 in the little room no less than 50 Aeolagrion dorsale were taken. 

 When I first discovered them possibly a dozen or twenty were 

 in view, practically all of them well back imder the log. At 

 each stroke of the net, those not captured disappeared but in 

 a moment they would be detected again, one here, one there, 

 resting in the grass about the log. Dorsale is an inconspicu- 

 ous species and is ea.sily overlooked in grass. In adjoining 

 woodland I caught two or three about the top of a large fallen 

 tree. I have no notes and recall nothing of the Cumuto speci- 

 mens which were taken at the little swamp where we took 

 the large number of Metaleptobasis (Proc. U. S. Nat. Mus. 

 Vol. 48, May, 1915, p. 6or).

$ ■■ — Genae pale yellowish to pale bluish; labrum slaty blue to bright 

 greenish blue; rhinarium slaty blue to light brown; nasus to ocelli dull 

 orange or rust red. Head above black and dull orange; ocelli sur- 

 rounded with black, except the median in front; on either side of the 

 median is a short lateral black spur, not always distinct ; from each 

 lateral ocellus a black stripe runs forward and outward to meet a 

 wide black area lying against the eye, and reaching inward to the 

 level of the inner side of the second joint of the antenna: anteriorly 

 it extends to in front of the antenna and posteriorly it is carried back 

 over the rear of the head ; it is often dark green in color and is al- 

 ways less intense black than the stripe from the lateral ocellus to the
