sistent mark being a round, blackish spot near the vertex. 

 The labium was much like the previous species, entirely unlike 

 that of sollicitans, but the antennae were longer, different in 

 form, and spiny rather than hairy. The adults seemed to be 

 also sylvestris. Mr, Coquillett has not yet had an opportunity 

 to study these forms comparatively.* 



All the other species bred by me agree generally in having 

 the labium somewhat oblong, the centre a little produced and 

 the line to the side more or less oblique. 



C. territaiis differs from all the others in the enormously 

 long, slender anal siphon and the broad head with prominent 

 antennae extending beyond the sides. These antennae are black 

 at tip and have a tuft of long hair at the set-off. The larvae 

 occur almost everywhere in running or stagnant waters, fresh 

 or brackish ; but 1 have not found them in really foul nor ab- 

 solutely salt water. 



C. pungens is common everywhere in all kinds of water, no 

 matter how foul. I have not found it in salt or even brackish 

 water ; but the addition of sea salt to water in which it was 

 breeding, did not prevent the completion of its transformations. 

 It is a white larva with a moderately long anal siphon a little 

 enlarged at the middle. The antenna is quite characteristic ; 

 stout, a little curved, with a distinct set-off beyond the middle. 



A similar larva is quite generally found in ponds overgrown 

 or otherwise sheltered, and in quiet or even stagnant waters ; 

 but not in salty or foul water. The adult resembles pimgens 

 so closely that I cannot distinguish between them and Mr. 

 Coquillett has called \.\\\s pipiens for me. The antenna in the 

 larva is shorter than in pungens, not curved, not nearly so stout, 

 and the small set off is below the middle. The labium is alto- 

 gether different in shape, as a comparison of the figures will

 On the salt meadows near Elizabeth Mr. Brehme found with 



* Since the above was written Mr. Cocjuillett has compared the species 

 and finds no differences from sylvestris ; but the hirva is certainly not like 

 the Delair species. I think we have close allies or a (liniorpiiic larva. 



t This species is restuaus according to Coquillett who has pointed out 

 to me distinctive characters since the above was written.
