referred by Hagen to pallid us ('85, p. 267) are of this species. 

 Imagos of spicafus were taken by Mr, Hart at Cedar, Sand, and 

 Fox lakes, June 15-22, 1892. This is its first record from 

 Illinois, it having been previously listed only from Canada, 

 Massachusetts, New^ York, and Ohio. In the latter state it was 

 common in the northern part, flying in June, the latest date, 

 being July 1. Van Duzee found the imago in a swamp. Kelli- 

 cott found it along wave-washed shores, the males flying out 

 over the water, the females, when not ovipositing, remaining 

 on herbage or trees on shore. 



The nymph, not quite fully grown, measures 28 mm.; ab- 

 domen, 18 mm.; hind femur, 5 mm.; width of abdomen, 6 mm.> 

 of head 5.5 mm. 



Body flat, hairy on legs and lateral margins. Color yellow- 

 ish, eyes black; fuscous mottlings at base of wing-cases and on 

 sides of abdominal segments between the yellow mid-dorsal 

 line and the scars, sometimes forming oblique streaks. 



Labium moderate; front border of median lobe nearly 

 straight; lateral lobes short arcuate, with a sharply incurved 

 end hook, on the inner margin 6 to 9 short rectangular back- 

 wardly directed teeth. 



Wing-cases reach the 5th segment. 



Abdomen nearly 3 times as long as wide, lateral spines on 

 segments 7 to 9 increasing in size posteriorly, those of 9 half 

 as long as segment 10. No dorsal hooks; traces of mid-dorsal 

 smooth line apparent on middle segments. Lateral margins of 

 8 and 9 subentire ; segment 10 half as long as 9, Appendages 

 longer than segment 10, the laterals shorter than the others. 



11. Gomphus austral is Needh. 



This is a Florida species, described as new by Mr. Needham 

 ('97, p, 184), Nymphs supposed by him to belong to australis 

 were collected near Gotha, Fla., in December, 1896, and in 

 January, 1897, by Mr, Adolph Hempel, who took a single male 

 imago at the same place a little later. Morphological charac- 

 ters entirely justify their reference to this species.
