310 THE CANADIAN ENTOMOLOGIST. 



Genitalia : female, ultimate ventral segment nearly four times 

 wider than long, posterior margin slightly emarginate with a short broad 

 median tooth ; male valve broad, short ; plates broad at base, concavely, 

 attenuately pointed, two and one-half times longer than valve, equalling 

 the pygofers, which are thickly beset with stout hairs. 



Described from two females and two males from Holly, Colo. 

 The small size and the black spot near the anal angle of the elytra 

 at once distinguish this species. 



Lonatura salsura, n. sp. 



Form and general appearance of (ataiitia, but much larger. Pale 

 sordid yellow. Length : 9 4 5 nim., $ 4 mm.; width 1.25 mm. 



Macropterous form : vertex broad, obtuse, convex, one-half longer 

 on middle than against eye, one-third wider than long, anterior margin 

 rounding; front very broad above, rapidly roundingly narrowing to the 

 long parallel margined clypeus ; pronotum one-fourth longer than the 

 vertex, as wide as the eyes ; elytra slightly longer than the abdomen in 

 both sexes, broadly overlapping behind clavus, appendix well developed, 

 nervures indistinct, veins on clavus connected, anteapical cells very 

 long, parallel margined, their apices truncate. 



Brachypterous form : as above except that the abdomen is elongate 

 and the elytra very short, truncate, only covering the first abdominal 

 segment, the exposed part being one-half the whole length of the insect. 



Colour : pale sordid straw in the brachypterous form, macropterous 

 form washed with brownish olive on the head and pronotum, tergum 

 fuscous, partly visible through the hyaline elytra ; below dark fuscous 

 except the face. In dark speciuiens, there are a pair of spots at the 

 apex and an oblique pair near the base of the vertex. 



Genitalia : female, ultimate ventral segment slightly emarginate 

 either side of a prominent median tooth, which is as long as its basal 

 breadth, the lateral angles deeply excised, displaying a rounding lobe of 

 a membrane beneath ; male valve rounding, almost concealed by the 

 ultimate segment, plates concavely acuminate, longer than ultimate 

 segment, equalling the pygofers. 



Described from numerous specimens collected at Ft. Collins and 

 a few from Holly and the Little Beaver, Colo. 



COLEOPTERA IN SEPTEMBER. 

 Stone-turning on the hillsides and in the woods, usually productive 

 late in the season, gave very poor returns this year. However, on 

 September 17th, a brother entomologist and the writer visited a locality 

 which would satisfy the most exacting collector. Where the Chicopee 

 River empties into the Connecticut, a depression in the low meadow- 

 land marks the course of a former branch of the river. The spot is 

 well wooded with poplars, willows and maples, in whose dense shade
