The species ranges over all the Eastern States south to Florida 

 and west to the Mississippi. It has been found in Colorado and 

 is said to occur in Texas. The southwestern records, however, 

 should be confirmed by careful study. 



Microvelia. fontinalis n. sp. — Apterous form : Head nearly as broad as 

 long; white pile next to eyes. Eyes round, small, prominent, black; ocelli 

 close to eyes. 



Antennae nearly half as long as the entire insect; joints i and 2 sub- 

 equal, I shortest, 3 longer than 2, 4 longest; joint i stoutest, 2 following, 

 3 slender and 4 stouter than 3, fusiform; all joints more or less pilose, 

 especially 4. 



Thorax longer than first three dorsal abdominal segments. Femora in 

 all three pairs of legs stouter than tibiae, hairy, all tibiae straight. Femora 

 flavous toward base, tibiae entirely fuscous. 



Six abdominal dorsal segments visible, first and second dorsally with 

 lateral patches of fine blue-gray pile ; five and six with a median large 

 patch, nearly covering the entire segment; all segments margined with 

 black ; first four segments brown above ; all segments a lighter brown on 

 the underside, covered with a sericeous pile. Connexivum strongly re- 

 fiexed in both sexes, more so in the female ; spiracles visible at connexi- 

 vum ; male genital segment not very prominent. General color fuscous, 

 strongly pilose. 



Type, female taken at White Plains, Westchester Co., N. Y., June 30, 

 igi2; paratypes, four specimens same place, same date, two Westfield, 

 N. J., September 3, 1904. 



Long., 2.3 mm. ; lat., i.i mm. at widest part. 



Only the wingless form is known. It was taken in numbers in 

 a spring in a marshy woodland, where it clings to the long mosses 

 growing into the water or walks about leisurely a short distance 

 from the rocky sides of the basin. The blue-gray patches' of 

 pubescence on the dorsum are distinguishing characteristics. The 

 characters given distinguish it from M. americana, for small 

 specimens of which it might be mistaken. In antennal structure 

 it is near M. albonotata.

 for the apterous form. 



Apterous form : Connexivum strongly refiexed, with brown patch on 

 each segment; dorsum black, except three last abdominal segments, which 

 are broadly greenish, the last entirely so. Genital segment large, promi-
