Family VELIID.E. 

 Genus MICROVELIA Westwood. 

 M. americana Uhler ( — Hebrus americanus Uhler) . 



Central Park, N. V. City, March 22; Ft. Lee Dist., N. J., May 2S and Sep- 

 tember 7; Bronx, N. V. City, September 30 ; Staten Id., X. Y.. March 29; Rail- 

 way R., Cranford, N. J., August 6 and 20; Westfield, N. J., July 4, 16, 30, August 

 13, September 2. 



I have placed this insect here, as it is evidently a Microvelia and not a true 

 Hebrus. The generic characters do not agree with those given for the latter genus 

 by Amyot & Serville. The Hemipteron is extraordinarily abundant under the banks 

 of a little stream near Leonia, and this spring I found it on another little stream at 

 Fort Lee. It appears to prefer running water. Out of a long series I obtained 



only one fully winged individual. In the N. J. List, Prof. Smith gives it from 

 "Atlantic States" fide Uhler. In another little stream in Westfield, in a little 

 bayed-in place and under the overhanging banks, took several more winged individ- 

 uals. They were abundant in all the places cited, and rest usually on the shore or on 

 floating logs at the water's edge, onto which they run on being alarmed, returning 

 immediately to the shore. 



M. pulchella Westwood. 



Staten Id., May 5 and August 16. Ft. Lee, N. Y., July 18. 



I have taken but few specimens of this form, two of those taken this spring on 

 Staten Id. being winged individuals. This species is lacustrine, and to be found 

 running on Lemna. 



I have also taken what are apparently three other species of the genus, one near 

 M. americana Uhl., and the other two near M. pulchella Westw., but have not been 

 able to determine them, due to absence of literature. 



Genus MESOVELIA Mulsant. 



M. mulsanti White ( =M. bisignala Uhler).* 



Ft. Lee Dist, N. J., August 20 and 22, September 7 and iS; Putnam Co., 

 N. Y., September 5 ; Staten Id., N. Y., August 16 and September 26 ; Van Cort- 

 landt Pk., N. Y. City, August 15, September 19 and October I ; Westfield, N. J., 

 June 26, July 3 and 9, September 2 ; Railway R., Cranford, N. J., August 6 and 27. 



This is very abundant on Lemna, in still waters. I have taken it in the three 

 forms, fully winged, brachipterous, and apterous, the last being the most abundant. 

 This is a most widespread bug. It is recorded from the greater part of the continent, 

 the Antilles, and as far down as the Amazon River. In the Railway River at < Iran 

 ford and in general in that district, the winged form is much more abundant than I 

 have seen it elsewhere. 



Genus RHAGOVELIA Mayr. 

 R. obesa Uhler. 



Lakehurst, N. J., July n, September 5 and October iS; Rahway R.. Cranford, 

 N. J., August 6, 20 and 27.
