sphagnum, moss and shore grasses. They were numerous about a swampy 
pasture pool in New York. 
Reuter, who created the genus Lampracanthia for Uhler’s crassicornis 
species, stated that though he had never seen S. anthracina Uhler it 
probably should be placed with Lampracanthia crassicornis. The habits, 
the similarity of their eggs and their method of deposition is certainly in 
favor of such a consideration. Yet when one examines Uhler’s coriacea, 
one is justified in believing anthracina more nearly related to it than to 
L. crassicornis.

A. TAXONOMY OF THE HEBRIDZ. 
Family Characteristics. Very small plump bodied insects. The adults 
in the genus Hebrus always winged while those of Merragata are di- 
morphic. Antenne five-segmented in Hebrus, four in Merragata. Ocelli 
present; head and thorax sulcate beneath; rostrum three-segmented; 
tarsi two-segmented. Until recently but one genus was recorded for the 
United States. In February, 1917, Carl Drake added the genus Mer- 
ragata to our fauna with two new species from Ohio. We have thus 
recorded six Hebrids for the United States, four in the genus Hebrus 
and two in the genus Merragata. 
Historical Review. These insects were placed with the group which 
now forms the Gerride (Amphibicorise Duf. and Hydrodromica Fieb.) 
in its broad sense by Brulle 1835, Burmeister 1835, Blanchard 1840, © 
Westwood 1840, Fieber 1851-1861, Barensprung 1860, Walker 1873, J. 
Sahlberg 1875, Saunders 1875 and Kirkaldy 1909. In 1884 Berg placed — 
them beside the above forms. They were treated as relatives to the 
Tingidids by Amyot and Serville 1843, Flor 1860, Douglas and Scott | 
1865, Puton 1875-1899, and by Saunders 1892. Lethierry and Severin — 
1896, Distant 1904, Champion 1898 and Oshanin 1908 placed them be- | 
tween the Aradids and Gerrids (Hydrometride). Herrich-Schaffer — 
classed them with the Lygeids. Handlirsch 1908 appears to derive them 
from the Hydrometrid group and places them next to the Lygeids ac- 
cording to his diagram, although Reuter says this author is uncertain © 
in regard to them. According to Reuter’s table 1910 they arise doubt- | 
fully from the Neidoideew group. The Tingidide are their nearest rela- 
tives within this group. The Coreide lie just beyond in the next group. 
In 1912, Reuter removes them to another series altogether and lists 
the Hebrids under the superfamily Reduvioidiw because of their simi- 
larity to certain Nabids. Horvath, Bergroth and Champion consider 
the Hebrids and Mesoveliids closely related, as does Van Duzee.
