SUBFAMILY VI. — ECTRICHODIIN^. 561 



nymphs of this species, I have happened upon but one adult, 

 from which the above description is drawn. In Indiana the 

 nymphs occur beneath logs or stones, usually in damp places. 

 In Florida the adult and nymphs have mostly been found be- 

 neath boards along the margins of ponds, though one nymph 

 was taken from the flowers of Garberia fruticosa (Nutt.). It 

 has been recorded only from St. Petersburg, Clearwater and 

 Enterprise, that State, Van Duzee having taken one at electric 

 light in Clearwater, which "bit viciously when captured, pro- 

 ducing a wound as painful as that inflicted by the Notonectas." 

 The nymphs of all stages have the ocelli wanting and are 

 largely reddish-yellow in hue, only the head, wing-pads, some 

 spots on abdomen, and antennse being darker. The known 

 range of this bug extends from New Jersey west to Michigan 

 and southern Illinois, and south to Florida, Texas, California 

 and Mexico. But little regarding its habits has been recorded, 

 the majority of specimens mentioned having been taken at 

 light. 



Subfamily VI. ECTRICHODIIN^E Amyot & Serville, 1843, 342. 



Medium sized oval or elongate-oval species having the head 

 porrect, declivent in front, its hind portion constricted to form 

 a distinct neck; antennse 8-jointed, the usual third joint being 

 divided into two, and the fourth joint into four; pronotum 

 constricted slightly in front of middle, its disk with an im- 

 pressed median line and hind lobe with a groove each side ; 

 scutellum broad, its apex ending in two short decurved spines ; 

 elytra of females often much abbreviated, in males usually 

 reaching tip of abdomen ; connexivum widely exposed and re- 

 flexed ; spongy pad of front and middle tibiae very short. The 

 species are chiefly tropical, the majority of them inhabiting the 

 Old World. Of the six American genera but two have been 

 recorded from North America, and one of them probably 

 erroneously.'" 



I. Rhiginia Stal, 1859b, 176, 181. 



Oblong-oval spcies having the hind portion of head short, 

 hemispherical, the ocelli placed on the sides of a small eleva- 



6S Stal (1864a, 59) described Pothcn ceneo-nitena from a specimen in the Signoret 

 collection labelled "America borealis." Later (1S72, 104) he said: "In America 

 boreali vix occurrit." Uhler in his Check List recorded it from the "Southern States," 

 and Banks in his Catalogue from the "western states." Xo other record of its oc- 

 currence in this country can be found and, since apparently no other specimen is 

 known, it is not included as a member of our eastern fauna.
