85 (121). Euschistus euschistoides (Vollenhoven) , 1868, 180. 



General form that of servus, the abdomen apparently a little nar- 

 rower, due to the less exposed connexivum. Color much as in servus, the 

 fuscous punctures more dense along the side margins of the pronotum; 

 antennae with last two joints more distinctly fuscous; membrane with 

 fuscous dots more numerous and distinct; under surface usually more 

 strongly tinged with pinkish. Front of head cleft, due to the longer, 

 more pointed cheeks which surpass the tylus by a distance equal to or 

 greater than the mean width of the latter. Pronotum with humeral 

 angles usually more broadly rounded. Length, 12 — 14 mm.; width, 

 7 — 8.5 mm. 



Frequent throughout Indiana, April 21 — Nov. 28; apparently 

 more so in the northern counties. Occurs in summer and early 

 autumn on foliage and flowers of various kinds, especially those 

 of dogwood, wild hydrangea, goldenrod, thistle, etc. ; in late 

 autumn and early spring, beneath dead leaves and under bark. 

 This is the species described by Uhler (1871, 96) as Euschistus 

 fissilis, and it is referred to by most authors under that name. 

 Kirkaldy (1909, 64) placed Uhler's name as a synonym of the 

 Diceraeus euschistoides of Vollenhoven. In this he has been fol- 

 lowed by Van Duzee (1917) and subsequent authors. It ranges 

 from Quebec and New England westward across southern 

 Canada and the northern United States to Vancouver's Island, 

 Montana and Colorado, but not yet known from the Pacific 

 Coast States unless Uhler's (1876, 286) California record of 

 servus rightfully applies to it. The most southern localities 

 recorded are Wilkesboro, N. Car. (Englehardt, 1910, 148) and 

 New Jersey, "throughout the State, May — October, the most 

 common species" (Smith, 1910, 15). South of the Ohio River 

 and westward at about the same parallel it is apparently re- 

 placed by servus. 



It is very easy to separate specimens of euschistoides taken in 

 northern Indiana from typical examples of servus from the 

 southern states, but numerous individuals occur in southern 

 Indiana which appear to intergrade, the cheeks being distinctly 

 longer than tylus, yet shorter than in those from the northern 

 counties, the connexivum narrowly exposed, not wholly covered 

 as in those from the north nor broadly exposed as in typical 

 servus and antenna? often wholly pale. It is my opinion that a
