700 FAMILY VIII. GRYLLID.E. THE CRICKETS. 



333b. GBYLLUS ASSIMILIS SCUDDERIANUS Saussure, 1874, 402. Scudder's 

 Field Cricket. 



Size small to medium; form rather slender. Color much as in firm us, 

 tegmina usually paler reddish-brown; hind femora sometimes with apical 

 half of inner and outer faces blackish; abdomen shining black. Head but 

 little if any wider than pronotum, the latter with hind margin truncate, 

 lower margin of lateral lobes shorter and more curved than in firmus. 

 Tegmina covering about two-thirds of abdomen, female, or more, male 

 Wings very narrow, shorter than tegmina. Hind femora proportionally 

 slender. Hind tibiaa with dorsal and median inner apical spurs subequal in 

 length. Inner terminal spur of basal segment of hind tarsi slender, only 

 half the length of last segment. Ovipositor longer than body, one-half 

 longer than hind femora. Length of body, $ and $, 14 15; of pronotum, 

 3.5 4; of tegmina, $, 8 9, 9, 78; of hind femora, $, 910, $, 10.5 

 11.5; of ovipositor, 14.5 16.5 mm. 



Lake, Marshall, Fulton and Vigo counties, Ind. (W.K.R.}. 

 This is the (}. arcnaceus of my former work (1903, 443). Tt is 

 rather plentiful in the sand dime region of northern Indiana, 

 where it occurs in September and October beneath cover in dry 

 bare sandy places- The reddish-brown hue of tegmina, legs and 

 cerci usually contrasts strongly with the deep black of pronotum 

 and abdomen. R. & H. (1915c) have made firm us a synonym of 

 scudderianus, but as Saussure gives the measurements of the lat- 

 ter as length of body 14, hind femora 9 and ovipositor 14.5 mm., 

 I believe that his name does not rightfully belong to as large a 

 varient as firm us, though the two forms probably merge, through 

 C. rumens Scudd. (1902a, 295) which R. & H. also place under 

 scudderianus, 



The range of the form scudderianus is open to question. Saus- 

 sure's types were from "!' Amerique Septentrionale" without 

 more definite locality. Scudder considered it a form of abltreria- 

 tus, i e., luchiosus. If ntbens be taken as a connecting link over- 

 lapping scudderianus in the north and firm us in the south, 

 the distribution of scudderianus, sensu strictu, may be said 

 to be limited to the sandy districts of the northern and eastern 

 states. As arcnaceus it has been recorded by Kostir from Cedar 

 Point, Ohio, and reported by Hubbell (Ms.) from Cheboygan 

 Co., Mich- 



333c. GRYLLUS ASSIMILIS LUCTUOSUS Serville, 1839, 335. Common Field 

 Cricket. 



Size medium to large for the genus; form very robust. Black, often 

 tinged with rusty brown; head and pronotum shining black; tegmina 

 usually a dark reddish- or fuscous-brown, sometimes pale brownish-yel- 

 low; hind femora black or dark reddish-brown, the basal third of under
