NO. 1124. REVISION OF THE MELANOPLI SC UDDER. 357 



siderably to an obliquely transverse, broad, oval lobe with regularly 

 rounded contour, above expanding- twice as much as below, the whole 

 feebly incurved and surpassing the supraanal plate ; infracercal plates 

 hardly visible, briefer than the supraanal plate; subgenital plate rather 

 narrow, subequal, abruptly, roundly, and considerably elevated apically, 

 but not produced, entire. 



Length of body, male and female, 25 mm.; antennae, male, 15 mm., 

 female, 12 mm.; tegmina, male, 13.5 mm., female, 9 mm.; hind femora, 

 male and female, 1(5 mm. The female measured has exceptionally short 

 teginina. 



Nine males, 12 females. St. Louis, Missouri (U.S.X.M. Eiley collec- 

 tion); central Missouri (same); Illinois, Uhler; southern Illinois, Ken- 

 nicott, Thomas. 



It has also been reported from central Illinois (Thomas); Kunning 

 Lake, Illinois, July 15. September (McNeill); Anderson, Fulton, Hop- 

 kins and Christian counties and Elk Lick Falls, Kentucky (Garman); 

 southeast Nebraska (Bruner). It would therefore appear to have a 

 rather narrow range, in the central Mississippi Valley, between latitude 

 37-40, and longitude 86-96.

 dull reddish brown, faintly dotted with fuscous; tips of mandibles and 

 lower edge of labruin marked with black; interspace between the eyes 

 a little (male) or much (female) broader than the basal antenna! joint,

 broad, subequal, slightly depressed at the ocellus; antennae luteous, 

 inluscated on the apical half, nearly (male) or about two-thirds (female) 

 as long as the hind femora. Pronotum scarcely enlarging posteriorly, 

 with but slight transverse sulci and a slight median carina, equal and 

 percurrent in the female, interrupted slightly between the sulci in the 

 male; lateral cariuae indistinct, rounded; top of head and pronotum 

 dotted faintly with fuscous, the lateral lobes of the latter paler, marked 

 next the lateral carinae with a black streak, which narrows and dis- 

 appears posteriorly, broadens anteriorly and extends slightly upon 

 the head. Prosternal spine rather long, cylindrical or conico-c} r lin- 

 drical, blunt-tipped, feebly retrorse. Tegmina not reaching the tip of 

 the abdomen, about as long as the femora, the costal field dark testa- 

 ceous, the discoidal field blackish, and the anal field, which is sepa- 

 rated angularly from the rest, light testaceous or wood-brown. Fore 

 and middle legs of the color of the body; hind femora long and moder-
