NO. 1124. REVISION OF THE MELAyOPLI—SCUDHEli. 291 



lobes latlier apijroxiinate (male) or moderately distant (female). Tej?- 

 miiia failing a little (male) or considerably (female) of reacliiiiff the tips 

 of the hind femora, moderately br <^d, distinctly taperiiijjf, stronjjfly 

 rounded at apex, fusco-ferruginous, imraacnlate; winj^s not broa<l, 

 iinpme hyaline with reddish fuscous veins. Fore and middle femora 

 considerably tumid in the male; hind femora varying from dark testa- 

 ceous to dark plumbeo-fuscous, the inner half of the upper face dull 

 tlavous, with the base, geniculation, and two large intermediate spots 

 black, the under surface deep red; hintl tibiae deep red, often much 

 infuscated but then with a narrow, red, subbasal annulus, the si>ines 

 black throughout, eleven to twelve, usually eleven, in number in the 

 outer series. Extremity of male abdomen strongly clavate, somewhat 

 recurved, the supraanal plate long ( lypeate, with sides strongly com- 

 pressed in the midille, the lateral margins strongly elevated, tlu apex 

 acutangulate, the median sulcus very narrow and deep, bein„ a mere 

 slit between moderately high but rounded walls, apically obsolete; 

 furcula consisting of a pair of basally attingent, basally expanded, and 

 di'pressed fingers, wliich beyond are straight, parallel, acuminate 

 thorns, more than a third as long as the 8uj)raanal plate and overlying 

 its ridges; cerci coarse and heavy subfalciform laminae, their planr? 

 obli(iuely vertical and nearly straight, considerably shorter than the 

 sui)raanal plate, tapering consider-^bly on the basal half, feebly on the 

 apical half, which is considerably more than half as broad as the 

 extreme base, obhquely truncate at apex, the upi)er angle very blunt; 

 subgenital plate narrowing from base to apex, somewhat longer tlian 

 broad, the lateral margins gently sinuate, the apictal margin elevated 

 by slight tubercles at its somewhat angular junction witii the lateral 

 margins, so that it is broauiy notched, as viewed posteriorly. 



Length of body, male, 17.5 mm., female, 23 mm.; antennae, male, 

 8.25 mm., female, 0.75 mm. ; tegraina, male, 12.25 mm., female, 11.5 mm.; 

 hind femora, male, 10.5 mm female, 11.5 mm. 



Two males, 2 females. Above timl er line on Sierra Blanca, Colorado, 

 12,000 to 13,000 feet (S. IT. Scudder; L. Bruner). All the specimens, 

 besides two i)upae, taken by me August 29, 1877. 



The species is very closely allied to the last, but ditt'ers from it dis- 

 tinctly in the character of the subgenital plate. 



'' :]:.-'^^^^^^^^ 20. CIXEKEUS SERIES. ^'V' ''■' --''_^-\'\ 



In this more than usually homogeneous group, the male prozona is 

 quadrate or slightly longitudinal, and the interspace between the 

 mesosternal lobes of the same sex varies from a little longer than broad 

 to twice as long as broad. The tegmina are always fully developed, 

 surpassing somewhat the hind femora, and at most are feebly maculate, 

 the flecking not always confined closely to the discoidal area. The 

 liind tibiae are blue or green (in one instance apparently reddish yellow) 

 and have ten to twelve spines in the outer series.
