NO. 1124. EEriSIOX OF THE MELANOPLISCUDDEE. 275 



very long, appressed conical, blunt, erect; interspace between mesoster- 

 nal lobes a little longer than broad (male) or distinctly transverse but 

 narrower than the lobes (female). Tegmina abbreviate, about as long as 

 the pronotum, attingent, elliptical, but attenuate basally, well rounded 

 apically, a little less than twice as long as broad, dark brownish fuscous. 

 Fore and middle femora somewhat tumid in the male; hind femora not 

 very slender, blackish fuscous on the upper two-thirds of the outer 

 face inclosing a small median testaceous spot, fuscous on the upper face 

 externally, with the outer carina dull flavous, the inner face and inner 

 half of upper face flavous more or less broadly bimaculate or bifasciate 

 with fuscous, the lower third of outer face flavous, becoming pale orange 

 below like the lower face, the genicular arc black and the lower genicu- 

 lar lobe more or less infuscated; hind tibiae pale red or glaucous, pallid 

 at extreme base, the spines black on the apical half, nine to eleven in 

 number in the outer series. Extremity of male abdomen strongly 

 clavate, strongly recurved, the supraanal plate concealed in the single 

 specimen seen ; furcula consisting of a pair of very distant, very slight, 

 parallel spines, shorter than the last dorsal segment; cerci large and 

 broad, wholly inbent, subequal laminae, somewhat and not very broadly 

 constricted in the middle, the apical portion as broad as and longer than 

 the basal, and broadly and angularly sulcate, apically angulate, the 

 whole somewhat more than twice as long as broad ; subgenital plate 

 somewhat longer than the basal breadth, subequal except for the ele- 

 vation of the apical margin, which, as seen from above, is transverse, 

 entire, and makes the apical breadth equal to the length. 



Length of body, male, 17.5 mm., female, 22.5 mm.; tegmiua, male and 

 female, 4.5 mm. ; hind femora, male and female, 11 mm. 



One male, 1 female. Magdalena, Socorro County, New Mexico, July, 

 F. H. Snow (University of Kansas). 



The antennae of both specimens are imperfect. The species is named 

 for Chancellor F. H. Snow, of the University of Kansas, and Mr. W. A. 

 Snow, of the same institution, father and son, entomologists of note. 



19. FEMUE-EUBEUM SEEIES. 



This is a dominant and homogeneous group of medium or rather small- 

 sized species, in which the male prozona varies from slightly transverse 

 to slightly longitudinal, and the interspace between the niesosternal 

 lobes in the same sex is as in the spretus series. The tegmiua are 

 always fully developed or a little abbreviated (so as to fall a little 

 short of the tip of the hind femora), immaculate or slightly maculate 

 along the middle line. The hind tibiae are normally red and have ten 

 to fourteen spines in the outer series. 



The supraanal plate is clypeate, longer than broad and mesially con- 

 stricted. The furcula consists of a pair of parallel or nearly parallel, 

 long or moderately long, generally separated, slender, tapering, sub- 

 cylindrical fingers or spines. The cerci are compressed subfalcate
