NO. 1124. SEriSIOX OF THK ^ELAXOPLI—SC UDDER, 371 



])ortion of the genae; antennae red, infuscated apieally. Pronotnm 

 subequal, scarcely expanding posteriorly even in the female, the front 

 margin siibtruucate, the hind margin broadly angulate. the angle 

 rounded ; disk very feebly convex and separated by subdistmct lateral 

 carinae formed of a rounded angle from the subvertical lateral lobes, 

 the median carina distinct but slight on the metazo^ia, feeble on the 

 piozona, sometimes subobsolete between the sulci ; prozona smooth, dis- 

 tinctly longitudinal (male) or subtranaverse (female), a third (male) or 

 scarcely (female) longer than the finely and closely punctate metazona. the 

 principal sulcus between them straight; without lighter markings at 

 the lateral carinae, the lateral lobes more or less but feebly discolored, 

 the posterior lobe of the prozona usually the darker. Prosternal spine 

 rather long, moderately stout, subcjiindrical, blui.t, a little retrorse. 

 Tegmina surpassing the hind femora, rather slender, tapering very 

 feebly, brownish testaceous without longitudinal stripes. Fore and 

 middle femora jdumbeo olivaceous, somewhat tumid in the male; hind 

 temora brown or ferruginous above, dark olivaceous on the outer face, 

 dull tlavous beneath and on the inner side, but on the latter more or 

 less interrupted with fuscous above, the genicular arc brownish tes- 

 taceous; hind tibiae wholly coral red, the spines black r^nost to tlie 

 base, ten to twelve in number in the outer series. PLxtr ity of male 

 abdomen feebly clavate, upturned, the supraanal plate triangular with 

 gently sinuate margins, subrectangulate apex, nearly flat, with a very 

 broad and obscure, feebly percurrent, longitudinal sulcus, bounded by 

 low broad walls, a little constricted in the apical half; furcula consist- 

 ing of a pair of slight acumiuate denticulations, arising from the thick- 

 ened inner extremities of the divided halves of the last dorsal seg- 

 ment, and overlying the ridges bounding the median sulcus of the 

 supraanal plate; cerci large and broad, gently incurved, slightly taper- 

 ing on the basal half, and then expanding into a transversely suboval 

 apical flabellation, nearly half as broad again as the extreme base, 

 expanding more above than below, the apical margin broadly convex, 

 the whole considerably surpassing the supraanal plate; infracercal 

 plates surpassing but slightly the sides of the supraanal plate, about as 

 long as it; subgenital plate moderately broad, the lateral margins 

 hardly elevated apieally, but considerably prolonged, subtuberculate. 



Length of body, male, 23 mm., female, 29 mm.; tegmina, male, 20 

 mm., female, 24.5 mm.; hind femora, male, 13.75 mm., female 15.75 mm. 



Three males, 2 females. Los Angeles, California, Coquillett, July 

 (L. Bruner; U.S.N.M. — IJiley collection). 



This is the smallest and at the same time the slightest species in this 

 series. 



28. PrNCTrLATTJS SERIES. 



This group is composed of species with prominent head and rapidly 

 declivent fastigium, and, in the male, very prominent eyes. The joints 

 of the antennae are unusually long. The pronotum is rather short and
