carina ouly slightly prominent, equal, cut distinctly in advance of the 

 middle, the lateral carinte delicate, feebly elevated, briefly parallel just in 

 front of the middle, but widely divergent in advance, as behind; lateral 

 lobes with subdued corrugations at the shoulder just below the lateral 

 carinte. Color fusco-cinereous, the head testaceous with pallid gense, 

 jDlumbeo-fuscous above ; antennae testaceous interrupted with fuscous ; 

 pronotum nearly uniform obscure fusco-testaceous, the carina^ concolor- 

 ous ; tegmina cinereous much flecked with fuscous especially in quadrate 

 patches along the median area, one beyond the middle larger than the 

 rest and divided by an oblique pallid bar ; wings hyaline with black 

 veins ; hind femora cinereo-testaceous with a ferruginous tinge and 

 blotched with fuscous, above rather obscurely trimaculate with fuscous ; 

 hind tibice pale ferrugineo-luteous, deepening in tint distally. 



Length of body, 22.5 mm.; antennse, 5.75 mm.; tegmina, 19.5 mm.;

8. The Species of Aulocara. 



Aulocara Scudd. has as synonyms Qildocara Scudd. and Coloradella 

 Brunn. (See Can. Ent., XXIX. 75^ and Psychej VII. 71.) No species 

 have been referred to the last named, but to the others five nominal spe- 

 cies have been referred; elliotti Tliom., ccBi'uleipes Scudd., decens Scudd., 

 strangrdatiun Scudd., and scudderi Brun. Scudderi, as has been shown 

 by McNeill, belongs to Ageneotettix (Eremnus). The other four all 

 represent a single species, which must bear the oldest name, eJUotti. 

 Nevertheless we possess four species which may be separated by the fol- 

 lowing table : — 



Tahle of the Species of Aulocara. 



u^. Fastigium of vertex broader than long, its front margin obtusangulate ; meta- 

 zona feebly tumescent, its hind margin not very broadly obtusangulate ; hind 



tibiae red rufum sp. nov. 



fl'2. Fastigium of vertex at least as long as broad, its front margin rectangulate or 

 acutangulate ; nietazona plane or nearly plane, its hind margin broadly obtus- 

 angulate; hind tibiaj purple,* or glaucous. 



61. Pronotum strongly constricted mesially, the disk with more or less conspicu- 

 ously decussate markings, the lateral carinae strongly divergent in front and 

 behind. 



c^. Male antennae as long as thorax and abdomen combined ; lower margm of 

 lateral foveola; of vertex obsolete or obsolescent ; tegmina generally immacu- 

 late, much shorter than the long hind femora femoratiim sp. nov. 



* The hind tibial oi A. parallelum are not known, but are presumably purple.
