REVISION OF THE MEL ANOPLISC UDDER. 23 



band behind the middle of the eye blackish fuscous; whole face and 

 lower part of genae punctate; antennae fnsco-ferruginous. Pronotum 

 blackish fuscous on prozona, ferrugineo-fuscous on metazoua, the upper 

 portion of the lateral lobes with a broad blackish band, on the ineta- 

 zona curving slightly downward and fading out, sometimes edged 

 above anteriorly by a feeble, dull luteous stripe, but beneath sharply 

 denned from the dull luteous remainder of the lateral lobes, this band 

 often subobsolete in the female, or scarcely distinguishable from the 

 disk; metasternal epiinera with an oblique luteous stripe. Tegmina 

 dark fuscous. Fore and middle femora luteo-fuscous or fusco-luteous; 

 hind femora with the outer face greenish plumbeous, the upper face 

 ferruginous, the lower luteous, the inner luteous in the lower, fuscous 

 in the upper half, the whole geniculation fuscous; the hind tibiae blue- 

 green, fusco-ferruginous at extreme base and tip, the spines black- 

 tipped. Supraanal plate of male subclypeate, tapering gradually, the 

 broadly subtruncate tip very obtusely angulate, the sides feebly con- 

 cave, with a median tectate ridge which divides in the basal third to 

 include a narrow,- triangular, rather deep sulcus; furcula consisting of 

 a pair of inconspicuous rounded lobes, formed by the slight fullness of 

 the interior angles of the divided halves of the last dorsal segment; 

 cerci broad at base but at once narrowed by the abrupt excision of the 

 lower margin, so as to be less than half the basal breadth, the apical 

 portion subequal, subfalcate, the lower apical angle acute, the whole 

 laminate, scarcely incurved. 



Length of body, male, 13 mm., female, 17 mm.; antennae, male, 5.5 

 mm., female, 6 mm.; tegmiua, male, 2 mm., female, 2.8 mm.; hind 

 femora, male, 8 mm., female, 10 mm.

5. CONALCAEA, new genus. 

 (xGoro 1 :, cone; 'ahxai'a, tail.) 



Body rather stout, somewhat compressed, slightly (male) or distinctly 

 (female) largest at the metathorax, thinly pilose. Head moderate, 

 slightly prominent in the male only, with the eyes about as broad, in 

 the male, as the metazona; vertex gently convex, scarcely elevated 

 above the level of the pronotum, the fastigium descending rapidly, the 

 face retreating slightly; eyes large, not very prominent, little more so 

 in the male than in the female, longer than (male) or not quite so long 

 as (female) the posterior intraocular portion of the genae, broad oval, 

 hardly more than half as long again as broad in either sex; interspace 

 between the eyes rather narrow, similar in the two sexes, scarcely nar- 

 rower than the frontal costa, which is subequal, more or less sulcate, 

 and fails to reach the clypeus; antennae slender, rather long. Pro-
