on the tipper face, the lower face pale red, the geniculation hardly 

 infuscated; hind tibiae pale testaceous with a faint greenish tinge, 

 especially upon the tipper half, often minutely flecked with fuscous, the 

 spines pallid at base and black at tip, ten to eleven in number in 

 the outer series. Extremity of male abdomen clavate, considerably 

 recurved, the supraanal plate triangular or subhastate with acutaugu- 

 late apex, the lateral margins broadly and gently elevated on the 

 basal half, the median sulcus percurrent, deep basally and gradually 

 shallowing; furcula consisting of a pair of parallel, approximate, slen- 

 der, acuminate spines, less than one-fourth the length of the supraanal 

 plate; cerci small, slender, tapering gently on basal third, beyond 

 equal, nearly straight but feebly incurved, well rounded at tip, much 

 shorter than the supraanal plate; subgenital plate small, subequal, 

 a little longer than broad, the lateral and apical margins in the same 

 plane, angulate as seen from above. 



Length of body, male, 14 mm., female, 18 mm. ; antennae, male, 7 mm., 

 female, 4.75 mm.; tegmina, male, 4.25 mm., female, 4.5 mm.; hind fem- 

 ora, male, 9 mm., female, 10 mm.

 (Plate XVI, fig. 3.) 



Of every small size, fusco-testaceous, the legs and under surface 

 flavous. Head rather prominent, especially in the male, flavous, more 

 or less feebly punctate with fuscous, above with a pair of divergent 

 obscure fuscous stripes; vertex gently tumid, slightly elevated above 

 the pronotum, the interspace between the eyes scarcely (male) or only 

 (female) as wide as the first antenna! joint; fastigium steeply declivent, 

 rather deeply sulcate, broadening anteriorly to double the basal width; 

 face considerably oblique, the frontal costa fading j ust before the clypeus, 

 equal except for a slight contraction above, a little broader than the 

 interspace between the eyes, distinctly sulcate throughout excepting 

 above, feebly and biseriately punctate; eyes large, prominent, much 

 longer than the infraocular portion of the genae; antennae rufo-testace- 

 ous, almost as long (male) or a little more than two- thirds as long 

 (female) as the hind femora. Pronotum subequal on the prozona, flar- 

 ing a little on the metazona, with no piceous postocular band, the 

 lateral lobes short and nearly unicolorous, the disk broadly convex and 

 passing insensibly into the vertical lateral lobes; median carina faint 

 and slight on the metazona, obsolete on the prozona, especially in the 

 male; front margin truncate or subtruncate, hind margin truncate and 

 very feebly and broadly emarginate; prozona distinctly punctate and 

 transversely rugose, at least in the male, subqttadrate, almost twice as 

 long as the densely and rather heavily punctate metazona. Prosternal 

 spine of moderate size, erect, strongly appressed conical; interspace 

 between mesosternal lobes quadrate (male) or transverse but much
