eyes, scarcely wider than the first antennal joint; foveola of vertex 

 narrow, with sides broadening a little in front, pretty sharply de- 

 fined, enclosing a moderately deep sulcus, deepest posteriorly ; frontal 

 ridge rather broad, the sides nearly parallel, fading out below with a 

 sulcus scarcely perceptible, excepting about the ocellus. Pronotum 

 equal, the median carina very slight, most distinct on posterior lobe, 

 cut by every transverse incision; lateral carinae obsolete. Terminal 

 segment of abdomen in male roundly acuminate ; cerci broad at 

 base, scarcely twice as long as broad, subreniform, well rounded, but 

 little smaller on the apical half. Allied to C.flavolineatus.

29. Caloptenus fasciatus. Brownish yellow. A broad dark 

 brown, or blackish median band extends from the vertex between the 

 eyes to the posterior extremity of the pronotum, broadest on the 

 latter, and occupying about one-third of it; besides this another 

 band runs from behind the eye to the posterior transverse sulcus of 

 the lateral lobes of the pronotum ; this is comparatively narrow, but 

 often sends off streaks of blackish fuscous down the incisures; an- 

 tennae yellow, somewhat infuscated apically. Tegmina brownish 

 fuscous, with a row of dusky quadrate spots down the middle of the 

 basal half; legs yellow, tinged with dull orange, the hind femora 

 faintly bifasciate above internally, and with the upper exterior carina 

 black ; hind tibiae glaucous, paler and dull at the apex. Vertex 

 quite as broad between the eyes as the first abdominal joint ; the fas- 

 tigium slender, Avith parallel sides, and rather deeply sulcate; frontal 

 ridge rather broad, equal, scarcely sulcate below the ocellus. Pos- 

 terior lobe of pronotum expanding a little, the median carina scarcely 

 perceptible, excepting on this part of the pronotum, the transverse 

 furrows distinct. Terminal segment of abdomen of male entire, 

 rounded, but a little produced ; cerci rather small, quadrate, squarely 

 docked at tip, nearly equal throughout, but smallest in the middle, 

 strongly compressed, bent inward. 



Length of body, d, 28.5 mm., ?, 26 mm.; of antennae, d, 12.5 mm., 

 ?, 10.5 mm. ; of tegmina, cf, 24.5 mm., ?, 23 mm. ; of hind femora, 

 d", 16 mm., ?, 15 mm. 2 cf, taken July 16, at Dallas, Texas, by 

 J. Boll. 1 ?, taken at Glencoe, Nebraska, by C. R. Dodge. 



It is closely allied to C. bivittatus (Say), but lacks the humeral vitta 

 of the tegmina, and has very different cerci.
