Scudder.] 478 [April 7, 



30. Caloptenus minor. Dark brownish fuscous. Head and 

 sides of pronotum very dark livid brown, mottled obscurely with 

 blackish ; summit of the head with a median blackish stripe ; and 

 another similar piceous stripe behind the eye, extending over the 

 lateral lobes of the pronotum, where it is broader and distinct, as far 

 as the posterior transverse furrow ; antennae dusky yellow. Tegmina 

 wholly similar in appearance to those of C. femur-rubrum ; legs yel- 

 lowish, the femora dusky outside, the hind femora blackish along the 

 middle, the apex black above, dull orange beneath ; the hind tibiae 

 plumbeous, paler toward the tip. Vertex between the eyes about as 

 wide as the first antennal joint, the foveola narrow, equal, deeply 

 sulcate, the sides pretty high and sharp; frontal ridge moderately 

 broad, broadening below, shallowly sulcate below the ocellus. Pro- 

 notum broadening very slightly on the posterior lobe, the median 

 carina slight, equal, cut only by the posterior sulcation; lateral carinas 

 obsolete. Last segment of the male abdomen slightly tuberculate at 

 tip ; cerci with the basal portion stout, quadrate, not very strongly 

 compressed, nearly twice as long as broad; the apical portion of the 

 same shape, but broadly rounded at the tip, nearly as long as the 

 basal part, but narrower, bent from it upward at half a right angle, 

 bent also inward, much compressed and shallowly sulcate, with an 

 inferior bounding ridge. 



Length of body 17.5 mm.; of antennae, 7 mm. ; of tegmina, 12.5

Allied to Tragocephala Harr. Head but little tumid above; front 

 vertical above, roundly declivant below the costa, nearly equal, but 

 broadening and fading on approaching the labrum, a little constricted 

 above the antennae; vertex moderately broad, the eyes being sepa- 

 rated by about their own width, the summit of the head minutely 

 and bluntly carinate as far forward as the middle of the fastigium; 

 the latter somewhat declivant, tapering anteriorly, distinctly though 

 not very deeply hollowed; lateral fastigia triangular, slightly trans- 

 verse, scarcely sulcate ; eyes moderately large, shaped as in Tragoce- 

 phala ; antennae as long as (¥) or much longer than (e?) the combined 

 head and pronotum, the joints flattened, on the apical half punctate.
