32. Amblytropidia subhyalina. Dark brownish-fuscous, 

 the head and pronotum obscurely clouded with black, and obscurely, 

 longitudinally vittate above with dull yellowish ; antennas infuscated 

 toward the tip; frontal costa shallowly punctulate, the summit of the 

 head faintly rugulose. Pronotum sometimes dotted with black next 

 the posterior border both of disc and lateral lobes, punctate through- 

 out, both median and lateral carinas distinct; tegmina much longer 

 than the abdomen, obscurely dotted throughout with fuscous spots; 

 wings rather sordid hyaline, slightly fuliginous next the apex, the 

 veins blackish ; hind femora blackish on the fuller parts externally, 

 deepest above ; hind tibias dull yellowish-brown, merging into black- 

 ish on the apical half, especially beneath, the extreme apex pallid and 

 the tips of all the spines black. 



Length of body, cf, 20 mm.; ?, 28 mm.; of antenna?, d", 7.25 mm.; 

 $, 6.5 mm.; of tegmina, cf, 18.5 mm.; ?, 23 mm.; of hind femora, cf, 

 14 mm.; ?, 18.5 mm. 3 d", 1 ?, collected March 10 aud 12, at Dal- 

 las, Texas, by J. Boll. 



33. Gomphocerus virgatus. Pretty uniform brown; a 

 broad, straight, blackish stripe, darkest on the pronotum, extends from 

 above each eye to the outer posterior edge of the pronotum, bordered 

 rather faintly and narrowly with yellowish on the inner side through- 

 out its entire length, and distinctly with yellowish- white externally 

 on the pronotum ; this latter whitish line marks the slightly raised, 

 nearly straight lateral carinas and is minutely edged on either side 

 with black ; the inner border of the broad stripe is marked by an 

 intermediate carina, nearly as high as the median carina, and extend- 

 ing from above the front edge of the eyes to the posterior border of 

 the pronotum ; 1 antennas brownish, infuscated on the apical half, 

 scarcely longer than the pronotum, the joints depressed. Tegmina 

 brown with a narrow green stripe just below the costal margin, fol- 

 lowed by a longitudinal, scarcely disconnected series of fuscous spots, 

 causing in the middle of the tegmina a mottled appearance ; wings 

 pellucid ; legs brownish, the outer surface of all the femora infus- 

 cated along the middle, or, in the case of the hind femora, the upper 

 portion of the thickest parts ; spines black tipped, the outer of the 

 inner, apical, aduncate spines of the hind tibias of great length. 



1 The same is true of G. carinatus Scudd., a species from the Middle States, 

 scarcely differing from this excepting in having decidedly fuliginous wings, becom- 

 ing infuscated on the apical half of the costal area.
