880 ZOOLOGY INSECTS. 



elliptical, and not prominent, widely separated. Vertex broad, arcuately 

 deflexed, and passing into the frontal costa without any mark of distinction; 

 the subhexagonal margin faintly outlined ; a very slight median elongate 

 tubercle ; frontal costa broad, flat, rounded on the margins, and scarcely 

 distinct from the face, not sulcate. Pronotum similar in form to that of GE. 

 trifasciata, expanding posteriorly, very slightly constricted or indented at 

 the posterior sulcus, covered throughout, except a small space on the middle 

 of the lateral lobes, with small tubercles, giving it a coarsely granulated 

 appearance, forming thereby a strong contrast with the smooth head ; pos- 

 terior sulcus quite distinct, situated about the middle, and extending upon 

 the sides; the other transverse . incisions obsolete on the dorsurn; median 

 carina obliterated ; lateral carinse rounded and subobsolete ; posterior mar- 

 gin rectangular. Elytra and wings extending but slightly beyond the abdo- 

 men; elytra rather narrow, minutely but densely reticulated, except about 

 one-fifth at the apex, which is transparent, and has regular transverse vein- 

 lets ; axillary vein connects with the anal vein. Posterior femora very 

 broad; lower carina very prominent, but suddenly narrowed near the apex; 

 shorter than the abdomen; anterior and middle femora small and slender. 



Color (after immersion in alcohol). Dullash-brown, varied with fuscous ; 

 head, thorax, and legs almost uniform ; a black puncture at each side of the 

 lower extremity of the frontal costa ; a small black spot at the lower corner 

 of the face ; a few black points on the dorsum of the pronotum. The elytra 

 with four broad transverse fuscous bands, one about the middle of the basal 

 half rather narrow and of regular width, the other three on the apical half, 

 between which are alternate yellow bands ; the anterior of these fuscous 

 bauds quite broad and widening upward (posteriorly) ; apex transparent ; 

 a narrow yellowish stripe along the humeral angle. Base and disk of the 

 wings yellow ; a broad, black, arcuate band along the exterior (posterior) 

 margin, having a small transparent space at the apex. This band should 

 perhaps be called submarginal, as the front portion curves slightly inward, 

 and leaves an apical space, which is traversed by fuscous veins. Posterior 

 femora with a few black dots on the external face, and an indistinct paler 

 ring near the apex ; internal face fuscous on the basal half, crossed by a 

 fuscous band on the apical half, rest yellow. Tibiae and tarsi pale ; spines
