 PL X, figs. 12-13. 



Fuscous or blackish-brown, head and keels yellowish fuscous. 

 Antennae and legs fuscous. Pronotum and scutellum dirty 

 yellowish-grey, middle keel and posterolateral margins of the 

 latter sometimes very narrowly ])ale, two obscure pale lungi- 

 tudinal stripes. 



Head dorsally longer than wide, produced a little in front 

 of the eyes, vertex with a keel down the middle. Frons a little 

 broader apically than basally, keels distinct, but filiform. An- 

 tennae reaching beyond the base of the clypeus, segments nearly 

 subequal in length. Pronotum with lateral keels fairly straight 

 but very divergent, not reaching the liind margin, but continu- 

 ing parallel with it in the form of 2 or 3 granules, hind margin 

 very obtuse-angularly emarginate. Tibial spur with about 16 

 well developed spines, first segment of hind tarsi longer than 

 the other twQ. 



Loig-ivinged form: Scutellum about twice as long as prono- 

 tum. Tegmina hyaline cinereous, with 7 apical cells, generally 

 unforked (this varying in the same individual), veins feebly 

 granulate, pale yellowish fuscous. 



Slwrt-zi'iiigcd form: Scutellum shorter than pronotum. Teg- 

 mina reaching to about one-half of the length of the body, hya-

 lowish fuscous, concolorous, polished and shining, parallelsided, 

 the keels filiform and not ]irominent. First antennal segment 

 about three-fourths the length of the second. Lateral keels of
