92 JAMES A. G. REHN. 



basally, acuiiiinatc, about one and one-half times as long as the head. Pronotuni 

 with the three carina; distinctly visible, the lateral ones strongly sinuate half 

 way between the anterior margin and the transverse sulci, parallel on the meta- 

 zona; anterior border truncate, posterior broadly rouuded ; lateral lobes with the 

 anterior and posterior margins moderately converging, inferior margin straight 

 posteriorly, moderately ascending anteriorly ; lateral lobes of the metazona and 

 the median area of the prozona coarsely punctate. Tegmina shorter than the 

 abdomen, reaching the base of the sexual appendages, fairly broad ; the expan- 

 sion of the costal area much greater than in Syrbula. Hind femora comparatively 

 slender, exceeding the abdomen, with all the carinaj well marked ; hind tibige 

 with seventeen spines in the outside row. Interspace between the mesosternal 

 lobes slightly broader than long; of the metasternal l(il)es longer than luoad, 

 deeply impressed. 



General color light green, abdomen and nnder surface brown, suffused more or 

 less strongly with purplish red. Median streak on head light purplish (approach- 

 ing solfarino), flanked by a deep green, then the general color into which it shades 

 off, the dividing line between it and the median streak being a faint blackish 

 line. Eyes wood-brown, flecked with l>lackish. Postocular streak narrow, deep 

 purplish red, not reaching the anterior border of the pronotal lobes. Dorsum of 

 pronotuni with the median carina the same as on the head ; lateral caringe ochra- 

 ceous, with a black internal border, which shades off into the general color, the 

 border being absent where the carinpe are most approximate, the external border 

 at this spot having a trace of black. Lateral lobes with a streak of purplish red 

 on the prozona, the streak deepest anteriorly. Tegmina with a streak of light 

 purplish red along the anal vein, expansion of the costal area deep purplish 

 brown ; the tip and part of the radial and ulnar area membranaceus. The gen- 

 eral tint of the tegmina on the discoidal and inferior radial area tends towards a 

 bluish green. Anterior and median pair of limbs i)urplish red. Posterior femora 

 light greenish, with the lateral and superior face iufuscated with dull blackish, 

 strongest superiorly ; genicular lobes deep i)urplish red. Posterior tibia; purplish 

 red, spines pale yellowish, with black tips. 

 Measurements: 



Length of body 33 mm. 



Length of tegmina 20 " 



Length of hind femora 19 " 



Orpliiilella aeiiloala n. sp. 



Types: two specimens; male and female, Cuernavaca, jNIorelos, 

 xi and vi.* 



A})parently allied to 0. pratonim Scudder, but differing in the 

 form of the fastigium, the color of the post ocular stripe and the 

 tegmina. 



Form rather slender. Fastigium acutc-angulate ; lateral carinse prominent; 



interspace deeply excavated ; median and posterior sections of the head with a 



'faint median carina. Facial angle vertical to the antennse, then retreating 



strongly. Frontal costa strongly constricted at the vertex, slightly expanded at 



* The date xi of one specimen, I think may be an error of mine in copying 

 the original, and probably should be vi.
