NO. 1215. REVISION OF THE GENUS TRIMEROTROPIS—MmEILL. 399 



/'. Posterior lobe of the crest of the prozone plainly not so high as it is 

 long. Posterior femora very distinctly banded on the 

 outer face, lower sulcus light-colored with two black l)ands. 



alholineata Bruner. 



/-'. Posterior lol)e of the crest of the prozone as liigh as it is long. 



Posterior femora indistinctly banded on the outside, lower 



sulcus ))lack with two light 1)ands cri.s-tata, new sjiecies. 



'■-. Pnizdiie of the pronotum not bilobate when seen from the side and barelv 

 intersected by the sulcus, and therefore straight and l)arely 

 perceptably notched. Median carina cristate on themetazone 

 and nearly as high as on the prozone. .porreda, new species. 

 K Lateral lo])es with no dentation on the posterior part of the lower border, or if 

 there is a blunt tooth present, the fuscous band is weak or 

 interrupted and the pronotum has no definite stripe along 

 the lateral edges of the disk nor is the middle darker than 



the lateral borders Maritim a grocp. 



h'^. Area of the cubital forks of the tegmina occupied by more than one row of 

 irregular cells. 

 '•1. Wings with the median and cubital areas about equal. Larger, male 26 nun., 



female 34 mm. long. North American maritima Harris. 



c'^ Wings with the median and cubital areas verj' unequal. Smaller, male 

 22 mm., female 28 mm. long. Chilean. 



ochraceipennis Blanchard . 

 h'\ Area of the cubital forks of the tegmina narrow, occupied by a single row of 

 subquadrate cells. Lower sulcus of the posterior femora 

 black with a single i^reapical light band. 

 '■'. Median carina on the metazone somewhat cristate. Fuscous l)and of the 

 wings indicated only by infuscated veins, or at most incom- 

 plete and continued on the posterior margin less than half 

 way to the anal angle; spur extending more than half way 



to the base gracilis Thomas. 



c'^. Median carina on the metazone distinct but merely a raised line. Fuscous 

 band of the wings distinct and uninterrupted, continued on 

 the posterior border much more than half way to the anal 

 angle; spur extending less than half way to the base. 



roqitilletti, new species. 

 Tegmina fasciate, with solid well-defined bands reaching at least half way across 

 the wing from the anterior margin, or by the segregation of 

 annulai* spots, fascia sometimes faint on account of the 

 slight contrast between them and the ground color. Rarely 

 the tegmina are not fasciate, then they are evenly maculate 

 with fuscous annuli and the wings are broad with the 

 apical half fuscous or fuliginous. Frontal costa generally 

 sulcate above the ocellus for a short distance only, below 

 the vertex rounded and i)unctate. Pronotum with the disk 

 usually elevated and subtectiform on the prozone. Area of 

 the cubital forks broad, occupied by several rows of irregular 



cells Trimekotroi'is subgenus. 



^ Wings with the disk yellow or green, never l)lue, and never without a fuscous 



' band or cloud. 



h^. Hind tibia? never l)lue. Tegmina with the basal and median bands solid, 



ai)proxiniately equal to each other and to the light bands 



just beyond with which they alternate, and confined to a 



little more than the anterior half Cincta c^roup.
