ODOPGA.—TETTIGADES. 4) 
exteriorly, rounded posteriorly, obtusely pointed and rounded, but not meeting interiorly. Rostrum 
not passing posterior coxe. 
Long. 25 millim., exp. tegm. 83 millim. 
Hab. Muxtco (Mus. Berol.). 
Allied to O. montezuma, Walk., but differs by the much smaller size, different 
structure of the face and opercula, colour, markings, &c. 
4, Odopea signoreti. (Tab. I. figg. 10, 10a, 104.) 
Odopea signoreti, Stal, Stett. ent. Zeit. xxv. p. 59. 885°. 
Hab. Mexico 1 (coll. Dist.). 
5. Odopea diriangani, n.sp. (Tab. III. figg. 10, 10a, 108.) 
. Ochraceous and unicolorous, obscurely pilose. Tegmina and wings hyaline, veins ochraceous. Face 
strongly carinate, its width and distance to outer margin of eyes being subequal. Eyes black, ocelli red. 
Pronotum with the lateral margins considerably ampliated and rounded, obtusely and obscurely angulated 
about middle, Mesonotum with two large but obscure obconical spots commencing on apical margin. 
Anterior femora with a strong spine about one third from apex, between which and apex are two smaller 
and much more obscure spines. 
Long. 22 millim., exp. tegm. 69 millim, 
Hab. Nicaragua, Chontales (Janson). 
This species is allied to O. signoreti, St&l, and O. azteca, Dist., from both of which it 
differs by the neuration of the tegmina being unicolorous, by the basal margin of the 
eighth apical area being almost straight and oblique, the ulnar veins abruptly divergent 
at base, and also by the strongly carinate face. 
It is more than probable that some specimens of this species are green, and not 
ochraceous like the form here described. 
6. Odopwa medea. (Tab. I. figg. 2, 2a, 25.) 
Odopewa medea, Stal, Stett. ent. Zeit. xxv. p. 60. 386°. 
Hab. Mexico, Oaxaca !. 
A typical female specimen in the Stockholm Museum is here figured; and Dr. Auri- 
villius informs me that in that collection this species has been placed under the genus 
Zammara. The ulnar veins, however, are distinctly separate at their origin; and I see 
no reason to doubt Stal’s correctness in originally placing it in the genus Odopea. 
TETTIGADES. 
Tettigades, Amyot & Serville, Hist. des Hém. p. 469. 369 (1843) ; Stal, Hem. Afr. iv. p. 2 (1866). 
Tettigades differs from the two preceding genera by not having the basal area of the 
tegmina distinctly quadrangular; the lateral margins of the pronotum are also more 
obtusely rounded; and the venation, especially as regards the relative lengths of the 
ulnar and apical areas, is also very different.
