2. T. ustulipunctata. New sp. 



Form similar to tbat of T. elUptica, Germar, but a little more slender; 

 color clear brunneous, with the longitudinal veins wide apart, straight, 

 curving down at tips, with only a few cross-veins, and those chiefly 

 near the tip. Head ochreous, subquadrate, a little transverse, tinged 

 with fuscous, the lateral and posterior edges prominently carinate, pale 

 yellowish, roundedly emarginated on the posterior margin, and angu- 

 larly produced on the anterior margin; front subquadrate, much longer 

 than broad, a little arcuatedly dilated, the lower angles bent inward; 

 superior angles subrectangular ; disk with an oval ochreous spot, the 

 surrounding surface fuscous, dotted with pale yellow ; middle ctirina 

 high superiorly, the lateral carinate edges prominent, pale ; cheeks pale 

 ochreous; epistoma shorter than the front, acutely triangular, ochreous, 

 infuscated on the disk, excepting the middle line ; rostrum reaching to 

 the posterior coxse, the tip piceous. Pronotum short, pale ochreous, 

 a little infuscated, the center with two impressed points, and the sides 

 with a few pale granules, the anterior margin acutely triangular, the 

 posterior margin truncated ; mesonotum longer, embrowned on the disk, 

 striped with yellow on the sides; pleural pieces ochreous, brownish on 

 the disks, the anterior piece with a large round black spot behind the 

 eyes; metasternum greenish-white. Legs dull ochreous, the spines and 

 tarsi more or less piceous, anterior and middle coxae bright crimson. 

 Hemelytra a little flattened, long, and much narrowed posteriorly, the 

 apex obliquely truncated; surface with short, golden pubescence; three 

 round black spots behind the base arranged in a triangle, and near the 

 tip three others similarly arranged ; costal areole with several piceous 

 irregular spots, the transverse veins indistinct, pale, but extending 

 along its whole length ; wings a little embrowned, the nervures darker. 

 Venter and tergum pale ochreous, banded with l)rown, the margins of 

 the segments yellowish-white, the sides of genital segments striped with 

 fuscous. 



Length to tip of hemelytra, 8 millimeters. Width of pronotum, 3 milli- 

 meters. 



Inhabits Cuba (Professor Poey and Charles Wright) and Mexico. 



It resembles T. elUptica, Germar, but has a longer front, and lacks the 

 carinte, which bound a central disk in that species. 



DiCTYONissus. New gen. 



Aspect of Mijcterodus; the upper surface hispid. Vertex subquad- 

 rate, deeply scooped out, a little wider than long, prominent, the ante- 

 rior angles rectangular, and with the bounding carinate lines high, the 

 anterior margin arched in the center ; front longer than wide, the sides 

 convexly curved, the middle line carinated from the tip for about two- 

 thirds of the length downward. Pronotum acutely triangularly nar- 

 rowed anteriorly, and carried forward almost to the front line of the 

 eyes, and deeply emarginated behind ; mesonotum as long as the head 

 and pronotum united, with the ajjex of the scutellum broad and bluntly 

 rounded. Tibiae grooved on the outer face, the posterior pair having 

 three small teeth, exclusive of the apical one. Hemelytra long and nar- 

 row, vitreous, hispid, regularly parabolic on the costal margin, from the 

 base to the inner apical angle, the inner margin straight ; the whole 

 surface filled with net- work of large rounded areoles composed of very 

 coarse nervures, arranged somewhat longitudinally, but obliterating 

 the usual series of longitudinal nervures; the costal area obliterated, 

 excepting only at the base.
