 tip : pectus testaceous ; sternal ridge lanceolate, extending to the first 

 cosfe, its posterior extremity concave, contiguous to the broad, round, 

 ventral spine, abdomen blackish: beneath piceous, very thickly and finely 

 punctured, its middle part longitudinally and very minutely striated ; 

 hind angles of the apical segment elongated, acute, not extending so far 

 as the appendages, which are acute : legs piceous ; femora tawny at the

Genus Htpencha, Am. and Serv. 

 Hiat. Nat. lus. Hem., p. 166 (1843): Stal, En. Hem., i, y. 68 (1870j. 

 Head rather pointed : antennae a little longer than in the genus 

 Tessamtoma, with the joints proportionately more slender and not short, 

 stout and incrassate : rostrum not reaching the insertion of the inter- 

 mediate feet : pronotum transverse, the posterior angles prominent, 

 though rather rounded ; the posterior margin slightly rounded and siau- 

 ated, not extending over the base of the scutellnm : sternal ridge ex- 

 tended in a point which becomes lower at the insertion of the inter- 

 mediate feet and advances in the form of a recurved hook, compressed 

 and obtuse, beyond the first pair of feet : scutellnm not reaching the 

 middle of the abdomen, its tip canaliculate or spoon-shaped : abdomen 

 oval, not or only very slightly enlarged on each side : feet as in Tessara- 

 tonia but the internal or posterior spine at the end of the intermediate 

 and last femora is notably more robust than the external or anterior 

 spine : there are apparently no spines at the tip of the first femora : 

 the other characters as in Tessaratoma {Am. and Serv).
