HEMIPTERA HETEROPTERA. 117 
Genus 4. BLACHIA. 
Corpus brevi-ovatum, convexum, nitens, subpunctatum. Caput sub- 
productum, lobis equilongis. Rostrum sat robustum. Antenne graciles, 
subsetulosz, corporis dimidio longiores; articuli 20 ad 5um longitudine 
subincrescentes. Scutum spinis duabus longis acutis armatum. Scutellum 
latum, corium vix superans. Pedes vix robusti ; femora antica unispinosa ; 
tibiz antice valde dilatate. 
Body short-oval, convex, shining. Head about half the length and 
about one-fifth of the breadth of the thorax; the lobes of equal length. 
Rostrum moderately stout, extending to the hind coxe. Antenne slender, 
very minutely setulose, rather more than half the length of the body; 
joints from the second to the fifth successively but very slightly increasing 
in length. Thorax thinly and largely punctured ; scutum,nearly twice 
broader than long, forming an acute angle on each side of the fore border, 
armed on each side by the fore wing with a long acute diverging spine. 
Scutellum not much contracted hindward, hardly extending beyond the 
corium of the fore wings. Legs hardly stout; fore femora with a spine 
beneath near the tips: fore tibia much dilated. 
This genus seems to connect the Stiretoides and the Asopides, the 
two groups into which the Asopide have been divided. It is most nearly 
allied to Cazira.
