74 AMERICAN HEMIPTERA. 



latero-anterior margins irregularly eroded, with about four filimentous 

 teeth, those at the anterior angles reaching to the front of the eyes; 

 callousities and an indistinct sublateral and median vitta smooth or 

 somewhat calloused ; the surface posteriorly with irregular transverse 

 rugae; the nodular humeri narrowly margined. Scutellum uneven and 

 swollen at base ; the produced apex with a thickened submargin and 

 short median carina. Connexivum broad, deeply notched, the base of 

 the segments swollen. Length 12 mm., width across the abdomen 8 

 mm. 



Color obscure, fulvo-testaceous tinged with ferruginous on the base 

 of the scutellum and the humeral angles. Whole surface punctured 

 with fuscous ; these punctures becoming black in places, especially on 

 the middle of the pronotum anteriorly, scutellum and costal area of the 

 corium. On the lower surface there is a line on either side of the head 

 beneath the base of the antennae, a dot before the eye, a curved line 

 below the expanded margin of the pronotum, a few dots and lines on 

 the pleural pieces and the incisures at the margins, black. Sides of 

 the pleurae and venter strongly irregularly punctured with black, the 

 disk smooth. An anriulus before the apex of the femora, two on the 

 tibiae and a point on the knees fuscous or black ; middle of the 

 antennal joints dusky. 



Described from one female taken in Florida and kindly 

 given me by Mr. J. H. de la Torre Bueno. This insect has 

 much the aspect of a small Brochymena, but in its generic 

 characters it agrees entirely with Pharnus except for the pro- 

 duced contiguous cheeks, fimbriate margins of the pronotum 

 and produced nodular humeri. 



Rhyparochromus aiigiistatus n. sp. 



Form oblong, parallel-sided ; black, with the legs ferruginous and 

 the costal and sutural margins of the corium whitish, forming a dis- 

 tinct M when the elytra are closed. Length 5 mm. 



Head black, minutely aciculate ; vertex moderately convex, nearly- 

 square ; cheeks and tylus produced in a blunt triangle, the front of the 

 head less deflexed than in the Europen prcetextatus . Antennae flavo- 

 testaceous ; first joint surpassing the tylus by one-third of its length ; 

 second nearly twioe the length of the first, blackish at tip ; third 

 shorter than the second, piceous becoming pale at base ; fourth scarcely 

 longer than the third, blackish. Rostrum castaneous, attaining the 

 intermedate coxae ; second joint obviously but not greatly longer than 

 the third. Pronotum subquadrate, minutely rugulose ; anterior angles 

 moderately rounded ; sides distinctly and continuously but slenderly 

 carinated, feebly sinuated ; anterior lobe slightly convex, hardly twice 

 the length of the posterior; the latter of a velvety piceous-black, con-
