 gined with testaceous ; ocelli brown or black. AntenncB testaceous, 2nd joint 

 black, shining ; setae brown or reddish-brown. 



Thorax : pronotum black or fuscous black, finely crenulated, with a narrow, slightly 

 curved, longitudinal line on either side of the centre : near the anterior margin 

 two large black spots almost exterior to those on the crown ; lateral and posterior 

 margins testaceous, the colour in the former extending for a little way upon the 

 disc in an angular shape. Scutellum testaceous, with a triangular spot at each 

 basal angle, and a somewhat square patch in the middle, extending from the 

 base to the transverse channel ; or black, with the sides, between the transverse 

 channel and the apex, narrowly yellowish-white. Tllytra pale testaceous. 

 Clavus — basal half of the central nerve white, on either side broadly margined 

 with black, that next the suture shortest and widest ; suture, at the base, pale. 

 Corium—stnteriov marginal nerve interiorly narrowly black, 1st longitudinal 

 nerve, for a short distance from the bifurcation, pale ; inner longitudinal nerve, 

 from the base to in a line with the bifurcation of the 1st nerve, pale. 3Iem- 

 hrane — nerves black. Sternum black. Prostermim — exterior and posterior 

 margins very narrowly testaceous. Legs black ; thighs of all the pairs at the 

 apex, and along the upper margin, more or less broadly testaceous. Tibice — 

 1st and 2nd pairs, base frequently, a somewhat broad band in the middle, 

 and the apex narrowly testaceous ; 3rd testaceous, more or less broadly black

 rupted. Tarsi brownish-yellow or fuscous ; 3rd Joint and claws black. 



Abdomen black ; external processes yellowish or yellowish-white. 



$ . Much paler than the S , aud with the nerves of the elytra and membrane lesg 

 broadly black ; frequently the nerves are brownish, and the face is never black 

 as in the S • Length, 1 — 1^ line. 



Slightly shorter and stouter than A. pimcticeps, and in the ^ of 

 a decidedly blacker hue. Its black face, sternum, abdomen, and legs 

 will at once lead to its identity. 



A very common species everywhere, both on the sea coast and 

 inland, from July to September.

 Atliysanus hracJiypterus, Boh., Handl., 20, J* (1S47).

 151, 5 ; J. Sahib., Not. Penn., part xii, 154, 3. 



Somewhat stout, testaceous-white. Croion broader and wider than in 

 the two foregoing species. Elytra scarcely covering half the 

 abdomen, rounded posteriorly. 



Head : croion with a narrow, black, central line, carried down the face to a little 

 beyond the ocelli, where it is widest, and, when viewed from the front, appears 

 like an isosceles triangle ; on each side of the central hue, and nearer to it than 

 the inner margin of the eyes, a large, round, black spot. Face with a black, 

 oblique streak, extending from the ocelli to a little beyond the base of the
