Type (from Onaga, Ks. , July 5, 1898; Milwaukee, Wis., 

 male and female). — No. 12188. U. S. National Museum. 



This species has a great similarity to A. exiguus but is 

 distinct from it by the more robust form and in having the third 

 antennal joint for one third of its length at base black. It seems 

 to be the western representative of the genus and has been 

 found as far north as the state of Minnesota. 



ATHEAS 

 AUSTRORIPARIUS 



Atheas austroriparius n. sp. 



Body elongate-oval, depressed, black. Later- 

 al margins of the pronotum and elytra hyaline, 

 yellowish-white. Head hardly broader than long, 

 blackish; antenniferous tubercles prominent, dis- 

 tinctly diverging at apex. Antennae slender, as 

 long as from the apex of the head to the tip of the 

 triangular portion of the pronotum. First two 

 joints equally stout and black, the terminal a little 

 less, blackish, third thin, yellowish, with a short 

 black band at base. Pronotum very feebly convex, 

 narrowing towards the front, closely and deeply 

 punctured, lateral margins straight, narrow post- 

 eriorly, thence widening anteriorly; pronotal cari- 

 nas feeble, somewhat indistinct at the middle, the 

 abbreviated outer ones parallel to the median 

 carina; triangular portion of the pronotum rather 

 short, tip obtusely rounded, yellowish. 



Elytra somewhat less elongate, widest at the middle and gradually 

 rounding towards apex; discoidal area very long, extending nearly to the 

 tip of the abdomen, with four rows of small areoles at widest part, the outer 

 and inner longitudinal nervures black; subcostal area wider than the costal 

 with three rows of small areoles, the nervures light brown; costal area with 

 one row of medium sized areoles and some smaller cells near the margin; 

 sutural area with larger areoles near apex and much smaller and irregular 

 ones at the inner side, nervures fuscous or brownish. Rostral laminae at 

 mesosternum parallel, yellowish-white. Legs yellowish-brown, tarsal joints 

 infuscated. This species has also a brachypterous form like the preceding. 

 It differs from that in having a somewhat larger and broader body and the 

 elytra not longer than the abdomen. 



Length 2.6 m. m.; width 1 m.m. 



Described from three specimens, females, two of them 

 brachypterous. Columbus, Tex., June 16 (Coll. C. V. Riley);
