much larger than those of prothorax. Beneath the outer apical 

 angles of anterior tibiae are rounded and spinulose. First 

 ventral segment of male with a circular fovea on posterior half. 

 Length 2 mm. Width 1 mm. Key West, Fla. Bred from 

 Fomes marmoratiis. Berk., C. G. Lloyd, And three specimens 

 ftom Round Mountain, Texas, which do not differ from the 

 Florida specimens, received from H. W. Wenzel, This species 

 is the broadest for its length of any I have seen. It deviates 

 somewhat in generic characters, but they are hardly sufficient 

 for another genus. 



Ennearthron oregonus, n. sp. 



Elongate, cylindrical, slender in form, shining. Head and 

 prothorax red; elytra piceo castaneous in color. Male — 

 Head with epistoma reflexed and produced into a rather long, 

 broad, lamellar process, slightly emarginate at tip. Front with 

 a strong transverse shining concavity. Prothorax about as 

 long as wide. Alutaceous finely and sparsely punctate. Apex 

 produced into a very thin, upturned, gradually formed process, 

 strongly emarginate at tip. Elytra about two and one-half 

 times as long as wide and of same width as thorax. Punctuation 

 slightly rugose and coarser and more dense than that ol pro- 

 thorax. Beneath the apex of front tibiae are roimded and 

 spinulose at apex externally. The first ventral has a small, 

 round fovea on posterior half at middle. Length 1-50 mm. 

 Corvallis, Oregon. Mr. Moznette. Allied to Convergens Csy. 

 a large series may show the two to be identical. Two males. 



Ennearthron color adense, n. sp. 



Elongate, dark piceous, shining. Head, legs and antennae 

 pale, and the latter very elongate and 9-jointed. The third 

 joint as long as the fourth, fifth and sixth together. Allied to 

 thoracicorne, which has the third antennal joint only equal to 

 the next two. Elytra twice as long as prothorax and slightly 

 wider; closely and finely punctate. Prothorax alutaceus, 

 deeply and evenly punctured, the punctures being smaller 

 than those of elytra. Only males were seen. The epistoma
