Sytiopsis of the Coleopterous Faniili/ Cixitlae (Cioidae) '•27 



Octotennnis, Mellie 



Casey gives a good generic diagnosis in Journal New York 

 Ent. Soc, vol. vi, Xo. '■2, p. 91. and describes two species, 

 Octotemnua denudatits and O. laeri.s. The former from the west 

 coast and the latter from the Eastern L nited States. I have 

 seen the types. In a large series of specimens from many 

 localities the characters given to separate them seem to run 

 together so that I can not find any of specific value to distinguish 

 the two. In both forms the prothorax is alutaceous, with 

 ])unctures about the same. Some specimens of both are more 

 elongate and less oval. The size averages the same. The 

 darker ones are the more mature ones. The species is a glabrous 

 insect, finely punctured, averaging about 1.75 mm. in length. 

 The males are without sexual marks on either epistoma or 

 prothoracic apex. Color from pale to dark. I have seen 

 .specimens from Penn.sylvania, Ohio, Alabama, Iowa, Kansas, 

 Oregon, Washington and California. At Cincinnati. Oliio, 

 they live in various species of fungi and are very aliundant. 

 Those from Oregon were bred from Coriolus versicolor and 

 Poh/siictu.s-.
