form, larger size, deeply impressed elytral stride and convex intervals. 

 The specimen described is a female and has the outer antennal joints 

 relatively wider than those of the females of gracilis and cvancscois. 



The two species in our list, gracilis and cyancsccns, seems to be 

 rare, at least in collections, and have been considered by some to be 

 possibly one variable species. I have four females of gracilis and a 

 number of cyancsccns of both sexes. They are very close and it is 

 possible that specimens of gracilis may occur with black legs ; how- 

 ever, there is a difference in the relative length of the anteimal joints, 

 which are relatively shorter and the outer ones wider in gracilis. The 

 form of gracilis seems to be also slightly shorter and a little more 

 convex than cyancsccns. 



I have another form which looks quite distinct on account of color 

 and more elongate, parallel form which seems to be entitled to a name. 



Stenochidus cyanescens var. carbonarius, new variety. 



Form of cyanescens, but more elongate and parallel ; upper surface black, 

 legs and antennae brown or piceous ; thorax less densely punctate than in 

 cyanescens. Length 8.25—9 mm. 



Tulare County, California. (O. Dietz.) 



There seems to be also a slight difference in the form of antennal 

 and tarsal joints, but the few specimens I have are not quite perfect. 



BLATCHLEY'S BEETLES OF INDIANA/ 



This is a volume of 1.3H6 pages with 590 figures in which 3.555 

 species of beetles occurring or supposed to occur in Indiana are de- 

 scribed, 79 as new species. No such comprehensive work has here- 

 tofore appeared on American beetles and the book will be most useful 

 to students of Colcoptera. 



The book starts with a brief treatise on the external anatomy of 

 beetles in which the technical terms to be used are explained by text 

 and figures. A copy of the classification of families by Leconte and 

 Horn follows, and then each family is taken up in turiL The treat- 

 ment includes a brief account of the habits, the division into tribes,
