Dynastes, again, 
In Mr. Doll’s article on page 120, I was responsible for the ‘‘Colo- 
rado”, ‘This was error: ‘*Hell’s Canon” 1s in Arizona, some forty miles 
from Prescott. Dr. Horn informs me that the species was probably his 
Granii, though none of his specimens are as large as those caught by 
Mr. Doll. Granta occurs in Arizona, Colorado and New Mexico; and 
with Mr. Doll’s note on its habits they should be found by any collector 
visiting those States, even though they be not fortunate enough to enjoy 
the trip through the canon with the suggestive name. ‘The date, it may 
be added, was September. feels Ss

Short Studies of North American Coleoptera. (No. 2.) By John L. Leconte, 
M. D. Trans. Am. Ent. Soc. XII, pp. 1 to 32. 
This is a collection of such fragmentary manuscripts as were left by Dr. Leconte 
at the time of his death, edited by Dr. Horn. It contains descriptions of a considerable 
number of new species and a revision of four genera of the Hlateridae—Drasterius, 
Megapenthes, Hlater and Agriotes. A considerable amount of new synonomy is con- 
tained in this paper, and the tables are clear and very practical.

A Study of some Genera of Elateridae. By Geo. H. Horn, M.D. Trans. 
Am. Ent. Soc. XII, pp. 33 to 52. 
‘This paper is to an extent supplementary to that preceding, containing synopses 
of Horistonotus, Esthesopus and Ludius, and brief notes on several other genera. Dr. 
Horn’s work is always well done, and this paper is no exception. 
‘These two papers partially fill a great gap in our literature, for the Elaterid genera 
are not only very indefinte, but there is also so much variation in and yet so much 
resemblance between species, that proper determination has been a matter of great 
difficulty, and considerable uncertainty. Melanotus, Limonius and Corymbites are 
still stumbling blocks and we hope that Dr. Horn’s plans provide for an early review 
of those genera.

We have received from Prof. Fernald and Mr. Hy. Edwards that part of the 
‘Standard Natural History’’ devoted to Lepidoptera. According to the plan of 
the work, Prof. Fernald begins with the lowest of the Heterocera and Mr. Edwards 
ends with Papilio, as the highest of the Rhopaloceru. In judging of this work it 
must be remembered—I quote Prof. Fernald—‘‘that 1 was allowed only so many 
pages, and ‘it must be popular”’. Of course, under those circumstances only 
the most cursory survey of the field could be taken. And Entomology seems 
after all to occupy only a secondary or tertiary position in the estimation of the 
publishers; so that besides an enumeration and popular definition of the prin-
