XXxii, '21] ENTOMOLOGICAL NFAYS 127 



In a work of this magnitude it is inevitable that there should be 

 mistakes, but these arc of a minor character, and gradually will be cor- 

 rected. Anyone who, through experience, appreciates the enormous 

 grind that this bibliographic work has entailed cannot but congratulate 

 Mr. Leng'on having successfully driven through his labor to completion. 

 The work will undoubtedly give a new impetus to the study of beetles 

 in our country, and we hope that before many years the interest in 

 this dominant order of insects will be such that it will be financially 

 possible to publish a catalogue with references to original and later 

 descriptions after each species in the manner of other catalogues of 

 insects. The publisher, Mr. Sherman, is also a Colcopterist, and it is 

 largely due to his unremitting energy that the catalogue is in print.

CHECK LIST OF THE INSECTS OF CONNECTICUT. By WILTOX EVERETT 

 BRITTON, Ph.D., State Entomologist and Entomologist of the Agricul- 

 tural Experiment Station, New Haven, Conn. Hartford. Printed for 

 the State Geological and Natural History Survey. 1920. This work of 

 397 pages should accomplish what its author had in mind when he pre- 

 pared it, to stimulate an interest in the study of insects in the State, in 

 relation to man in the broadest sense, but with a special interest in 

 economy. 



"A work entitled a Guide to the Insects of Connecticut, containing 

 keys to orders, families, genera, and species and including much infor- 

 mation about life-histories, habits, distribution, etc., is already in 

 progress." 



The Check List will be very useful in the preparation of parts of the 

 Guide to be issued, as additional species and additional facts are the 

 natural result of such a list ; in other words, interest is stimulated. 

 Doubtless errors have crept into the list, but think of the joy that will 

 accrue to the person finding and reporting them. 



Dr. Britton is to be congratulated on the publication of such a useful 

 list and we would like to see every State in the Union do likewise.

LEPIHOPTERA OF THE CONGO, Being a Systematic List of the Butterflies 

 and Moths Collected by The American Museum of Natural History 

 Congo Expedition, Together with Descriptions of Some Hitherto L T nde- 

 scribed Species. By W. J. HOLLAND. Bulletin of the American of 

 Natural History, 1920,' XL-Ill, pp. 109-369. This paper is well illus- 

 trated with excellent colored half-tones of numerous species and some 

 text figures. Dr. Holland has been a student of the African fauna for 

 many years and is well qualified to prepare such a work and the present 

 contribution is one of real merit and value. The collection contained 

 nearly n'no thousand specimens and upwards oJ icven hundred and 

 twenty fivi pecies. 1 1 . SKINNER.
