refused to eat, and thus suicided. The remaining eggs I sent to 

 Mr. W. H. Edwards, but they failed to hatch. The female pano- 

 quin differs from the other sex in being larger, several shades 

 darker in color, and in having the maculations on the superior 

 wings much more sharply defined and brighter in color. There 

 is a prominent light colored streak on the inferiors nearly one- 

 quarter inch in length, which is either wanting or only indicated 

 in the male. 



A colony of full grown Ju7i07iia ccenia larvae were found feeding 

 on Gerardia temdfolium, which, as far as I know, is a new food- 

 plant for the species. 



NOTES ON COLEOPTERA. 



BY GEO. H. HORN, M. D. 



From the remarks of Mr. Fauvel (Revue Ent. 1889, p. 142) it 

 is evident that two species of Cryptohypnus have been confounded 

 under one name by many of the Coleopterists of Europe, notably 

 by Dr. Candeze, whose work has been accepted as authority on 

 the family Elaterid^ for many years. It is pardonable in 

 students on this side of the Atlantic if they are found guilty of 

 an error due to, or rather copied from, those who should be final 

 authority on the species of the fauna around their own homes. 



C. pulchellns Linn., exiguus Rand., guttatulus Mels. 



The above line appears in Dr. Hamilton's paper on the Cole- 

 optera of the sub-arctic regions common to both hemispheres. 



From the remarks of Fauvel two species have been confounded 

 under pulchellus, which have a great superficial similarity ; these 

 are : 



C. pulchellus Linn. — Thorax with posterior angles sinuate, di- 

 vergent and acute at the apex, the striae of the elytra obsolete at 

 the tip. 



C. sabidicola Boh. — Thorax with posterior angles arcuate, 

 rather incurved, obtuse at apex, elytra deeply striate, the inter- 

 vals subcostiform. 



Any one who will read the descriptions of Randall and Mels- 

 heimer, which are remarkably good, will see that we have in our 

 iawnz. pulchellus as described by Fauvel.
