Pupae of Dorcus parallelus, Say. 



About the middle of August, I found in the roots of Maple and Bass 

 trees, several pupae and newly developed imagines of Dorcus parallel- 

 us, Say. 



The pupae present a very remarkable and interesting sexual differ- 

 ence, those of the $ having besides the naturally much larger, plump cov- 

 er of the mandibles, between the anal fork a spiral prolongation complete- 

 ly filling with its spirals the space between the anal fork. 



The prolongation begins at the anus, goes straight to the 

 end of the anal fork, and then turns backwards forming three spirals 

 the terminal part of which, the end of the third spiral, being at the left 

 side of the last abdominal segment. 



In newly developed imagines the cover of this prolongation contains 

 a filiform thin spiral about 30 mm. long, rather longer than the whole in- 

 sect. After a few hours it is retracted into the abdomen, I do not know 

 the use of this part. 



I have in Alcohol two larvae of tf, two of 9. on e imago newly de- 

 veloped, and dissected two old species. F. G. Schaupp. 



NEW PUBLICATIONS. 

 Geo. II. Horn, M. D. 



Trans. Am. Ent. Soc. IX. pp. gi-ip6. with 8 plates. 



On the genera of Carabidse with special reference to the Fauna of Boreal 



America.— An entirely new arrangement of the Carabidre based on an autopsy, the au- 

 thor having dissected and with his well-known accuracy and skill, carefully examined 

 all the characters on which the genera were based. In many instances the old arrange - 

 ment is greatly modified and altered. The first plate gives the underside of each of the 

 Adephagous families, the 2nd some of the rarer and more interesting species as Misco- 

 dera, Onota, Eucrerus, Evolenes etc., and the other six anatomical details, mostly mouth- 

 parts (about 300 figures!) The work may create an ill feeling among some authors but 

 what Dr. Horn did, was done from the love of truth and science. 



Note on larva and pupa of Cryptorhynchus 

 parochus, Say- 



Several larvae and pupse of Cryptorhynchus parochus, Say, were found 

 last season, Aug. 10th under the bark of a butternut-tree. The greater 

 part of pupa? were looking through the bark by half their length and mov- 

 ing lively in the sunlight. Duration of pupa state 14 to 16 days.
