ON THE LIFE-HISTORIES AND IMMATURE STAGES OF 

 THREE EUMLOPINI. CORRECTIVE NOTE. 



BY STEPHEN ALFRED FORBES, NORMAL. ILLLN'OIS. 



I regret to li;ne to report a mistaken 

 identification of tlie species of Scchr 

 doiita mentioned in m}' paper "On the 

 life-histories and immatnre stages of 

 three cnmolpiiii (Psyche, Jan. -Feb. 

 1SS4, V, 4, p. 123-130, pi. I). 



Wiien the imagos appeared in onr 

 breeding cages last June (see Psyche, 

 V. 4, p. 139), I sent a pair of them to 

 Dr. J. L. Leconte. with a request that 

 he woulil take the trouble to determine 

 them for me ; and mentioned at the same 

 time the economic relations of the 

 species. 



In his reply, dated June 34, 1SS3, 

 from Alexandria Bay, N. Y.. he says: 



"I have examined carefully the speci- 

 mens of Gniphops \_Scclodo>ita'\. which 

 were safely received just after 1113- ar- 

 rival here. I find that they are witliout 

 doubt G. pitbcsccns; that species difi'ers 

 from allied ones G. ctirtipcnnis and 

 G. marcassita. bv the more elongate 

 form and by the punctuation being ru- 

 gose only at the sides." 



With this decision I. of course, rest- 



ed content, until this month, when the 

 reception of specimens of Scclodonta 

 collected from evening primrose (yOoio- 

 thcra biennis)^ in southern Illinois, in 

 the vicinity of strawberry fields, led to 

 a review of this determination. It was 

 soon evident that these primrose speci- 

 mens were of a different species from 

 those breeding in strawberries, and had 

 also a different life-history, since they 

 were taken /// copula., in April, at which 

 time the strawberry species was abun- 

 dant in the earth, in the larval condition, 

 not to appear as adult until June. 



As the primrose specimens agreed 

 closely with all accessible descriptions 

 of 5'. pubcscens, I enclosed to Dr. G. 

 H. Horn a specimen of this lot, togeth- 

 er with one from the lot bred from 

 strawberry root-worms last June, with 

 a statement of Dr. Leconte's previous 

 identification of the latter as S. piibes- 

 ccns. 



In his replj-, received this morning. 

 Dr. Horn determines the jjrimrose spec- 

 imen as 5'. puhescciis^ and that from the
