ENTOMOLOGICAL SECTION. Ill 



Mr. Calvert detailed the results of recent studies of Neuroptera, 

 and reported the following captures in Maine by Miss M. Wadsworth, 

 during the summer of 1888, not heretofore recorded from that region : 

 Argla violacea Hag., very abundant, IscJmura Ramhurii Selys, rare, 

 Anax Junius Drury, Oomphaesehna furciUata Say, one S , Aeschna 

 Janata Say, one % , Gomphns spinosus Selys, one 9 , G. exilis 

 Selys, Cordulegaster maculatus Say, very common, Epitheca Wahhii 

 Scud., one % , Cordulia semiaquea Burm., common, Llbellvla quad- 

 rimaculata Linn., Leucorhinia proxima Hagen mss. 



Mr. Calvert also desired to record the capture of a S of the cos- 

 mopolitan Pantala Jiavescens Fab. at Mt. Pulaski, Logan County, 

 111. The most Northern localities heretofore reported are Maryland 

 and St. Louis. Lestes enrina Say has been taken by Mr. G. D. W. 

 Williamson at Dobb's Ferry, N. Y., hitherto reported from Massa- 

 chusetts and Illinois. 



Dr. Horn illustrated the mode and extent of variation which he 

 had found in .some Halticini, notably in Systena, in one of the spe- 

 cies the sculpture may be quite coarse, varying to entirely smooth, 

 and the color, from piceous with vittate elytra to entirely yellowish 

 white. 



Mr. Wells gave an interesting account of a visit to Prof French 

 at Carbondale, Illinois, where he examined some Lepidoptera of in- 

 terest, notably Catoeala ulalume Strk., concerning which he made the 

 following remarks : " I have always thought from reading descrip- 

 tions only, that this species would prove to be a variety of retecta. 

 Professor Grote, with some hesitation, admits it into his Check List. 

 He expresses his opinion regarding this Catoeala as follows : ' The 

 description of dejecta is so vague that I have not included the name. 

 Ulahime, equally poorly described, I have included on the strenoth 

 of two typical specimens in my collection, purchased as such from 

 Mr. Peck, and which appear to me distinct,' etc. Prof French con- 

 siders it a distinct species, and I incline to the same opinion. Upon 

 comparing ulalume with retecta, seven or eight examples of which I 

 have in my cabinet, I find the subreniform spot in the former closed, 

 while in the latter it is open. The forewings in xdalume have a de- 

 cided bluish tinge, the dark markings, with some exceptions, very 

 indistinct, or altogether wanting, the usual patch outside the t. a. 

 line made conspicuous by its bluish white color, in fact the tout en- 

 semble of the insect impresses the eye as distinct. There seems to 

 be some analogies between this Catoeala and diminutive specimens
