are any that I have." (This was in direct reply to my question, suggested 

 by Dr. Holland, who was confident they had been greased and cleaned.) 

 " I do not notice this shiny surface especially in the males ; they are all 

 fulvous, and none show melanism. All the females tend to obscuration, 

 and more than half are about as melanic as those sent you, one or two 

 perhaps a little daricer. Some few are clear enough for the fixed lines to 

 show. This form does not at all frequent the same localities as Chariclea, 

 which only occurs below timber, so far as I know." 



Alberta is wholly unlike any member of the group known to me. It 

 does not at all agree with Char idea, var. obscurata McLachlan. 



In the delicacy of its markings the male is nearer Helejia than 

 Chariclea, but these are interrupted and reduced. Helena is an alpine 

 species, and found above timber line. But it retains at every elevation 

 which it frequents the same features. The examples under view are 

 larger than any Helena, and equal the largest Chariclea. 



NOTES ON SIGALPHUS CURCULIONIS AND SIGALPHUS 



CANADENSIS. 



BY C. P. GILLETTE, AMES, IOWA. 



I reared from Conotrachelus nenuphar last summer a number of 

 parasites, which were determined for me by Dr. Riley as Sigalphus cur- 

 culionis Fitch, and S. curculionis, var. rufus. Full descriptions of both 

 of these may be found on page 27 of Riley's Third Missouri Report, and 

 upon page 67 of the Supplement to the Missouri Reports. 



The variety rufus appeared much more abundant than curculiofiis in 

 my breeding cages the past summer. These two forms differ so much 

 from one another, and in some respects, especially in the number of joints 

 of the antennfe, from Riley's descriptions, that I have made the following 

 notes upon them : — 



Three females of the dark form, bred by myself, and two males loaned 

 me by Prof. Osborn, have the ocelli in every case, not touching, but dis- 

 tinctly separated. The two males have respectively 29 and 30 joints in 

 the antennae. Two of the females have 29 joints each, and one 28 joints 

 in the antennae. The largest female measures just .14, and the maleg
