1897] ENTOMOLOGICAL NEWS. ?13 



The collector longed for a dozen arms and as many nets, or an 

 abundance of time to sit down and study " Nature at home," 



Epicallia virgiyialis was found here in abundance, and a good 

 series was collected ranging from the light yellow form with most 

 of the secondaries yellow, to specimens with the secondaries 

 black. One species and two varieties are described and listed in 

 our literature on the genus, but the series I have made satisfies 

 me to give but one name {yirginalis). When it is almost im- 

 possible to find two specimens alike as in this case and that of 

 Nemeophila pelrosa, it seems foolish to name all the intergrades. 



Gnophala vermiculata failed to appear in 1893, t)ut was com- 

 mon in 1895, especially in the vicinity of Ogden. Sometimes 

 examples of this species were found on the flowers, but more 

 frequently they were found flying among the foliage of the trees 

 seeming to delight in the sunshine. 



Thecla crysalus abounds on the scrub oaks and resembles the 

 other members of its genus by being hard to capture in perfect 

 condition. Its ability to hide on the leaves of the oak with wings 

 closely folded and only the lines of the under surface showing, 

 furnishes another instance of insect mimicry. 



Probably many collectors have noticed the habit peculiar to 

 the Theclas of moving the wings slowly backward and forward 

 the superiors within the inferiors and at the same time slowly 

 opening and closely both pairs slowly. This is only done when 

 the insect has no cause for alarm, but often aids the patient col- 

 lector by disclosing the bright colors above and helping to locate 

 the fugitive. 



Catocalas are most remarkable for their absence in Utah. In 

 two seasons collecting two specimens of C. aholibah were taken 

 and probably six noted. Usually the few examples of this spe- 

 cies are started near the bottom of canons and the favorite hiding 

 place is among the roots of stunted vegetation. At least twice 

 I have seen specimens on the trestle work of bridges. Synedas 

 are more abundant, and are game to the last breath. One Thecla 

 dumetorum was captured. More Chrysophanus zeros were taken 

 than in 1893. Of the genus Pieris se\&r^\. protodice were noted, 

 and many occidentalism also a few pallida. I do not remember 

 having seen P. rapes in Utah.
