1S8 THE CANADIAN ENTOMOLOGIST, 



classified under the head of variable protective resemblance, that has come 

 under my observation while writing this chapter, is the case of the larvae of 

 Lyceena sp., abundant on the flower-heads of the just-blossoming (May) 

 California buckeye, ALsculus Californicus. The buds of the buckeye are 

 green, or green and rose, or even all rose externally. The quiet slug-like 

 Lycaenid larvae lie longitudinally along the buds and their short stems, 

 and are either green, with faint rosy tinge, especially along the dorsi-meson, 

 or are distinctly rosy all over, depending strictly on the colour-tone of the 

 particular inflorescence serving as a habitat for the larva. The corre- 

 spondence in shade of colour is strikingly exact ; the utter invisibility, or 

 rather indistinguishability, of the larvae is something that needs to be 

 experienced, as my artists, my students, and J have experienced in the 

 last few weeks, to be fairly realized. We have watched the larva: through 

 their whole life, and all the time the safe position along the bud and the 

 immobility are maintained." Several other corrections in the LepidQpUra 

 have been made in the later edition of American Insects. On plate XI 

 the figure of Synchloe sara, which was labelled as the eastern genutia, has 

 been corrected, and also the figure of Neophasia Terlootii, Behr., which 

 was masqueraduig under the name of Archonias lyceas. Will the troubles 

 of NeopJiasia Terlootii ever end ? The figures of Papilio (faunas, Boisd., 

 on page 447, which are figured as rutulus, have not been changed. 



Hesperidie. 

 Pamphila comma juba, Scudder. This large skipper appears to be 

 t|uite common here, and is also well distributed throughout California. 



Thanaos tristis, Boisd. — This species I listed under the name of 

 clitus, Edw. What Wright (Butt. West Coast) figures as tristis (469) is 

 juvenalis, Fabricius, <$ . 



Thorybes Mexicana, Herrich-Schaeffer. — A single specimen of this 

 species was taken in the foothills on April 26. It is somewhat darker than 

 specimens from the Sierra Nevadas. Wright's figure (No. 472) gives a 

 poor representation of the markings of the primaries. 



Hesperia aespita/is, Boisd. — Finding this species flying abundantly 

 about various flowers in the open spots along San Francisquito Creek last 

 summer, I confined a number of females for ova. Of these but a single °. was 

 kind enough to oviposit, and then but a single egg, which proved infertile. 



Egg. — Hemispherical, ribbed longitudinally with numerous raised 

 ridges, between which are finer cross-veinlets. Height and diameter about 

 the same. Colour when first laid pale greenish, changing to light lemon- 

 yellow. Diam. 5 mm.
