THE CANADIAN ENTOMOLUGIST. 293 



and almost immaculate orange secondaries. On the under surface of 

 both pairs of wings the markings are the same as above, but the ground 

 colour of the wings is much lighter than usual, and is of a lovely lemon 

 yellow ; the abdomen, thorax, head, antennae and legs are the same as in 

 the typical form. 



Of this form, I have seen several examples in various collections, and 

 I believe that it is a sufficient variation to have at least a name of its own. 

 I therefore claim the pleasure of dedicating this pretty form to the 

 memory of my deceased friend, Frederick W. Klages, who was preparing 

 for a second collecting irip to Jamaica, when he was taken ill and died. 



PARTIAL PREPARATORY STAGES OT HEMILEUCA 

 CALIFORNICA, WRIGHT. 



BY G. H. FRENCH, CARBONDALE, ILL. 



The eggs are sub-globular, between that and sub-quadrate, shaped much 

 like Ljina and its allies ; length, .06 inch ; width, .06 inch, by .05 inch in 

 height; smooth, the apex flattened,but the base rounded. Colour, oHve green; 

 those on one side of the twig, red tinted. They were placed round a 

 twig of food plant (willow) with one of the long ways across the twig. 

 They were from California, and where deposited about the last of 

 October. As they hatched the middle of the following April, this would 

 give six months as the duration of this period. 



Young Larva. — Length, .12 inch. Sub-cylindrical, largest at the 

 anterior end. Body black, or, we might say, orange-black ; each joint 

 with six fleshy, cylindrical tubercles, nearly as long as the diameter of 

 the body, from each of which arise two white hairs. Head black ; 

 venter, legs and anal segment orange. Duraiion of this period, 8 days. 



After 1st moult.— \.tr\gi\\, .16 inch. Shaped as before. Uniform 

 brownish-black, the tubercles and all ; hairs grayish- white. Duration of 

 this period, 11 days. 



After 2nd motiit. — Length, .25 inch. Of a uniform black, about the 

 same shade as before ; the two dorsal rows of tubercles orange with 

 black bases, those on the posterior part of the body with the black ex- 

 tending well up on the tubercle, two pale hairs for each tubercle. 



During this period all died. Though I had several thousand of them, 

 I failed to get any past the third moult. They were extremely gregarious 

 in their feeding, huddling together on the food plant, and moving but 

 little.
