be readily seen, the groove for the reception of the bodies of the 

 specimens forms the center ; i shows the gimlet hole through 

 which the pin passes; 2 is end of strip of wood to be placed at 

 the bottom, as can be better seen in Fig. Ill, i. 



Fig. II represents the block with bottom open, showing the 

 anatomy as it were. A groove a bit wider than the top one is 

 cut directly underneath it, 3. Another groove yet wider than 

 the last is cut as shown at 4; 2 are very thin pieces of cork about 

 T J g- inch, thick glued over the gimlet holes. 



Fig. Ill shows the block with bottom closed, that is to say 

 with strip of wood, i, placed in position. The block should be 

 made of soft wood, such as poplar or basswood. By drawing 

 parallel lines about ^ inch, apart across the block, as shown in 

 Fig. I, the wings can be set even with greater exactness.

LIFE-HISTORY OF PAMPHILA ETHLIUS Cr. 



By HARRISON G. DYAR. 



Mrs. Slosson called my attention to some Hesperid larvae that 

 were eating the leaves of Canna planted in the grounds of the 

 Hotel Royal Palm at Miami, Fla. They were numerous, and at 

 some points had considerably injured the appearance of the 

 plants. We concluded that they must be P. ethlius, which 

 proved to be the case. Mrs. Slosson asked me to describe them, 

 and, with the help of Dr. Prime, I found all the stages, thus 

 avoiding the necessity of slow breeding. The larva is the most 

 transparent that I have seen. 



Egg. Singly, scattered on either side of the leaf; almost per- 

 fectly hemispherical, like a Notodontian; white, opaque, not 

 shining, with a delicate under tint of green, which gives place 

 later to reddish. Surface minutely and densely white granular 

 as in nadata; micropyle punctiform, depressed. Diameter i mm. ; 

 height .6 mm. 



Stage I. Forms two incisions in the edge of the leaf and 

 bends over the included part by threads. Head rounded conic, 

 black-brown, shining, not notched; width .55 mm. Joint 2 rather 

 small, with a narrow, black, cervical shield. All else whitish 

 translucent, green from the food; spiracle of joint 12 large and 

 conspicuous, whitish. Skin dull, not shining; setae not seen with
