line, is a median and two lateral cream-white spots. Eacli abdomi- 

 nal segment with two similar transverse lines, without the inter- 

 mediate spots; in the anterior line is a dilatation in the middle. In 

 the hinder abdominal segments the hinder of the two cross-lines 

 may be obsolete or represented by a median and a lateral spot. (It 

 agrees very well in general appearance with Bridgham's drawing of 

 the sixth stage, also in the position and color of the tubercles and 

 of the markings, allowing for variation in the latter. 



Egg. — Diameter 0.9 mm. Hemispherical in shape, rather high. 

 The empty shell is thin, glassy, and seen under a triplet to be rather 

 coarsely pitted ; under a |-inch objective the pits are deep, of uneven 

 size, round, but bordered with a raised swollen irregularly poly- 

 gonal margin. The e^^ is much like that of Leucarctia acrsea in 

 shape and ornamentation, the pits being very similar. 



The fully-grown larva of Ecpantheria scribonia (Stoll). 



I found a larva on the alligator pear (?) growing on Mr. McCor- 

 mick's grounds at Lake Worth, March, 1891. It will feed on 

 geranium, and will eat almost anything except orange leaves. 

 Very hardy, standing transportation to the North well. 



Length GO mm. The head is black, becoming cherry-red on the 

 sides and along the front at the base of the labrum. Body deep 

 velvety-black, and with dense fascicles of long dense barbed brown- 

 black hairs. 



When the caterpillar is in motion the sutures on opening are seen 

 to be stained with Indian red or brown madder, forming a conspicu- 

 ous stripe. 



All the eight stages of this species, raised from Florida, have been 

 described at length by Mr. Dyar in the Canadian Entomologist, 

 XXIII, 106. 



The full-fed larva of Ecpantheria permaculata (Pack.). 



I received two larvae, from one of which this moth was reared, 

 from Mr. Th. D. A. Cockerell, of West Cliff, Colorado. He wrote 

 me under date of April 28, 1890, that the caterpillars were collected 

 near Grape Creek, West Cliff, April 28, 1890, and he sent me the 

 brief de.scription, from life, given below. Mr. Cockerell was un- 

 acquainted with the food-plant.
