62 THE CANADIAN ENTOMOLOGIST 



After Third Moult. — Length .65 inch. At nine days from this meult 

 was full grown. 



Mature Larva. — Length i.i inch • stout ; thickest at 4 and 5, taper- 

 ing rapidly to 13, and ending in two short sub conical tails ; colour buff 

 the dorsal area of a yellow tint, the sides reddish ; the under side a green 

 tint up to the red-buff; feet and legs same ; a brown mid-dorsal stripe ; on 

 side the band a shade darker than the ground ; the basal ridge lighter, 

 or yellowish ; body thickly covered with rather stiff, long hairs ; head 

 small, sub-globose, a little depressed at top ; colour greenish-buff, with 

 many buff tubercles and hairs both long and short. (Fig. i.) 



Soon after, the colours became paler, the bands faded, and the larva 

 was lethargic, eating nothing, but lying at the top of the sod curved like a 

 figure 6. At 18 days from third moult pupated in the grass, unattached. 



Chrysalis. — Length .54 inch ; breadth at mesonotum.18 inch, across 

 abdomen . 24 inch ; abdomen remarkably stout (one-third broader than 

 the anterior segments), conical, but irregularly so, the ventral side and the 

 whole body up to thoracic segments being greatly swollen, while on 

 dorsum the curve is slight, and rises no higher than does the mesonotum ; 

 this last is very low, rounded both ways ; the head case short, rounded at 

 end, rounded transversely and at the Corners ; at each shoulder, over the 

 thoracic spiracle, a black-brown, corrugated shell-like process standing 

 out obliquely and quite prominent, in the middle sometimes a little separ- 

 ated from the surface of the body ; cremaster short, bluntly pointed, on 

 dorsal side having same curve with abdomen, on ventral side excavated, 

 with the edges thickened, horse-shoe shaped, and having at the end a 

 brush of short, stiff bristles, straight, not the least hooked. (Figs. 3, 4, 5 

 to 8.) Duration of this stage 14 days. 



This pupa is very like that of Eudamus Tityrus and Lycidas ; the 

 same dorsal and ventral outlines, same slope from mesonotum to top of 

 head, same form of head case ; and the thoracic spiracle protector (Fig. 8), 

 as Mr. Scudder calls it, is similar in both ; in Galathea this process is more 

 curved and shell-like, and a little more projected from the surface, but 

 they are essentially of same character. 



Galathea flies in Europe and Algeria, according to Kirby. It is 

 prettily checkered in black and white, has a slender body, and large wings 

 in proportion, as in most of the family. It has no near ally in North
