THE ENTOMOLOGIST. 221 



shaped like a woodlouse, the dorsal area convex, the ventral 

 area flat, the incisions of the segments very clearly marked. 

 Colour of the head black : dorsal area of the body olive- 

 green, reddish brown or bright green ; there is a dark and 

 moderately wide medio-dorsal stripe, perfectly continuous, 

 from immediately behind the head to the anal extremity, and 

 also a white lateral stripe below the spiracles, which are yel- 

 low ; iunnediately above each spiracle, with the exception of 

 the first and last, there originates a rather short line, which 

 passes obliquely forwards and upwards towards the medio- 

 dorsal stripe, but never unites with it ; these oblique lines 

 are longitudinally double throughout, the upper part being 

 darker and the lower paler than the ground colour; the 

 claspers are concolorous with the ventral area ; the legs 

 brown. When full-fed this larva never remains within the 

 bladder on the seeds of which it has fed, but (generally in the 

 month of September) it escapes from the pod which had last 

 served as its dwelling-place, and either descends among the 

 dried leaves or attaches itself to a branch of the shrub, and 

 in five or six days assumes the pupa state. The pupa is 

 attached by a girth round the middle to the stem of the 

 Colutea ; it is obese, and rounded at both extremities ; its 

 colour testaceous yellow or dull red, adorned with brown 

 dots, which are particularly numerous about the crown of the 

 head ; there is also a continuous dark line in front, extend- 

 ing from the thorax to the anal segment ; the spiracles are 

 black and plainly discernible with the naked eye. It remains 

 in the pupa state a fortnight, the butterfly appearing on the 

 wing about the middle of September, and continuing to fly 

 throughout October. The larva is infested by a minute 

 Ichneumon (Microgaster glomeratus), fourteen or fifteen of 

 which frequently feed on a single larva, and these, escaping 

 through the skin of the butterfly larva, spin a cluster of little 

 yellow cocoons, attaching them to the stalks or leaves of the 

 food-plant. Lycaena boetica having twice occurred on our 

 coast near Brighton, and having thus established its claim to 

 be considered British, 1 have extracted the foregoing particu- 

 lars from M. Milliere's beautiful work, kiudly lent me by Mr. 

 Doubleday, from whom I obtain the additional information 

 that the larva is also found feeding in the pods of the field 

 pea. — Edward Newman.
