the sides into obtuse ears, and slightly excavated between 

 them ; the thorax has a sharp raedio-dorsal keel ; the abdo- 

 men is dorsally somewhat verrucose, having four longitudinal 

 dorsal series of extremely depressed and scarcely perceptible 

 warts ; colour almost white, sometimes slightly tinged with 

 green, and ornamented with numerous black markings, of 

 which the undermentioned are the most conspicuous — a nar- 

 row dorsal line on the thorax, divided just behind the head, 

 and again united ; two dorsal stripes commencing very near 

 the back of the head, passing on each side of the thoracic 

 dorsal line, then dilating and broken up into subquadrate 

 and rather paler blotches ; on each side exterior to these is 

 another somewhat similar marking, commencing on the 

 thorax as a stripe, but interrupted and vague towards the 

 anal extremity ; and again, exterior to this is a broad black 

 linear patch adjoining the wing-cases; the wing-cases are 

 dashed with black longitudinally ; the cases of the antennae 

 are.most delicately marked with black, each joint having two 

 round black dots ; the cases of the middle and hind legs are 

 almost entirely black. The last skin of the larva is not shed, 

 but, being gradually pushed downwards by a wriggling 

 movement of the pupa during its metamorphosis, encom- 

 passes the anal segment only, and remains in this position 

 even after the butterfly has made its escape. The butterfly 

 is on the wing during the whole of July : I have never seen 

 the slightest indication of a second brood. — Edward Newman. 

 Life-history o/Lyccena bostica. — The last-disclosed females 

 of this species lay their eggs on the twigs of Colutea arbores- 

 cens (bladder senna), but, like those of several, and perhaps 

 all, the British species of Thecla, they do not hatch until the 

 following summer, at which season the young pods of the 

 Colutea are suflSciently advanced to serve as its food : the 

 young larva is almost black, and at first only destroys the 

 scarcely-formed pods ; subsequently it enters the pods 

 through a nearly circular aperture, and devours the seeds ; 

 before attaining its full size it migrates frequently from pod 

 to pod, only devouring the seeds in the interior : it rests on 

 the pods or on the twigs in a straight position, its shape 

 scarcely allowing of any other. Head very small, scarcely 

 half so wide as the Snd segment, into which it is susceptible 

 of being withdrawn, and thus entirely concealed : body
