the ones on knobs of anal segment slightly longest. Spiracles small, oval, 

 white with thin, shiny black margins. Colour of larva dark bluish green, 

 light greyish green on ventrum ; true legs glassy green ; prolegs yellowish 

 with wedge-shaped, lobed feet. L : 27mm ; B : 4 mm. 



Pupa. — Is of the agulated type of Appias {vide PI. 1, fig. ). Head short, 

 as broad as segment 2 by which it is nearly completely hidden ; produced 

 into a long snout in front, which snout is cylindrical, rounded at end, 

 slightly down-curved and rugose as to surface ; eyes slightly prominent. 

 Segment 2 flat on dorsum, keeled in dorsal line and produced into two 

 sharp points, one subdorsal, on each side, which lie separated by a rounded 

 sinus, close together over the base of the snout. Thorax broader than 

 segment 2, the wings (lateral outline of pupa) run back from the shoulders 

 parallel to longitudinal axis of pupa and to each other as far as segment 

 6 ; the dorsal portion of thorax slopes up from the wings to a dorsal carina 

 occupying its whole length, the lateral outline of which is triangular, the 

 somewhat thickened apex being the highest part of pupa ; the hinder margin 

 is straight on each side between dorsal line and wing, the two halves 

 meeting in a wide angle, the half on each side meeting the wing in a 

 rounded right angle. Segment 4 dorsally somewhat convex, short, also 

 slightly earinated in dorsal line. Segment 5 is dorsally flat, short. Seg- 

 ment 6 and the anterior half of segment 7 are dorsally quite flat and are 

 produced thinly laterally out over the wings into a ledge ; this ledge is 

 continued thinly above spiracles to the cremaster along abdomen ; this flat 

 part is bordered posteriorly by a slight, straight ridge across pupa at centre 

 of segment 7, the ridge being produced out at each end into a strong, re- 

 curved, angular tooth, the tooth being flattened above and below, its front 

 margin formed by the anterior margin of segment 7 ; the lateral ledge of 

 segment 6 is also toothed slightly but to a far less degree at the anterior 

 corners ; and there is small, rounded tooth besides, between these two, at 

 common margin of segments 6, 7 in the same plane. From the posterior 

 base of the large teeth the abdomen tapers off to the cremaster in converging 

 straight lines, the dorsal abdominal line being rather convexly curved and 

 slightly earinated, the carination rising into a small tooth at the anterior 

 margins of segments ; cremaster narrow, square at extremity, very shortly 

 bifid ; the bead snout, abdominal, supraspiracular ledge and the ledge in 

 continuation anteriorily with a covering of very short, bristle-like hairs ; 

 surface of pupa besides is somewhat roughened by pitting with the excep- 

 tion of wings ; segment 4 with a somewhat raised, small, roughened, dorsal 

 patch. The wings are only slightly convex ventrally. Spiracles of segment 

 2 indicated by an oval, flat surface facing forward formed by the raising, 

 convexly, of a small portion of the front margin of segment 3 above the 

 hinder margin of segment 2 ; the rest rather large, oval, white, situated 

 below the ledge or segments 6, 7 and a yellowish line along abdomen. 

 Colour of body a darkish bluish green or grass-green, wings greenish white 

 as also ventrum of abdomen ; segment 2 as well as top of snout whitey- 

 brown ; the carina of thorax the same whitey-brown with a fine, double, 

 black line along summit which is not continued anteriorly beyond apex ; 

 carina of segment 4 similar in colour with similar black line ; flat portions 

 of segments 6 and 7 whitey-brown ; the points of all teeth black ; a yellow, 

 supraspiracular, abdominal line along the narrow ledge. L : 20 nun.; L. of 

 snout 1-5 mm. ; B : 7 mm. between points of teeth of segment 7 ; 4-5 mm. at 

 shoulders ; H : 5 mm. at apex of thorax. 



Habits. — Huphina phryne is a very common butterfly in nearly 

 the whole of its range. The larvae are easy to find wherever it 

 exists. The eggs are always laid singly anywhere upon the
