DESCRIPTIONS OF THE LARYA AND PUPA OF APROMREMA 

 8ANOIELLA, Stn. 



BY EUSTACE R. BANKES, M.A., E.E.S. 



The larva of Aprocerema Sangiella, Stn., has heen already described 

 bj Stainton in Ent. Ann., 1867, p. 21, but as his description, which is 

 copied by Meyrick in his Handbook, is very brief, a more detailed one, 

 made on May 15th, 1896, from nearly full-fed larvae kindly sent me 

 from Co. Durham by Mr. J. Gardner, may be useful. 



LARVA. 



Length, 7 — 8 mm. Greatest breadth, 1'7 mm. 



Head considerably narrower than the prothoracic segment, liighlj polished, 

 amber-yellow ; mouth parts reddish ; ocelli black, distinct. Prothoracic segment 

 with a highly polished blackish plate divided across the centre by a whitish line. 

 The incisions which precede and follow both the prothoracic and tlie mesothoracic 

 segments are conspicuously greenish- or yellowish-white. The thoracic and abdo- 

 minal segments viewed together form a short stumpy mass, very stout in the middle, 

 and tapering much and rather suddenly towards both extremities, rather dark 

 reddish-brown, occasionally brownish-red, with a whitish or yellowish-white dorsal 

 line on the thoracic segments. Tubercles and spiracles very small and inconspicuous, 

 black, polished, emitting pale hairs. Anal plate small, polished, blackish. Ventral 

 surface yellowish red-brown, with some minute black polished tubercles. Legs 

 highly polished, horny, externally black, with the joints pale ringed, internally much 

 paler. Frolegs semi-transparent, yellowish-white. 



The larva lives in a neat habitation formed by drawing together 



with silk the edges of the topmost outer leaves of a shoot of Lotus 



cornicidatus, and feeds on the tender heart of the shoot, moving readily 



from one sprig to another. A few of the larvae received were still 



small, but all alike were very similar in colour and markings to those 



described above. 



PUPA. 



The following description was made on May 25th, from pupae 

 which had assumed that state only a few days previously : — 



Length, 5"5 — 6 mm. Greatest breadth, 1'7 mm. 



Rather short and stout, brownish-orange, with the wing-cases and ventral sur- 

 face of the anterior segments rather paler ; the abdominal segments, and, to a less 

 noticeable extent, the other parts are clothed with a short whitish pubescence. 



Head rather broad and flattened above, rounded in front. Ei/es showing 

 through as black spots. Wing-cases reaching to the end of the fifth abdominal 

 segment, and of almost equal length with the antennal cases which lie between 

 them. The shape of the last three segments when viewed together reminds one of 

 that of the sharpened end of a common pencil, the seventh abdominal segment
