The pupa is a full inch in length, by four and a half lines in width 

 at the thickest part across the ends of the short wing covers, the 

 antenna-cases well developed ; the head and thorax smooth, the wing 

 covers most minutely roughened, also the upper portions of the 

 abdominal rings, the free segments of the abdomen are very deeply 

 cut and gradually taper towards the end, but with dissimilar outline 

 ou the ventral and dorsal surfaces ; the ventral becoming bluntly 

 rounded, and the dorsal rising somewhat in a hump from which springs 

 the base of a prolonged stout spike, whose blunt extremity is furnished 

 with two fine tapering points bent downwards and curved like claws ; 

 the colour is a deep and dingy red during the first year, and in the 

 second becomes a blackish-brown, bearing a slight purplish gloss.

Entomological collecting during a voyage to the Pacific Cconchided). The genus 

 JPapilio was represented by twelve species, tlie commonest being P. Philenor, a hand- 

 some black " swallow-tail," glossed with rich bronze-green, and with a curved row of 

 large, round, bright orange spots ou the hind-wings beneath. Two or three very- 

 showy red-spotted black species were also fairly plentiful in the lanes, and two or 

 three very beautiful and delicate-looking semitranspareut species with very long tails 

 (related to the South American P. Protesilaus, &c.) also occm'red, but were very hard 

 to obtain in perfect condition. The large and handsome Gonepteryx Clorinde 

 occurred sparingly, as did the beautiful sulphur and black Colias Casonia ; and seven 

 or eight species of Terias, including some fine orange-coloured ones, abounded in all 

 the more open places. Settling on tree-trunks, I found three species of Ageroma, 

 Smyrna, sp., and two of Siderone, the latter, however, being represented by single 

 worn specimens. Marpesia Thetis was often seen, but persisted in keeping well up 

 out of reach of a long-handled net ; Eresia, JEuptoieta, MelitcBa ?, and Phyciodes 

 were well represented in grassy openings and cocoa-nut groves ; and by road-sides 

 I took several specimens of the singular Lihythea Carinenta, with its excessively 

 long palpi. A lovely specimen of Bihlis, quite distinct from the one found at 

 Panama, occurred singly at a thicket, and several fine ErycinidcB, TheclcB, and 

 skippers, some of the latter being very large and handsome, complete my list of 

 captures. I noticed comparatively few moths, though there were some pretty little 

 day-flying Bombyces among them. Beetles were fairly numei'ous, though mostly 

 small; but I got some nice Lycidcs and CassidcB, one ov two Cetonice , &\\A. oth.ev 

 interesting species. 



Leaving Acapulco ou June 23rd, we anchored off the miserable little port of 

 San Bias ou the evening of the 26th. The town, which is notoriously unlicalthy, is 

 built on about the worst site it is possible to imagine — a flat strip of sand only 

 four or five feet above high-water mark, shutting off the inner harbour, a mere 

 shallow lagoon, from the sea, and with pools of foul-smelling stagnant water in many 

 places among the houses. We stayed at this delightful spot only twenty-four hours, 

 but I was able to get a short walk on shore for about two hours in the early morning
