wish gratified, for it seems always to blow on these plains outside Bogota. I took a 

 walk a few days since, with net in pocket, and had another interview with Nathalis; 

 but shall try and secure you a box of duplicates, and so settle the question of the rarity 

 of this species for the future. A few Colias Dimera I have also taken for you ; they 

 are abundant, but many are out of condition — a day or two, perhaps, suffices to do 

 this, as the /ellows fly like Tam O'Shanter before Cutty Sark. You tell me at least 

 a hundred species of Papilio are known " from Bogota." Nothing very alarming in 

 that, if I have sent thirty-six species. How many single collectors have done more, 

 and how mauy have contributed to the hundred I should like to know. The Papilios 

 are the hardest to catch, and far from abundant at any time or place. What would 

 interest rne to know would be, how far my five hundred species represent proportionally 

 the whole number known from New Granada; that is, whether the several classes or 

 orders are in fair proportion to each other, or if the list indicates that I have looked 

 chiefly to any particular class : I know the butterflies do not think so. There are some 

 fellows I do not often trouble, such as Heliconia Erato: he is a fellow who knows he 

 is common, and is always poking his nose in, secure in his worthlessness, and hoping 

 to call you off from better game. You fancy I do not worry the whites, do you? 

 eighty-one species of Pieridce cannot be very bad. — Henry Birchall; Boyola. 



Description of the Larva of Ennomos fuscaiilaria. — The larva may be generally 

 described as elongate, with the true legs well developed, the third pair being sometimes 

 of large proportions, and with two anal points. The variety which I first set eyes on 

 gratified a crotchet of mine, inasmuch as it resembled the leaf-stalk of the ash, from 

 which tree I beat it. In figure it was smooth; in colour it was green on the back, 

 with a subdorsal stripe of yellow; the spiracular stripe, primrose-yellow, reaching to 

 the mouth, and bordered aliove with deep gieen, which became lighter near the sub- 

 dorsal line ; the belly apple-green ; two little warts on the 12ih segment; the true legs 

 black, ventral legs tipped with crimson-brown, and the anal legs green. This I thought 

 was the invariable pattern of E. fuscanlaria, but last summer Dr. Knaggs sent me six 

 larvae to rear for him, and I found that at their last moult some of them developed an 

 entirely different appearance; to wit, the ground colour was reddish gray, slightly 

 mottled with greenish ; subdorsal yellow stripe scarcely visible; spiracular line rather 

 greener than the ground colour, and becoming yellowish from 2nd segment to the 

 mouth; across the 3rd segment was a row of red-brown warts, the largest being on 

 the sides; large transverse red humps on 6lh and 9th segments, and a very small one 

 on 8th and 12th ; lateral red warts on 5th, 6Lh and 7tb, and a ventral hump on 7th ; 

 pale lateral warts on 10th, 11th and 12lh; the true legs crimson-biovvn, the third pair 

 being very large. And Mr. Doubleday sent Mr. Buckler another larva, which appears 

 intermediate between these two. It was nearly smooth, the ground colour a pale apple- 

 green, subdorsal and spiracular lines yellow, but not clearly defined; the last five seg- 

 ments suffused with ])ink ; two small red spots placed on a swelling at 7th segment; 

 two dorsal warts on r2th ; small lateral warts on lOlh, 1 1th and 12lh ; on 3id segment 

 a short red-brown stripe running backwards from the spiracles to middle of the back. —

Description of the Larva of Nonagria Typhce. — Larva elongate, brownish ochreous ; 

 head reddish brown, a shining plate of the same hue on the 2od segment ; two fine 

 dusky lines run down the centre of the back to the posterior segment, which is dark 

 brown. There are two pale ochreous stripes along the sides, aud below them are 

 placed the black spiracles; belly and prolegs paler; the anterior legs whitish, tipped
