Description of the larva af Miana furuncula. — For the discovery of the larva of 

 this insect we are indebted to Mr. J. Gardner, of Hartlepool. During the first week 

 in May last, he found a number of Miana larvse feeding on Air a ccesjntosa, which he 

 at once suspected belonged to furuncula. Seven or eight of them he forwarded to 

 me, and on seeing them I had little doubt as to the correctness of his suspicion. 

 This proved correct, as, although I was unsuccessful in getting a moth from my larvse, 

 on the 19th July, Mr. Gardner was fortunate enough to breed the species from those 

 he had retained for himself. 



Length, about three-quarters of an inch, and of the usual Miana shape : head 

 small, and very much narrower than the second segment ; it is brightly polished, has 

 the lobes rounded, but is pointed at the mouth. Body cylindrical, attenuated towards 

 both extremities from the fourth segment, which is the widest : there is a polished 

 plate on the front of the second, and another on the anal segment : skin smooth, but 

 tough and rather glossy, which gives the larva a mealworm-like appearance. 



The ground is a very pale straw colour, in some specimens strongly tinged with 

 purple ; head brown, the mouth still darker brown ; the pale yellow pulsating 

 alimentai'y canal forms the dorsal line ; there are no perceptible sub-dorsal or 

 spiracular lines ; the plates on second and anal segments are a paler shade of brown 

 than the head : spiracles large and round, intensely black. The only other marking 

 is a faint purplish marbling in the centre of each segment, on each side of the dorsal 

 line. Yentral surface and pro-legs uniformly of the ground of the dorsal area ; the 

 legs brown. 



The cocoon is made inside the larger sheaths of the stem, near the root, and 

 is rather strongly formed of little bits of the drier grass bitten out and cemented 

 together. 



The only Miana larva now undescribed is expolita, and I hope this may be set- 

 tled next year, as Mr. Gardner, after a great deal of trouble, has supplied me with 

 eggs of this species also : these hatched about ten days ago, and I hope the young 

 larvae aregoing on well. — Geo. T. Poeeitt, Highroyd House, Huddersfield : Aug.

Chrysopa tenella, Schneider. — Hagen, in his "Synopsis of the British Plani- 

 pennes," published in the Entomologists' Annual for 1858, included this species in 

 the British List with doubt, on the authority of a single example in the British 

 Museum. I omitted it in my " Monograph of the British Neuroptera- Planipennia" 

 (Trans. Ent. Soc. Lond., 1868), but introduced it in the Catalogue of British 

 Neuroptera, published by the Entomological Society in 1870, on the authority of a 

 specimen taken by Mr. Wormald at Hampstead. It has since been found by me 

 several times, and the indications of localities and dates are as follows: — Weybridge, 

 4tli July, 1874; Tunbridge Wells, 28th July, 1874; Darenth Wood, 3rd June, 1878; 

 Weybridge, 17th June, 1878 ; Southborough, near Tunbridge Wells, 30th July, 1878. 

 (One example from near Plymouth, end of August, 1877, is doubtfid). On one 

 occasion I found two examples on the same day, but otherwise it has only occurred 

 singly. Schneider originally described it from a single example captured by him in 

 the botanical garden at Breslau and I should say it is always scarce, judging from 

 the paucity of examples from the Continent seen by me. It is a delicate little species, 

 and the pale yellow (or whitish) dorsal vitta in living specimens gives it a resemblanco
