It approaches group 11 (Lozogramma) . Superior wings rather narrow, acute 

 at the apex, slender and silky ; bone-white, with the fringe concolorous, preceded 

 by little rounded interneural black dots ; a similar dot in the cellule j a black lon- 

 gitudinal lino parts from the base, and is directed towards the apex, which it does 

 not reach, conspicuous above, but obliterated beneath : inferior wings equally nai'- 

 row, somewhat prolonged at the anal angle, paler than the superior, and without 

 markings. Auteunaj furnished with fine, but long, ciliatious. Front glossy and 

 rounded. 



Genus Fidonia. 

 FiDONiA (?) SERVULARTA, Guenee, n. s. 



Ales omnes pahacecc, nitentes, margine fasciaque terminali interrupta 

 nigro-griseis ; linea media jnmctoque cellulari : suhtus co7icolores, fascia 

 media pallida. Antcnnce peciinatcd. Palpi aczUi. Corpus gracile. 



I have only one sex of this small species, and dare not affirm that 

 it really belongs to the Fidonidce. It has a deceptive appearance of an 

 Acidalia. 



All the wings are entire, shining, straw-yellow with blackish markings, form- 

 ing at first a common border, which is rather unequal, and afterwards another 

 similar unequal band on the superior, greatly interrupted, and leaving sometimes 

 only a line on the inferior : the superior have, in addition to the elbow line, a cellu- 

 lar dot and two markings on the inner margin : the under-side of the four wings 

 have the markings of the upper, and a distinct median band of the ground colour 

 is there seen, but the colour is paler on the inferiors. Body slender, concolorous. 

 Antcnnce furnished with long pubescent pectinations. Palpi forming a moderately 

 prominent, but veiy acute, beak.

Occurrence in England of the larva of a terrestrial Trichopterous insect; prooahhj 

 Enoicyla pusilla, Burmeister. — I have several times called attention to the existence, 

 on the Continent, of a Caddis-fly {Enoicyla pusilla) which, in the larva state, lives 

 out of the water amongst moss at the roots of trees ; — the exception in these insecta 

 which proves the rule. I believe I can now assert that this is a British insect. 

 Mr. Fletcher, of Worcester, has obligingly sent me several living larvse and their 

 cases found in the moss and lichens near the root of willow-trees, and these cases 

 exactly resemble those of Enoicyla pusilla, from Bavaria, in my collection : they 

 are of a very ordinary form — slightly curved cylinders made of fine sand. It only 

 remains to breed the insects (which should appear late in the autumn) to enable 

 us to add this most interesting species to the British Fauna. As might naturally 

 be expected, the larva is destitute of the external respiratory filaments common to 

 almost all caddis-worms, but the spiracles are not very evident. E. pusilla is also 

 remarkable inasmuch as the female is wingless and little resembling the male. 

 Several authors, before its transformations were shown, remarked on the occuirence
