. Species 6.— Batia Panzeeella— (Donovan, 3, PI. 106, fig. 4 ? "Wood, fig. 1431, and our Plate CXIV., 

 Fiw. 22) — Expands 8 to 9 lines ; (15 lines, according to Mr. Curtis,) fore -wings yellowish ash, or ochreous, and 

 immaculate ; hind wings pale brownish, with paler fringe. Near London. 



Species 7. — Batia flavifrontella — (Fabricius, &c. ; Wood, fig. 1432, and our Plate CXIV., Fig. 23) — 

 Expands 9 to 10| lines ; (12 lines, according to Mr. Curtis,) fore wings ashy, with a slight ochreous tinge, and 

 occasionally with one or two dusky dots on the disc ; hind wings obscure ochreous, with a yellowish fringe ; head 

 dirty yellow. Darenth Wood, and Camber well, but rare. 



TINE I D^, Stephens. 



The insects comprised in the present family are distinguished from the Tortricidse by their narrower wings, as 

 well as by the slenderness of their labial palpi, whilst the great development of the maxillary palpi, and the rare 

 occurrence of recurved labial palpi separates them (but by no means satisfactorily) from Yponomeutidse. The 

 body is generally long and slender ; the head often densely clothed vrith scales in front ; the antennae of moderate 

 length, and slender ; the spiral tongue short, the thorax is rarely crested, the legs spurred in the usual manner ; 

 the wings are entire, often very narrow, and mostly convoluted in repose, the hind ones of moderate size, and 

 much folded when at rest. 



In their preparatory states these insects are variable in their habits, but their larvae are generally naked or 

 setose, many residing in portable cases, formed of various materials, in which they undergo their transforma- 

 tion, whilst others feed upon vegetable substances, some residing within the stems of plants, and others 

 subsisting upon the leaves ; a few, however, are sub-cutaneous, feeding in the interior of leaves. In their 

 perfect state they are mostly of a larger size than the minute gilt species belonging to the preceding family, and 

 in their colouring they rarely exhibit any of that brilliancy of gold and silver with which so many of the latter 

 are ornamented, their usual tints being rather sombre, such as ochre-white or buff, with irregular longitudinal 

 marks or streaks. We know nothing of the exotic species of this and several of the preceding families, nor 

 of their transformations ; our arrangements must therefore be considered as unsatisfactory. Mr. Duponchel has, 

 however, divided them into sixteen groups, according to their habits in the preparatory states, in his memoir, 

 published in the Annals of the Entomological Society of France for 1838. 



ACHROIA, HuBNER. 

 The insect forming the type of this genus, has much of the habit of the genus Lithosia, but with the wings 

 more rounded, and entire ; the palpi are very short and almost concealed by the scales of the front of the head ; 

 the antennoB are short, the body slender and rather elongated, and the fore wings horizontally incumbent 

 during repose, and of plain hues. The caterpillar feeds on the honey in bee-hives, sometimes greatly damaging 

 the comb as well as destroying the inhabitants. It is fleshy and slightly hairy, and forms a cocoon of very 

 white silk, which is covered with minute black grains of its excrement. 



Species 1. — Achroia alvearia ' — (Fabricius, &c. ; Wood, fig. 1433, and our Plate CXIV., Fig. 24) — 

 Expands 8 to 11 lines ; entirely pale brownish ash ; fore wings rather darker, with a yellow head. Taken in 

 June in the neighbourhood of beehives, but rare.
