156 BRITISH LEPIDOPTERA. 



p. 197) the " Solenobee de Anderregg (Solenobia anderreggella) , and 

 figures the same. This insect is T. tubidosa {pseudobombycelld). In a 

 footnote to the generic name he writes : ' ' Nouveau genre etabli par 

 moi, et dont je donnerai les caracteres dans mon Catalogue Metliodique 

 a la fin de ce volume." On p. 198 of the same work he has a Solenobia 

 lefebvriella, which he also figures, and which appears to be a paler 

 form of T. tubidosa than his S. anderreggella. On p. 428 he has 

 Solenobia lichenella, and on p. 430 S. clathrella. These also are 

 figured, and undoubtedly represent the males of two species of the 

 restricted genus now known as Solenobia. On p. 512 there is a 

 Solenobia pectinella, which appears to be Luffia lapidella. 



As the Taleporia of Hiibner was created for tubidosa (pseudo- 

 bombgcella) and triquetrella, and Zeller restricted (his, 1839, p. 182) 

 the name to the former species, it follows that the insect first included 

 by Duponchel under the generic name Solenobia (viz., anderreggella = 

 lefebvriella = tubidosa) is not available as the type of the genus. This 

 leaves lichenella, Dup. (nee lichenella, L.), and clathrella, Dup., as typi- 

 fying the genus. Since the species of lichenella, Dup., is not absolutely 

 certain one prefers to name clathrella, Dup., as the type of the genus. 

 The genus, thus restricted, was diagnosed (Linn. Ent.,vn., p. 343) by 

 Zeller, as follows : 



Caput superne et in fronte hirsutum. Os pilosum palpis subnullis. Ocellis 

 nulli. Antennae <J setaceae ciliatae. Alae oblongae, mediocriter ciliatae ; anteriorum 

 cellula discoidalis venas in marginem posticum quinque eniittit, simplices ; ? 

 aptera, ano lanato. Larva saccophora, sacco breviusculo, granulato, anum versus 

 attenuate. 



The chief characters of the genus may be summarised as follows : 



Ovum. — Oval in outline ; shining, pearly-white in colour ; laid in case. 



Case. — Flattened ; convex above (sometimes slightly trigonal) ; lateral ridges 

 slightly angular ; soft ; mouth ventral, covered with sand and debris. 



Larva. — Head small, retractile ; pro- and mesothorax with chitinous plates ; 

 tendency to constriction between pro- and mesothorax ; thorax slender ; abdomen 

 bulky ; the anal segment with black chitinous plates ; dorsal tubercles i very 

 minute, ii larger (ii just outside i and some distance behind) ; iii large ; iv 

 (strong) and v (weak), both subspiracular ; true legs strong; prolegs very weak ; 

 crochets arranged in oval broken on inner edge ; spiracles inconspicuous with 

 slightly raised rim. 



Pupa. — Dorsal headpiece rather small ; two hairs at base of labrum (sometimes 

 2 or 1 other above) ; incisions 2-3 (dorsally only), 3-4, 4-5, 5-6, 6-7 (7-8 male) 

 movable ; the anterior patch of dorsal spines wide, including i ; i and ii trapezoidal ; 

 recurved hairs on abdominal segments 8-10 specially well-developed ; dorso-anal 

 spikes in both sexes ; proleg scars distinct ; spiracles with projecting rim. 



Imago. — Head rough ; tongue and maxillary palpi obsolete ; labial palpi short ; 

 eyes compound ; no ocelli ; antennae c? ciliated ; basal joint with pecten ; posterior 

 tibiae hairy ; ? apterous, with anal tuft. 



Netjration. — Forewings — lb furcate, 7 and 8 or 8 and 9 sometimes short- 

 stalked ; 7 to apex, 10 absent. Hindwings 4 and 5 or 6 and 7 sometimes short- 

 stalked (Meyrick). 



The Solenobiids differ from the Taleporiids in at least one impor- 

 tant character, viz., the absence of the imaginal ocelli. The pupa? of both 

 families are structurally very similar to each other, as also are they to 

 those of the Naryciids and Diplodomids, except that the latter, having 

 winged females, show considerable difference in respect to those organs 

 in the pupa, compared with the Solenobiid and Taleporiid pupa?. We 

 have already stated that the larval cases of Nargcia and Solenobia are 

 very similar, as also their larvae, but the winged female of the former 

 separates the families very sharply. Zeller separates the Solenobiids
