case) within the larval case, and are mixed with hairs from the anal tuft, 

 and, like those of the rest of the Micro- Psychids, the pupa-cases of both 

 sexes protrude from the puparium. Structurally the larva has, in the 

 migration of the posterior trapezoidal tubercles (ii) behind the anterior 

 (i), reached a higher Psychid plane than Divlodoma and Solenobia, 

 whilst the pupa is of distinct Micro-Psychid type. There are but few 

 species described as belonging to this family, and even of those in- 

 cluded by various authors in the genus Taleporia, some appear to be 

 wrongly placed. We have in Britain only one generally recognised 

 representative in each genus. In Taleporia we have tubulosa, in 

 Bankesia — staintoni, Walsm., hitherto known as conspurcatella, Zell. 

 There is, however, the unique douglasii to be considered ; certainly it 

 appears to us to be distinct from any described Solenobia, and, so far 

 as one can judge from its superficial appearance, it is a Bankesia. 

 One, however, is unable with an unique specimen to risk the examina- 

 tion that would positively determine the matter.

The generic name Bankesia was first proposed in the Entom. Record, 

 vol. xi., p. 191, when conspurcatella, Sta., nee Zell. = staintoni, Walsm., 

 was cited as the type. - As the generic diagnosis had already been 

 drawn up, and was based on British examples of so-called conspurcat- 

 ella, since renamed staintoni by Walsingham, staintoni must be con- 

 sidered the true type of the genus. This genus, which is very distinct 

 from its allies, may be diagnosed as follows : 



Ovum. — Oval, surface smooth, delicate in texture, laid in larval ease. 



Case. — Large, coarse, trigonal in transverse section, covered with coarse sand, 

 pupa-case of both sexes protrudes at emergence of imago. 



Larva. — Head retractile ; thoracic segments also partially retractile, covered 

 with corneous plates ; true legs strong, a prominent rounded eminence bearing a 

 short thick hair between the true legs on either side ; the basal joint of the true 

 legs swollen, with strong ventral bristles ; prolegs short with oval of hooks broken 

 on inner edge ; the abdominal segments flattened ventrally, formed of distinct 

 plates ; the anal segment large, swollen, with large, triangular, corneous dorsal 

 plate ; tubercles i and ii trapezoidal, ii just outside i ; on the pro- and mesothorax 

 tubercles i and ii fused into one plate ; antennae 3-jointed ; eyespot with only one 

 (? two) ocelli discernible. 



Pupa. — Male : Dorsal head-piece moderate, labrum large and square, two hairs 

 on each side ; maxillse triangular, with a very large maxillary palpus ; mandibles 

 rounded, projecting; labium divided, the labial palpi project, divided for two- 

 thirds length ; antennas to end of wings, and wings to end of 5th abdominal ; the
