MASONIA CRASSIORELLA. 807 



is practically continuous with Fumea but exhibits certain characters 

 which show that its species are more or less intermediate between 

 Bruandia and the former genus. The species that appear to belong 

 here are — crassiorella, afftnis, subflavella, saxicolella, edwardsella, and 

 mitfordella. The males of these species appear not to have yet 

 developed the long anterior tibial spurs of Fumea, although they have 

 progressed beyond Bruandia in this direction. They have retained the 

 greater number of antennal joints (as in the more generalised Bruandia 

 and Proutia) but the female (of crassiorella) appears in the tarsal 

 structure to be more modified than in Fumea. The cases are truly 

 Fumeid, covered with slender straws arranged longitudinally, and do not 

 present the mixed characters mentioned by Bruand as being noticeable 

 in B. comitella. Of the species noted, affinis appears to be most closely 

 allied to (if not a form of) crassiorella, saxicolella (noticed by Bruand 

 as a possible var. of comitella) does not appear to have been recorded 

 since Bruand's time, subflavella, described by Milliere, might very well 

 be synonymous with saxicolella, edwardsella is a species closely resembl- 

 ing subflavella but with fewer antennal joints (also from south-eastern 

 France), and mitfordella and hibemicella, which are separated by 

 Chapman, have, hitherto, been placed in British collections with F. 

 casta.

Original description.— Psyche crassiorella, Bruand (Fumea crassio- 

 rella, Gn. ? Nitidclla, Hiibn. Reaumur, torn, iii., Mem. v., pi. xi., fig. 8). 

 Envergure dumale 16mm.-17mm. Mas: alas oblongaa, flavo-brunnese, 

 nitentes; fimbria concolor, margine obscuriori. Femina: araneiformis, 

 omnibus sequentibus major. Involucrum : paleis longitrorsum positis 

 indutum, magnum. Eruca : pallide livida, strigis punctisque brunneis 

 anticorum segmentorum parte superiori gaudens. Caput nitens, colore 

 corneo, lineis necnon punctis brunneis (Bruand, Essai Mon. sur la 

 Tribu des Psychides, p. 92). 



Imago*. — Anterior wings 13mm. -17mm. in expanse; apex rounded; 

 distinctly oblong ; brown ; shiny ; a concolorous transverse fimbria 

 (seen only in certain lights) ; the outer margin rather darker ; wings 



* Crassiorella may be defined as 13mm. -17mm. in wing expanse, with 21-24 

 antennal joints, anterior tibial spur -66--70 (of length of tibia). This range does 

 not occur everywhere, some ratfes being of 15mm. -16mm., with 24 antennal joints 

 invariably, other races (e.g., the, English) having from 21-23 joints (Chapman).
