6^^ Indian Economic Bntomology. [ Vol, H, 



Wings entire. The scales on both wing-s are spai-seiy scattered. The fore 

 wing- has the whole space between the costal margin and the subcostal 

 nervure reddish ochre; the discoidal cell distinctly divided into three por- 

 tions by two interiineal uervules ; the whole spase between the submedian 

 nervure and the inner margin reddish ochre. All the rest of the fore 

 wing, with the exception of the following markings is semitransparent, 

 and powdered with fuliginous scales ; all the nervules are defined distinctly 

 with black; the interspace above the first discoidal nervule is white, basal- 

 ly ; there is a marginal triangular white spot in the interspace between the 

 first and second, discoidal nervules ; the first median nervule is bifurcated 

 from the base, enclosing a large marginal quadrate spot ; there is a sub- 

 marginal black patch connecting the lower branch of the first to the 

 second median nervule; there are also pale spots along the margin between 

 the second and third median nervules, and the third median nervule and 

 submedian nervure. The hind wing is semitransparent fuliginous, with 

 the nervules only slightly darker ; the base of the wing is clothed with 

 long dark brown hairs. The antennae are highly pectinated *and are about 

 a third of the length of the fore wing. Eyes smooth. Legs densely 

 covered with hair. Thorax whitish buff with central and subdorsal 

 black longitudinal bands. Abdomen covered with dark brown hair. 



The female, which never completely ennerges from the pupa shell, unless 

 by accident, until it has laid all its eggs, is simply a skin full of ^g^^, 

 with a scutellate formation at the head end, and an ordinary ovipositor and 

 sexual organs at the other. My figure gives a correct representation, 

 magnified 2| diameters, of all that is visible outside the pupa case. 

 There does not seem to be any trace of any limbs or features, which are 

 present in the male. The head end consists of a sharp beak-like protu- 

 berance, with an edged under surface, followed by two short pointed 

 processes on a wrinkled hard surface. The backs of the thoracial segments 

 are covered with a hard shell-like formation, of a light brown colour, re- 

 sembling the pupa shell, but smoother and lighter coloured. The abdo- 

 men is of a pale buf£ colour, with a broad dorsal and narrower lateral 

 yellowish line, extending throughout. There is a ring of tawny velvety 

 scales round the last segment but one, formed of extremely fine scales and 

 the end of the abdominal part of the pupa shell is filled with loose scales of a 

 different shape, which the insect drives out of its pupa shell by means of 

 its maggot-like contortions. I believe that the expulsion of these scales 

 serves to attract the male, and they are probably odoriferous ; they are also 

 used to cover the eggs, which are always laid inside the pupa shell. Some 

 collectors have thought that the part of a female Psychid moth which 

 protruded from the cocoon was the sexual organ, but had they seen a male 

 copulating with the female, they would at once have recognised their 

 mistake. Indeed, the head end has at first sight somewhat the appearance 

 of some insects' sexual organs.
