10 HAUSTF.LLATA.-— LEPIDOFTERA. 



- triangle during repose ; anterior somewhat elongate and generally glossy ; 

 often repanded or a little falcate on the hinder margin : posterior ample, 

 rounded, sometimes emarginate on the hinder edge: legs in general 

 rather long, especially in the typical genera ; the intermediate and posterior 

 tilnce with a pair of spurs at the apex, the posterior sometimes with a 

 second pair in the middle. 

 Larvw with fourteen or sixteen legs, the caudal ones never deficient ; naked, 

 or bearing a few short hairs ; usually residing in a leaf twisted up by itself, 

 and in which it changes to a pupa, the latter elongate, frequently placed in 

 a strong cocoon. 



There is considerable diversity of habit amongst the insects of this 

 family, so much so, as to justify their separation into two groups, 

 one of which has four distinct palpi, the other only two ; some again 

 have the maxillie elongate, others almost obsolete : in a few the palpi 

 are extremely large, compressed and densely squamous ; and these 

 insects have the wings generally opaque and destitute of lively 

 colours; while the otliers have the wings mostly very glossy and 

 adorned with lively margaritaceous tints : it is evident, therefore, 

 that many genera exist amongst them, of which I shall endeavour to 

 give concise characters in a tabular form at the end of the volume. 



Genus CCXLVI.— Hypexa, Schrafik. 



Falpi two, porrected obliquely, much longer than the head, thickly clothed 

 with scales and compressed, triarticulate, the apical joint mostly ascending, 

 slender, acute, intermediate elongate, thickened towards the base, attenuated 

 to the apex, basal shorter than the apical, reniform : maxilluc rather long. 

 Antenna: alike in both sexes, pilose beneath, especially in the niides: liead 

 with a conical projecting tuft of hair between the antenna : eyes globose : 

 thorax rather stout : wings ample, anterior subtrigonate, with the hinder 

 margin repanded, the apex sometimes subfalcate; posterior slightly emar- 

 ginate : legs slender, simple ; coxce long ; tihiw rather short ; posterior with 

 two pair of spurs. Caterpillar slender, attenuated in front, with fourteen 

 legs : pupa inclosed hi a slight folliculus in a leaf convoluted by the larva. 



The species of this genus may be generally known by the bulk of 

 the palpi, which are very densely clothed with scales, compressed, 

 and with the terminal joint in general placed perpendicularly and 

 acute ; the anterior wings are sometimes subfalcate and transversely 

 faciated with dark streaks ; or repanded on the hinder margin with 

 elevated tufts in the centre of the disc : in other instances the palpi 

 are rather more slender, the thorax rather ample, the anterior wings
