190 Mr. R. MacLaclilan's Monograph of 



Wincjs slightly ochreous, sub-hyaline ; anterior wings 

 transversely clouded with grayish fuscous, especially on 

 the apical margin; neuration with whitish and blackish 

 spaces in regular alternation ; seven sectors ; twelve vein- 

 lets in the outer gradate series, six in the inner, and about 

 five towards the base : posterior ivings whitish, iridescent, 

 broadly margined with grayish fuscous ; neuration mostly 

 pale on the disk, and fuscous on the margin. 



Length of body 3 lines ; expanse of wings 7 lines. 



Very rare. The above description is made from the 

 example figured by Curtis, which was taken on the 1st 

 July, 1825, at Duddingston, near Edinburgh, by Mr. 

 J. C. Dale. Another example is in the British Museum, 

 and probably one or two other native specimens are in 

 existence. 



The appendices of the male are not prominent, but 

 there would appear to be a broad rounded dorsal and 

 ventral plate at the apex of the abdomen. Mr. Dale's 

 example would seem to be a female, in which the abdo- 

 men is simply obtuse at the apex, and I have only seen 

 Continental males. Possibly several species of the genus 

 exist in Europe ; but, excepting the one with which ours 

 seems to be identical, they are little known. Linnets 

 type still exists in his collection, and bears the label 

 " hirtus " in his own handwriting ; it agrees in every 

 particular with the English examples. 



Genus VII. Deepanepteeyx, Leach. 



In general character similar to Hemerohius, but more 

 robust in form; the last joint of the maxillary palpi 

 stronger, only slightly acuminated. 



Wings falcate, the apical margin strongly excised, 

 especially in the anterior pair. The costal area of the 

 anterior ivings is very broad at the base, the costal veinlets 

 very numerous, and united by two longitudinal rows of 

 connecting veinlets ; sectors extremely numerous ; three 

 complete series of gradate veinlets ; neuration and mar- 

 gins very shortly ciliated. The costal margin of the pos- 

 terior wings has a similar elevation to that in Megalomus.
