Aphrodes sahulicola, Curt. B. E. 633. fig. 



The irregularity and instability of the markings somewhat baffle 

 description, but the milk-white cruciform figures formed by the anas- 

 tomoses of the nervures, with ziczac spots between, are the most obvious 

 character. The description is from a well-marked specimen. It is very 

 like formosiis, Boh,, but the vertex in that insect is as long as the 

 pronotum. Kather common on the sand hills at Freshwater Bay, 

 Pembrokeshire, August — September : sent also to me by Mr, T. J . 

 Bold from Northumberland ; Curtis's examples were from the sandy 

 coast of Lowestoft. The figure in B. E. represents a rather imperfectly 



marked individual. ^ _

DESCRIPTION OF A GENUS OF CADDIS-FLIES, OF WHICH THE LARV^ 

 CONSTRUCT CASES KNOWN AS HELIC0P8YCHE. 



BY DB. H. A. HAGEN. 



Genus Helicopstche, Bremi. 



Spurs 2.4.4, The external spur on the anterior tibise very small, 

 the internal strong, one half shorter than the first tarsal joint ; the 

 spurs on the other tibiae strong, half as long as the first tarsal joint, the 

 external rather shorter than the internal, especially on the intermediate 

 tibiae, placed a little before the apex. 



Maxillary palpi of the male clothed with long and thick hairs, 

 stout ; first joint short ; second long and broad, straight ; third slightly 

 shorter, curved, thinner ; these palpi are curved upwards, the tliird 

 joint flexible (or changed in form in drying ?). Labial palpi short, the 

 joints somewhat widened in the middle, flattened, the basal joint slightly 

 shorter than the others, which are equal. 



Maxillary palpi of the female nearly as hairy as those of the male, 

 the second joint slightly shorter, the succeeding ones successively 

 shorter, the terminal thinner. These palpi in the female at first sight 

 appear similar to those of the male, but on closer examination it is 

 found that the part analogous to the third joint in the male is divided 

 into three ; they are longer than the head.
