HYLOTOMA GRAOILIOORNIS. 53 



This species has a more slender body than any of 

 the other species of the same coloration, and is easily 

 known from them by the head not being dilated behind 

 the eyes, by the more oblique third transverse cubital 

 nervure, by the third cellule being more dilated on 

 upper side, and by the longer and more slender 

 antennae. 



The larva feeds on Rubus iddeus during August and 

 September. Its head is pale brownish -black, paler in 

 front, and especially above the mouth, which is brown. 

 Legs white, encircled with black at the base ; first is a 

 black ring, then a large broad one, and in front is a 

 small black dot. Claws brown. Claspers white. 

 Body dirty green, with a whitish tinge. On the back 

 are two rows of black dots in the centre ; on the sides 

 are other two rows ; below there is a row of large orange 

 marks, eight in all, the first commencing over the third 

 pair of legs ; over each clasper is a large black dot, and 

 over a number of them are some minute black dots, 

 there being also some small dots close to the large 

 yellow marks ; the second segment is orange. From 

 each of the black dots there issues a small hair. When 

 very young, the orange marks are wanting ; they only 

 appear after the second moult. Zaddach describes the 

 ground colour as reddish, but I have not noticed this 

 colour, except occasionally along the back, and thought 

 it was caused by the food. The larva pupates in the 

 earth. 



Near the larvae I have noticed Proterops nigripennis, 

 which is no doubt a parasite on them. 



The perfect insect appears in June in Scotland, in 

 May in England, and is not common. Gadder Wilder- 

 ness, near Glasgow, Coombe Wood (Stephens). 



Continental distribution: Sweden, Germany, France, 

 Switzerland. 



Obs. Klug describes cfracilicornis as having the antennae reddish, 

 but this is not a point of any value in specific discrimination.
