34 CLADIUS PADT. 



Black ; antennse setaceous, nearly as long as the body. Head covered 

 with fuscous down, frontal sutures very distinct, epistoma keeled; 

 mandibles piceous, palpi pale testaceous. Thorax shining, covered with 

 scattered greyish down ; cenchri large, dull white ; tegulse piceous, 

 more rarely pale. Abdomen covered with scattered pubescence ; 

 cerci longish. Wings sub-hyaline, with a smoky tinge (varying in 

 different individuals), costa pale, stigma fuscous. Legs white, base of 

 coxap, femora in the middle, and often the posterior tarsi with the apex 

 of tibiae black. Calcaria longish. 



The <$ has the antennse strongly compressed, pilose, and a little 

 shorter than the body. 



Length 2 2| lines. 



G. padi is to be recognised by always having the tro- 

 chanters and base of coxae white, by the keeled epis- 

 toma, longish cerci and calcaria, and pilose antennse. 

 In the coloration of the legs four aberrations occur. 



a. Femora entirely white. 



b. Femora with a fuscous splash in the middle. 



c. Femora nearly all black. 



d. Posterior tarsi and apex of tibiae black. 



Also in many specimens the colour is testaceous, and 

 may have a yellowish tinge. The wings vary in the 

 amount of smoky tinge with which they are suffused, 

 and the tegulae vary from black through testaceous to 

 white. 



Larva : head covered with longish hairs ; light 

 orange brown, spotted over with small orange dots ; 

 eye-spots black, a black roundish mark on vertex 

 extending to the extreme back of the head ; mouth 

 reddish-brown with black mandibles. Legs white, 

 claws brown. The ground colour of the body is 

 usually green, varying to grey ; the sides are clearer, 

 almost white, and the last two segments are also white. 

 The skin is beset all over with tubercles, each ending 

 in a long hair. 



When young the larva has the colour not so deep, 

 and the body has often a reddish tinge, especially when 

 the food-canal is filled. In old larvae the colour of the 

 head varies very much ; sometimes it is quite orange, 

 at other times almost black, and often the black mark 

 on the vertex is absent. 



The eggs are laid about the beginning of May, on the
