TENTHKEDO BICINCTA. 91 



This insect is known from licincta by its much 

 larger size, yellow scutellum, anal segment having 

 only a very small patch of yellow, the yellow posterior 

 tarsi, there being only a black band on the apex of the 

 metatarsus ; the clypeus is not so deeply notched, 

 patellae are much more strongly developed, antennas 

 are longer in proportion, and not so much thickened 

 at the apex, and the pubescence on the head is much 

 longer and thicker. 



The coloration in the ? is tolerably constant, but 

 in the 3 it varies considerably, especially on the 

 thorax and legs ; in some individuals only the sternum 

 is black, while in others the pleurae are more or less 

 of that colour ; so also the femora may be either quite 

 black or with only a slight irregular black line, and 

 the abdomen may be entirely yellow or with a black 

 patch at the base and apex. The tibiae, too, vary in 

 the same way as the femora. 



Maculata does not seem to be a very common insect. 

 I have taken it on oak near Glasgow ; it is met with 

 in Darenth Wood, and some other metropolitan situa- 

 tions, also in Devonshire. It is found towards the 

 end of June and beginning of July. 



Nothing definite is known about the larva, although 

 Dours (Cat. Syn., 24) says that it feeds on the oak. 



It occurs in Germany, Hungary, France, Switzer- 

 land, Italy, and Kussia.
