PTEROPHORUS GALACTODACTYLUS. 375 



about five-eighths of an inch long, and of average 

 proportions ; the thorax and head are rounded above, 

 flattened beneath; the head is bluntly rounded off; 

 the leg- and wing-cases extend halfway down, but 

 are detached from, the abdomen. The ground colour 

 is bright green ; two distinct white stripes extend 

 from the thorax to the tip of the abdomen, and 

 outside these stripes, on each side of the first two 

 abdominal segments, are two conspicuous black spots, 

 one on each side, and there is a faint indication of 

 similar spots also on the other segments ; as in the 

 larva, each tubercle emits a tuft of grey hairs. (George 

 T. Porritt, 5th April, 1881 ; Entom., May, 1881, XIV,

Plate CLXIV, fig. 7. 



On the 3rd of September, 1878, I received two 

 larvse on Marrubium vulgare, assimilating remarkably 

 well to the plant, and very sluggish. 



They were not quite half an inch long when 

 stretched out, tapering a little from the third segment 

 to the head and very little at the three hinder seg- 

 ments; the ventral and anal legs were slender, these 

 last stretched out behind in line with the body ; the 

 head was small, pale whity-brown freckled a little on 

 the face with dark brown; the head was roundish in 

 shape; the segments were plump and deeply cut; the 

 second segment was rather long, of light ochreous- 

 green colour, very minutely freckled with dark brown 

 raised dots ; the rest of the body was rather inclining 

 to glaucous green and rather darker on the back than 

 on the sides ; a thin faint whitish dorsal line is just 

 visible ; besides the* trapezoidal projecting tubercles 

 of the back there are three rows of them along the 

 sides ; these are minute blunt cones, greenish, tipped 

 at the apices with darkish brown, and each having five
