THE GROUP OF MYOSOTIDIS. 129 



apex, the antennal fovea is very distinct, while the 

 curved furrows which come down on either side of the 

 antennal fovea, and are so conspicuous in N. glutinosce 

 and miliaris, are scarcely noticeable ; the cenchri are 

 smaller, the antennae thinner. 



The larva has the body dark green. The head is 

 green. In centre of head is a long black line, which 

 reaches near to the mouth ; above, over the eyes, is a 

 much shorter lateral line. Over the legs is a blackish 

 waved line, and above that again is a less distinct 

 line. On the thorax are some tubercles ; while over 

 the anus is a black, sometimes more or less reddish, 

 mark, cleft and broader behind than at the apex ; the 

 cerci black. A thin white line runs through the 

 spiracles. 



The larva of N. salicivorus may be known from that of 

 N. miliaris by the much longer central stripe, and 

 shorter lateral stripe onface,by the less clearly indicated 

 black stripe on the sides above, by the clearly indicated 

 waved lines over the legs, by the legs wanting the 

 oblique black mark in front of them found in miliaris, 

 and by the distinct black mark over anus. In habits 

 they are identical, and are sometimes found feeding 

 on the same bush.

XIV. THE GROUP OF MYOSOTIDIS. 



Black, pronotum more or less, abdomen and legs, 

 yellow; the former blade at base, or on the whole 

 dorsum. Antenna longish, pilose, especially in <$ , black, 

 sometimes brownish beneath; first transverse cubital 

 nervure absent or nearly so ; costa and stigma luteous 

 or testaceous; clypeus incised. 



In only one species are the pleurao and sternum 

 testaceous. From the preceding section the difference 

 in coloration distinguishes it ; from the succeeding the 

 incised clypeus.
