embraces it with the ventral claspers, the anal extremity, 

 together wilh the anal claspers, remaining extended. Head 

 glabrous, scarcely notched on the crown, narrower than the 

 2nd segment, into which it is partially received : body cylin- 

 drical, but slightly attenuated towards both extremities ; anal 

 claspers spreading. Colour of the head pale dull olive-green, 

 inconspicuously reticulated with darl<er lines : body pale dull 

 olive-green, sometimes exhibiting a shade of gamboge-yellow; 

 the dorsal and ventral areas are abruptly divided on a level 

 wilh the spiracles, which are intensely black ; dorsal slightly 

 darker than the ventral area, and having also three darker, 

 but nevertheless very inconspicuous, stripes ; one of these is 

 medio-dorsal, and intersected throughout by a slender paler 

 stripe ; the others are lateral and immediately above the 

 spiracles : legs and claspers concolorous with the ventral 

 area. When full-fed it descends to the ground, and changes 

 to a pupa just beneath the surface of tlie earth. The moth 

 appears on the wing in June, I am indebted to Mr. Double- 

 day for these larvae, which were full-grown on the 31st of 

 August. — Edward Newman. 



Description of the Larva of Hecatera serena. — The larva 

 feeds on the blossoms and seed of the garden lettuce : it 

 rests in a straight position on its food-plant, but falls to the 

 ground when disturbed, and, tucking its head under the 

 body, embraces it with the ventral claspers, the anal ex- 

 tremity, together with the anal claspers, remaining extended. 

 Head glabrous, scarcely notched on the crown, narrower 

 than the 2nd segment, into which it is partially received, 

 emits a few slender bristles : body cylindrical, but slightly 

 attenuated towards both extremities ; anal claspers spread- 

 ing ; there are a few minute warts, each of which emits a 

 fine bristle, scattered about the body. Colour of the head 

 dull pale greenish brown : of the body dingy yellow-green, 

 the dorsal and ventral areas being divided by a very distinct 

 yellow-green stripe, extending from the head to the anal 

 claspers ; this stripe is immediately below the spiracles, 

 which are testaceous-brown, surrounded by a very delicate 

 black ring ; the 2nd segment has a quadrate smoky black 

 dorsal patch, longitudinally intersected by a pale line ; it is 

 also bounded on both sides by a similar pale line ; the dorsal 

 area of the other segments is irrorated with smoky black,
