lapping each otlicr at the tips (J in cixt). Antennae four-jointed (K 

 in cut) . Each lobe of the tail with two bristles, and the other larval 

 segments wdth one on each side, excepting the segment immediately 

 behind Ihe head, which has on either side two bristles or more. 



This description was taken from a larva still of such minute size 

 as to be barely perceptible to the naked eye, and (presumably) not 

 more than twelve hours old. 



In the above recorded investigations, a few points struck me par- 

 ticularly : the first being the coincidence between the duration of the 

 life of the larvas and that of the flowering stems on w-hich they were 

 placed. Next, the apparently enforced dropping down of the larva 

 when its time of feeding was complete ; from the size of the plants 

 compared with that of the insect, the journey would have been one of 

 enormous length, and without provision, by the way, the hardened 

 stem not affording the little collections of sap in which the larva? 

 appeared to delight. Another point was the position of the larva 

 in the egg. From the great relative size of the portion (about 

 the third or fourth segment) in the egg which, until almost complete 

 development, represented the extremity opposite to the head, I 

 think that until almost the time of hatching the larva lay bent on 

 itself, and then suddenly straightened itself, throwing the head into 

 the natural position. The fourth point Avas the colour (in the egg, 

 and from a few hours after hatching, the larva showed patches of pur- 

 ple colour) as it stepjied from the egg, and for a few hours these p.arts, 

 as the insect generally was quite white. Possibly this is well known 

 in other cases, but I do not myself understand the reason of it.

Closely allied to Bufcla, but separated by the following characters. 

 Antennre with the basal joint thick, the second smaller, the third to 

 seventh gradually decreasing in size, the eighth to tenth forming an 

 elongate club. Clypeus separated from the head by an impressed line. 

 Thorax with a broad rounded lobe over the scutellum ; the lobe not 

 emarginate. The large claw to all the tarsi bifid at the apex.
