which is nearly median, they carry on the ventral side a 

 number of hairs. Labrum with well-developed dense tufts 

 of hairs. Maxilla? conical as in prccedinj? species, but with- 

 out hair at its extremity; the palpi with rather lartrer spines 

 on the internal side. Mentum without distinct indentation. 



Anterior border of prothoracic sternum with moderately 

 lonjr black bristles pointinj; forward and not reachinjj; be- 

 yond the head; they are disposed according to the following: 

 order, four of them making a tuft on each side: 1.1.1.4.1.- 

 1.4.1.1.1. The two outer ones on each side are only half the 

 size of the others. The armature of spines on the sternum 

 of abdominal sejrments 5-7 are as in the preceding species 

 as to number and disposition; the spines, however, are 

 relatively longer, and between the two groups there is no 

 chitinoiis longitudinal small plate. 



The sternal basal plates of the caudal appendages with 

 two groups of three moderately long bristles; the caudal 

 appendage, which is testaceous and I'elatively small, carries 

 six long black bristles about twice as long as the appendage 

 itself. 



Spiracular plates according to figure 7C; the spiracles 

 themselves are i-oundish; the V-shaped structure between 

 them is provided with two groups of three small 

 tufts of curved hair as in preceding species. The 

 bases of the lateral plates are connected with each other 

 by a chitinous formation; their inferior comb is composed 

 of a row of very small spiniiles which end in a relatively 

 large trilid spine.

Len'jth of full-grown larva (ll min. Its colour is of a 

 dirty yellowish, the dorsum darker on account of the long 

 hairs of the abdomen; head testaceous with a black anterior 

 and posterior edge above. Antenna.' and palpi black; labrum 

 with the usual dense, well-developed tufts of hair; mandibles 

 as usual, maxilbe also, pointed, with only a few hairs at the 

 tip. Anlenmr without hairs or bristles, only with the short 

 triangular spinules. Mentum without distinct indentation. 



No conspicuous bristles on the anterior edge of the pro- 

 thoracic sternum; the first pair of abdominal prolegs more 

 (level' ped than the second; armature of hooks present only 

 on the .'ilh and 6th abdominal segments, and composed of 

 two adjacent groups of spines in two juxtaposed rows, the 

 inferii r one being formed of six straight thin spines, the
