KEKMES QUERCUS. 143 



at the posterior extremity. Colour varying from 

 yellowish-brown to dark reddish-brown or crimson- 

 brown, with several more or less interrupted trans- 

 verse black bands, which are less distinct, narrowed, 

 and much more arched at the posterior extremity. 

 Antennae atrophied, articulations indistinct. Legs 

 atrophied, articulations indistinct. Dermis above 

 with numerous clear, gland-like spaces ; in the centre 

 of each is a highly chitinised, circular spinneret, with 

 a large inner connecting tube. Ventral derails with 

 many long, tubular spinnerets, and short, stiff hairs. 

 Anal orifice linear, placed about midway between the 

 anal and posterior extremities. Rostrum directed 

 forwards and placed near the end of the slender, 

 attenuated anterior extremity of the insect ; mentum 

 Inarticulate, rather long, and a little wider at the base 

 than at the centre. Spiracles large ; parastigmatic 

 glands numerous. 



Long, 3-5 mm. ; wide, 2'50-4 mm. 



Mr. Greo. B. King (1. c.) describes the salient 

 characters of the young female larvae as follows : 

 " Caudal tubercles small, each with one long bristle 

 ISOjulong, one spine-like hair 40 /n long, one short 

 spine 16 ju long, and one glandiform spine. A little 

 distance above the anal orifice are two ordinary spines 

 16 /a long. Antennae six- jointed ; formula 6 (1, 2, 3, 5), 

 4, or 6, 1 (2, 3), 5, 4. All the joints have short, thin 

 hairs. Middle legs short, stout." 



Larva (extracted from the body of the parent, and 

 therefore probably immature) short ovate. Antennae 

 of six joints ; the first joint is much the widest ; the 

 second, third, fourth, and fifth are the shortest ; each 

 joint is furnished with a few fine slender hairs and a 

 pair of minute, laterally placed spines; apical joint 

 much the longest, bearing several long hairs and two 

 or three shorter curved ones ; formula 6 (1, 2, 3, 4, 5). 

 Legs much longer than the antennae, and very broad 

 at the tibio-tarsal joint ; claw very long ; digitules 

 simple. Anal lobes minute, each with a single
