TRAGARDH, TWO MYRIOPODOPHILOUS ANTENNOPHORIN.B. 3 



The dorsal side is protectecl by a shield, which covers almost 

 the whole surface and only in the two last thirds of the body 

 leaves unprotected a narrow strip of white, weak, finely con- 

 centrically striated skin which is surrounded by a narrow mar- 

 ginal plate. 



The dorsal shield bears very minute hairs. The marginal 

 plate is discernible from the level of coxa II and is flattened, 

 with a sharp knifehke edge. It is provided with bristles 

 which are of two kinds viz., strong, sharply pointed spines (s) and 

 more slender bristles (b) which are twice as long as the others. 

 They are with the exception of three very short curved perpen- 

 diciilar spines, which are situated one behind the other on the 

 ventral side of the plate furthest anteriorly, situated on the 

 dorsal side of the plate above the knifehke edge and are radia- 

 ting. They are gener ally arranged as foUows: 2 b,M s, 1 b, 5 s, 

 1 b, 6 s, 1 b, 7 s, 1 b, 8 s, 1 b, 11 s, the 11 spines occupying 

 the central space between the posterior bristles. The longer 

 bristles always amount to 14, the spines are subject to a 

 variation of from 52 to 72. 



Ventral side (Fig. 2, Pl. I). 



Tritostermim of the usual shape, rather long, posteriorly 

 only a little wider than anteriorly; the feathered slips nearly 

 twice as long as the tritosternum. 



The jugidar shield single, very narrow, laterally gradually 

 widening and extending beyond the anteriör angles of the 

 sternal shield, provided Avith two pairs of hairs, of which one, 

 almost perpendicular is situated on both sides of the tritos- 

 ternum. 



The sternal, inetasternal, ventral, anal and pedal shields are 

 fused together into one shield, which covers the hole space be- 

 tween the legs II, III and IV and the whole median part of 

 the belly except a narrow band, which separates it from the 

 marginal plate. The sternal portion of it is very finely punc- 

 tured, provided with three pairs of hairs and has a pair of 

 lines parallel to the lateral edges, which show where it is fused 

 together mth the pedal-shields II. Inside these lines are a 

 pair of groups of 8 — 10 very small perpendicular bristles. 



The remaining part of the shield is provided with three 

 pairs of hairs, directed centripetally, is narrowest between legs 



^ the first one is only a little longer than the spines.
