SEINOSUKE UCIIIDA: 



of front; eye prominent, slightly emarginate, with a distinct, quadran- 

 gular, black fleck ; ocular fringe covered by the anterior margin of 

 temple, comb-like, triangular in shape, composed of numerous short 

 spines. Palpi long, projecting by the whole length of the terminal 

 segment. Antennae (Fig. 2) prominent, projecting ; the first segment 

 short, with a few prickles ; the second , 



expanded ; margins somewhat angui. ited in front and behind, each 

 bearing six hairs and a few prickles, both on margin and on dorsum ; 

 occipital margin slightly concave, with four hairs. Ground colour of 

 head yellowish white, more deeply yellowish in front ; ocular blotches 

 and a spot near the margin in front of each palpus reddish brown ; 

 occipital margin narrowly edged with yellowish brown. On the ven- 

 tral aspect of head, on each side of the median line, between mouth 

 parts and the occipital margin are seven hairs which gradually become 

 longer posteriorly. 



Prothorax small, with produced lateral angles, each bearing a 

 hair and t.vo spines; anterior lateral margins convex, each with two 

 prickles ; transverse chitin bar pale but distinct, with obliquely long- 

 itudinal bars at its ends ; posterior lateral margins bare, slightly 

 convex ; posterior margin straight. On the dorsal surface of prothorax 

 a row of eight hairs along the posterior margin. Metathorax triangular 

 in outline, with very slight lateral emarginations and an indistinct 

 suturai line between meso-and metathoracic segments ; anterior lateral 

 margins straight, diverging posteriorly, with numerous short hairs ; 

 posterior lateral angles obtuse, each with two long hairs in the near 

 neighbourhood ; posterior margin truncate with eight submarginal hairs. 

 On the dorsal surface of metathorax numerous weak hairs arranged 



segment large, broadend toward the apical 

 side, bearing three short hairs ; the third 

 segment the smallest, cup-shaped ; the fourth 

 the largest, somewhat globular, bearing 

 numerous sensory hairs on tip. Temples
