SANJI HOZAWA : 



posterior margin slightly sinuate. Dorsal surface of pronotum slightly- 

 arched, finely punctured, with three pairs of longitudinal ridges, viz., 

 a median pair formed of the longest ridges and two more pairs formed 

 of antero-lateral and postero lateral ridges on both sides of the median 

 pair (fig. 8). 



Prosternum. — With a moderately broad median ridge, anterior 

 margin concave, posterior margin also concave but with a short pointed 

 process in the middle (fig. 9). 



Elytra. — The elytra in situ (fig. 1), about 2\ times as long as 

 broad, distinctly broader than pronotum ; base gently arcuate and 

 notched in the middle ; lateral edges quite or nearly parallel in basal 

 I of their length and then gently curving towards each other before 

 they meet at the apex, giving to this part of the elytra an inverted 

 dome-like outline and showing in this part only an obscure constriction- 

 like depression of surface. Costa numbers ten on each side (fig. 11). 

 The ist costa forming the inner margin of each elytron is long ; the 

 2nd also long, almost reaching to apex of elytron ; the 3rd shorter 

 than the 2nd but longer than the 4th, which is the shortest of all ; 

 the 5th longer than the 6th but shorter than the 7th, which is nearly 

 as long as the 2nd ; the gth shorter than the 8th ; the ioth long and 

 forming the outer margin of elytron. Each inter-costal area is beset 

 with a row of minute quadrate punctures with rounded corners. 



Abdomen. — Dorsal integument soft, not so strongly chitinized as the 

 ventral integument, brownish yellow in colour. Ventral surface rather 

 flat, showing five segments, of which the 4th is the shortest (fig. 10). 



Legs. — Compressed. First and second legs are of about the same 

 length and structure; tibia shorter and narrower than femur, with very 

 fine lateral and three large terminal spines ; tarsus short, thick, dimi- 

 nishing in thickness towards the extremity, 5-jointed ; the proximal 

 four joints short ; the 5th joint nearly as long as the preceding two 

 joints combined, with two incurved claws (figs. 12, 13). Third leg 

 much longer than the first or the second ; tibia with two terminal
