94. Trigoniulus megaloproctus , sp. n. PI. XXII, fig. 28. 



Flores: Maumerie. 



Colour; somites pale in front, black in the middle, ferruginous 

 posteriorly; head, first tergite, anal valves and tergite fuscous, an- 

 tennae fusco-annulate , legs ochraceous. 



Head smooth, marked throughout by a faint vertical sulcus, which 

 is stronger below; four pores on the labrum. Antennae short, only 

 about as long as the head. Eyes widely separated, the distance be- 

 tween them equal to about twice a diameter. 



First tergite with its posterior border laterally nearly straight, the 

 corresponding portion of the anterior border very lightly concave and 

 defined by a distinct sulcus, the angle acute, rounded, and extending 

 almost as low as the inferior extension of the second. The rest of 

 the somites longitudinally striate about half way up to the pore; the 

 upper surface finely striolate, striolee running obliquely backwards 

 and outwards from the middle dorsal line and more or less breaking 

 up into punctulation posteriorly ; only the extreme hind border smooth ; 

 the transverse sulcus visible laterally as high as the pore; obsolete 

 above. The pores just above the middle of the side, immediately in 

 front of the sulcus, the anterior one a little the lowest. Anal somite 

 rugulose, large, its upper surface convex from behind forwards, with 

 a strong constriction before the angle which covers the apex of the 

 valves without extending beyond them; valves convex with margins 

 scarcely compressed ; sternite not angled posteriorly , its hinder mar- 

 gin straight. 



Legs with a single seta below each segment. 



cf With tarsi padded. Copulatory feet with the anterior piece long, 

 with two long upper arms, the angle extending inferiorly as low as 

 the inferior angle of the anterior lateral piece, beneath which the 

 posterior lateral projects. 



Number of somites about 49. 



Length up to about 55 mm.; width about 5. 



This species is perhaps allied to decoratus of Karsch from Viti 

 Levu ; but the last it described as having the somites deeply segmented.
