ME. E. I. POCOCK ON THE 



anal valves very pale olive-green ; antennae, legs, and region of 

 labrum ferruginous. 



Each somite marked below by a sulcus, which becomes fainter 

 and finally disappears towards the dorsum. Foramen repugna- 

 torium situated immediately behind this sulcus, above the middle 

 of the somite ; a small area surrounding the foramen black and 

 smooth. Each somite thickly and finely punctured ; lateral 

 inferior portion as high as the foramen, striated. Posterior 

 portion of each somite more strongly striated, less strongly 

 punctured. 



Eirst dorsal plate laterally scarcely overlapping and not ex- 

 tending lower than the second ; anterior border nearly straight, 

 forming with the posterior border a blunt rounded angle ; antero- 

 inferior margin with a strongly marked groove. 



Lower portion of clypeus with strongly marked central sulcus ; 

 upper portion of sulcus very faintly indicated. Labral region 

 marked with two impressions on each side of the middle line. 



Posterior somite produced into a stout, blunt process, which 

 projects slightly beyond the margins of the anal valves. Margins 

 of anal valves strongly thickened and compressed. Sub-anal plate 

 posteriorly angulate. 



A single female specimen from King Island. 



The specimen described by Dr. Karsch, which is also a female, 

 was from Siam. The male appears to be unknown. 



Spieobolus pheanus, Karsch, t. c. p. 65. (Plate XXV. 

 figs. 6-6 e.) 



Length 52 mm. Number of somites 55. 



Posterior portion of each somite testaceous, anterior portion 

 brownish grey. Legs, antenna), and lower portion of clypeus 

 testaceous. 



Each somite marked with circular sulcus into an anterior and 

 a posterior portion ; very finely punctured ; laterally and infe- 

 riorly longitudinally striated. Dorsally the central portion is 

 furnished with numerous linear elevations, which, running 

 parallel to the margins of the somite, and anastomosing in every 

 direction, give rise to a reticulated pattern ; the interstices 

 formed by the intersection of these elevations posteriorly break 

 up into more or lose elliptical areas, and disappear on the hinder 

 portion of the somite. Foramen repugnatorium inconspicuous, 

 nituated upon the middle portion of the somite. Somites not 

 provided with scobina.
