Mr. W. F. K^nhJ—^''otes on Blattida3. 409 



This fine species is evidently closely allied to, if not iden- 

 tical with, /S. ternateyisis, Brann. ; but as that species was 

 described from another island, apparently from damaged 

 specimens, and too briefly to admit of a proper comparison, 

 I have decided to give a full description, and to treat it as 

 provisionally distinct. 



Centre of pronotum projecting over the head in a sort of 

 hood, excavated in front, and tuberculate on the sides ; the 

 sides of the pronotum produced into large curving horns, 

 with a strong blunt tooth at the base above ; front femora 

 unarmed, the penultimate segment of the abdomen slightly, 

 and the last strongly dentated at the sides ; terminal plate 

 broad, rounded, and dentated, with a very large tooth beyond 

 the cerci. Tegmina laterally rudimentary, as long as the 

 metauotum. 



Type Panesthia forceps, Saussure. 



Hah. Pondicherry {Saiiss.), Nilgiris. 



Allied to Sahjanea, Sauss., to which Saussure subsequently 

 referred his Panesthia forceps ; but differing in the remarkable 

 structure of the pronotum, which is not unlike that found 

 in some Dynastidie among the Coleoptera, and by the rudi- 

 mentary tegmina. 



Saussure describes his insect as a female^ but of six 

 specimens now before me, one only, a male, agrees with 

 his figure ; in the others, which are females, the horns are 

 shorter, and the concavity in front of the pronotum is shallower 

 and more rounded. I may note that the antennae are black 

 for three fourths of their length, and then orange, shading 

 into brown at the tip. 



Genus DiCELLONOTUS, Butl. 



To this genus I refer the types D. lucanoides and D. morsus^ 

 Butl., Panesthia monstruosa, Wood- Mason, and P. Panteli, 

 Bol., and two new species. 



DiceUonotus Icevi's. 



Long. corp. 50 millim. ; lat. 22 millim. 



Female. — Uniform black above ; the labrum, the joints of 

 the palpi, and the pulvilli ferruginous; the under surface of 

 the antennae, the greater part of the legs and of the under 

 surface of the body^ and the cerci more or less of a dark 

 chestnut-red ; terminal plate of abdomen black above and
