TEGEOORANUS CEPHEIFORMIS. 341 



name must stand. The adult may be known from T, 

 latus by its smaller size, and the form of the lamellae. 



Colour very dark, dull-brown without any gloss. 



Texture rough, almost the whole dorsal surface cut 

 into deep, vermiform corrugations. 



Shape broad and rounded. 



Cephalotliorax pyramidal, or slightly pyriform. 

 Rostrum small, rounded, hut from the dorsal aspect the 

 rostrum is hidden by the lamelhe, which are very large 

 long blades more or less on edge, with a sinuated upper 

 outline ; they almost {or at their bases quite) join ante- 

 riorly, leaving a thin straight line between them, like a 

 knife-cut, instead of a considerable space which allows 

 the point of the rostrum to be seen, as is the case in 

 T. latus. The lamellae are lighter in colour than the 

 rest of the cephalothorax, and are clearly reticulated. 

 Lamellar hairs fine and curved, springing from small 

 indentations ; no cusps to the lamellee. No space for 

 any translamella. Pseudo-stigmata large, open , slightly 

 reniform, light in colour. Pseudo-stigmatic organs of 

 moderate length, clavate, but rather longer and more 

 bluntly ended than those of T. latus; somewhat re- 

 curved. Interlamellar hairs thick and near together. 

 Tectopedia large, clearly seen from the dorsal aspect. 

 Sternum fairly well marked. 



Legs rather long for the genus. The femora of the 

 first pair have slender peduncles to suit the deep clefts 

 in which they are inserted ; the other femora are pyri- 

 form. The genuals of the two front pairs are rather 

 longer than is usual in the genus ; tibiae slender and 

 clavate. The first pair of legs have the tactile hairs, 

 and there are a few other fine hairs arranged in a whorl 

 near the distal end of each other joint, except the tarsus 

 of each leg. Tarsi clothed with fine hairs in the usual 

 manner. 



Abdomen broad ; somewhat square in its posterior 

 outline ; truncated where it joins the cephalothorax, 

 from ivhich it is plainly divided. Notogaster distinctly 

 marked out into two regions, a central portion and a
