110 Traiisarfioiis. 



Scape straight, inserted immediately before the middle, gradually in- 

 crassate, attaining the centre of the eye ; 2nd joint of funiculus as long as 

 the 1st, 3-5 rather broader than long ; club indistinctly articulated and 

 hardly broader than the preceding joint, but appearing more ovate when 

 examined in another way. Legs normal, penultimate tarsal joint slightly 

 dilated but not lobed. 



Female. — ^Rostrum little more than half as thick as that of the male, 

 cylindric, shining, and much more finely punctate. Scape more slender, 

 implanted behind the middle. Thorax more gradually narrowed anteriorly 

 and less constricted in front. The vestiture less obvious. 



The pubescence causes this species to seem strange in Pentarthrum ; 

 still, I fail to detect any good differentiating characters. 



Length (rostrum inclusive), 4 mm. ; breadth, 1 mm.

96. Agastegnus ornatus sp. nov. 



Subdepressed, elongate, nitid ; sparingly clothed with slender yellowisli 

 pubescence ; elytra testaceous, with an irregular broad pitchy-brown fascia 

 on each, extending obliquely forwards from the hind thigh to before the 

 middle but not quite reaching the suture, and a smaller dark spot behind 

 but distant from the side ; the head, front of thorax, and the club somewhat 

 piceous ; the rest of the body, legs, and antennae bright chestnut-red. 



Rostrum rather shorter than thorax, a little narrowed towards the base, 

 moderately finely punctate. Head narrowed anteriorly, more distinctly 

 and closely punctured than the rostrum, the occiput smooth and shining. 

 Eyes subrotundate, slightly prominent. Thorax abruptly constricted near 

 the apex, about as long as broad, the sides behind the constriction strongly 

 rounded ; disc rather flat, with a smooth linear space along the middle 

 terminating in a well-marked basal fovea, its punctation distinct, closer 

 at the sides, its apex nearly smooth. Scutellum smooth. Elytra rather 

 broader than thorax at the base, nearly parallel-sided, gradually narrowed 

 posteriorly ; they are distinctly striate ; the punctation of the striae, how- 

 ever, is not sharply defined, and appears crenate on some parts ; interstices 

 finely punctured and rugose, the 3rd and 5th somewhat elevated, the former 

 near the extremity, the latter behind the dark median fasciae. 



Underside shining, piceous, with some slender grey setae, the pro- 

 sternum with distinct yellow ones, and rather coarsely punctate. The 

 metasternum elongate, more finely punctured on the middle than at the 

 sides ; behind each of the intermediate coxae there is a well-marked fovea, 

 and along the hinder half a median groove. Basal ventral segment nearly 

 twice as long as the 2nd, strongly rounded between the coxae, broadly 

 impressed in the middle, distantly and distinctly punctured ; 3rd and 4t]i 

 short, with deep sutures ; 5th with a very obvious median fovea. Anterioi' 

 coxae nearly as far apart as the intermediate pair. 



Legs moderately elongate ; tibiae with well-developed apical hooks ; 

 tarsi elongate, their 3rd joint slightly dilated, excavate above, but not 

 bilobed. Antennae medially inserted, 2nd joint of the funiculus as long as 

 the 1st, joints 3-5 transverse ; club oblong-oval, densely pubescent, obso- 

 letcly articulated.
