Note. — In the species pimc/icoZ^zs, which I have assigned to Geoderces, 

 the scrobes are slightly more open when viewed from above, and as this 

 is a much smaller species than those forming the types of the genus, it 

 may possibly necessitate the creation of a subgenus. 



PAl^ORMUS n. gen. (Otiorhynchini). 



Body oval; elytra inflated; similar in form to Trigonoscuta. Head 

 hemispherical; beak much narrower and longer than the head; sides 

 parallel; alae slightly dilated; surface not broadly impressed at base, 

 but having a fine arcuate groove between the anterior extremities of 

 the eyes, finely grooved along the middle, the groove crossing the 

 transverse basal channel and extending slightly onto the front. Eyes 

 oval, distant from the prothorax, rather small, coarsely granulated and 

 prominent. Scrobes lateral, rather narrow, deep anteriorly, gradually 

 evanescent, feebly arcuate, directed upon and nearly attaining the eyes. 

 Antennee subapical, shining, setose; scape slender, verj^ grcidually and 

 feebly clavate toward apex, fully as long as the funicle, extending 

 beyond the eye, but not attaining the prothorax; funicle seven- jointed, 

 basal joint nearly as long as the next two together, second longer than 

 the third, outer joints moniliform and short, seventh wider, transversely 

 oval; club rather short and robust, ovoidal, pointed. Prothorax with- 

 out trace of ocular lobes or fimbriae, broadly infiated. Scutellum minute, 

 indistinct. Elytra inflated, very feebly inflexed at the sides. Abdomen 

 flat; first suture arcuate in the middle; second segment as long as the 

 next two combined. Legs moderate; femora robust; tibiae and tarsi 

 slender; anterior tibiae straight, slightly produced outward and dilated 

 at apex, not denticulate within; posterior tibiae with outer edge at apex 

 broadly double; inner face or cotyloid surface slightly oblique, plane, 

 with a few scattered scales; inner terminal spur rather large and
