PANSCOPUS (NOMIDUS) LONGUS, n. sp. 



Length, 7.6-8.3 mm; width, 3.1-3.8 mm. Relatively elongate; 

 rostrum with a fine median carina ; scape setose and scaly, nearly 

 reaching the middle of eye, seventh funicular segment a little longer 

 than broad, fourth to sixth segments not moniliform and about as 

 long as broad ; median pronotal sulcus distinct apically, interrupted 

 at middle, and very feeble or obsolescent basally ; elytra with alternate 

 intervals not or very little elevated, the setae suberect and finer than 

 usual. Derm blackish or piceous black, the scales dense, cinereous and 

 brown, forming variable and irregular markings which sometimes 

 are oblique, asymmetrical bars on the elytra. 



Rostrum stout, feebly arcuate, somewhat more than twice as long 

 as thick, about as long-as prothorax, a little longer in J* than in $, 

 upper surface broadly and shallowly discontinuous with front in pro- 

 file, subplanate or feebly convex except at the nearly scaleless apical 

 area which is. as usual, more or less impressed between the elevated 

 edges of the scrobes. nasal plate well defined, its apex sometimes 

 produced backward to the interantennal fovea ; above densely scaly 

 and with numerous suberect setae, the vestiture cinereous to fuscous 

 and not entirely covering the median carina, which extends from the 

 interantennal fovea to the fine interocular groove, the latter some- 

 times invisible ; scrobe gradually evanescent posteriorly but sometimes 

 nearly reaching the eye as a shallow, sparsely scaly sulcus. Prothorax 

 slightly wider than long in the J*, somewhat wider in the $, base 

 wider than apex (about 5 to 4), sides nearly straight and divergent 

 in about basal two-thirds, then converging and faintly constricted 

 apically ; pronotum rugose-tuberculate, the tubercles small and some- 

 times nearly covered with the dense scales, the summit of each tubercle 

 with a slender, slightly curved seta. Elytra elongate for this subgroup, 

 serial punctures moderately coarse, the setae slender, some of them 

 subacute at tip and appearing bristlelike (much as in aeqiialis and 

 squamifroiis) , sutural and third intervals slightly more prominent 

 than second, at least in apical half, the fourth interval similarly 

 convex in about apical half, the fifth, sixth, and seventh feebly and 

 subequally convex throughout. Setae, in general, more numerous on 

 alternate intervals, where they usually form a confused double or 

 partly triple row ; but where the convexity of adjacent intervals is 

 the same, the setae may be almost or quite as abundant on even as 

 on odd intervals. Beneath setose and densely scaly. A short length 

 of metepisternal suture visible opposite rear coxa. Hind tibia nearly 

 straight, the ventral edge hairy but without spines.
