stalk ; bristling hair rather capillareous ; in ? as usual, the indumentum of the nervures 

 is more hair-like throughout. Wing-markings chiefly dark hair-spots at the ends of 

 nervures, not extended into the fringe ; some dark hair, constituting either spots by the 

 sectorial and median forks, or a transverse fascia thereabouts, skirted externally in most 

 of the species with a narrow space of whitish-glossed outward spreading hair ; also the 

 ranks of bristling hair, whitish or opalescent, and in some instances a few additional dark 

 hair-spots interspersed ; fringes for some distance around the wing's apex light-glossed ; 

 dark elsewhere. Prothoracic air-tubes claviform, retained by the $, deciduous in the 

 aged. Antennae 16-jointed; $ 1st joint elongate claviform, subequal in length to the 

 next three joints combined ; 2nd joint densely squamate like the first, pyriform, or 

 inversely triangular and truncate like the butt-end of a gun-stock, and ciliated along the 

 outer edge with long acicular spinules contrasted in their light colour with the dark, 

 obtuse scales, which spinules tend to be fasciculate distally ; 3rd joint according to stand- 

 point shortly fusiform-ovoid, fusiform-urceolate, or somewhat truncate-biconical, subequal 

 in length to the fourth joint but with a shorter neck ; 4th — 14th joints lageniform with 

 ovoid, not quite symmetrical bulbs, each with a small sensory pore on the more pro- 

 tuberant side above the zone of hair, and with a single pair of long setiform articular 

 appendages (used perhaps for adjusting, from within, the whorl of hairs and for the 

 alignment of joints) inserted close together beside the pore and reflected apart with a 

 wide twisted curve towards the opposite side of the joint, slanting upwards; 15th joint 

 either sub-globular, ovoid, or oblong, closely approximated to the apiculate bulbous 

 16th joint. In antennte of $, long, dense, setaceous scales on one side of the 1st joint, 

 that reach as far as the whorl of hairs of the 4th joint, serve as a check to the obovoid 

 2nd joint, which has no tuft of acicular spinules ; 3rd joint asymmetrical, narrowly 

 amphoroid or vase-shape with sloping shoulder and short neck, or fusiform urceolate. 

 Protopodite in $ superior genital appendages stout, rounded externally ; exopodite 

 expanded at the articulation, unciform or falcate ; endopodite (?) a long, curved, subulate 

 spine. Inferior appendages short, little longer than the segment : tenacular spinules 

 numerous if distributed along the whole length of the forceps-limb, but if subapical fewer 

 and of graded lengths, the longest shorter than the limb. Ovipositor rostrate : sub- 

 genital plate in $ ending in a deep median sinus flanked by obtuse lobes. 



Type Panimerus hii'tus (Linn.) [notabilis Eaton), the only species previously described 

 out of 4 Palearctic species and 1 species from the Seychelles, sub manH. 



2. Panimerus scotti, sp. nov. $. (PI. 26, fig. 4.) 



Wings dark ashen-grey with fringes of the same colour from the base to the end of 

 72' on the costa, and to the hair-spot at the end of Cir on the opposite margin ; from 

 thence to the apex with somewhat cupreous-, or dull gold-glossed fringes, " shot " with 

 the aforesaid grey to a large extent ; and on the disk with black hair-spots set off with 

 white hairs, viz. : — (in addition to some ill-defined dark markings close to the wing-roots) 

 a dark rounded spot in the depression near the cross-vein Sc to i?' ; another at the end of 

 this depression, between /?' and the costa ; 7 spots marking endings of ranks of bristling 

 hair, set off with a few spreading white hairs externally (namely on the veins R^, R^, R*,
