176 GUY A K. MARSHALL. 



3 ; 5 and 6 sometimes bear a single transverse row of punctures ; 5-7 have the anterior 

 margin only shallowly sinuate and without a fringe of hairs, the sinuation not being 

 angulated laterally. The hind femora bear a dark patch in the middle, the tibiae 

 are all darker on the basal half, and the hind pair in the ^J have the uncus normal. 

 Genitalia of S '■ the median lobe (fig. 10, b) with the sides straight and very 

 gradually diverging from the base to beyond the middle, then gently rounded to the 

 apex, which is broadly truncate and a little wider than the base, the lateral angles 

 of which are obtuse, the greatest width at one-fourth from the apex ; the heavy 

 chitinisation is confined to the lateral margins and a slightly narrower transverse 

 band close to the apex, the rest being almost hyaline ; the median struts slender, 

 half as long again as the median lobe, gently sinuous throughout, distinctly 

 uniting with the sides of the lobe, and the connecting membrane between them 

 at the base hardly chitinised ; the uneverted sac extending inwards for only 

 one-fourth the length of the struts and without apparent asperities, the transfer- 

 apparatus rather large and with two awl-shaped processes ; the tegmen (fig. II, h) 

 with the proportionate lengths of the strut, ring and dorsal lobes approximately 

 as 3 : 2 : 4, the lobes being united only at their extreme base ; the spiculum as wide 

 as the tegminal strut and only shghtly widened at the apex, with one arm of the 

 basal fork about half as long as the other and forming an obtuse angle with it. 

 Genitalia of ? : the spermatheca as shown (fig. 7, c). 



Length, 4-4-6 mm. ; breadth, 2-2-75 mm.

Described from 12 specimens. 



Rhadinomerus subfasciatus, sp. nov. 



(^ 5- — Colour piceous black, with the apex of the rostrum and tarsi paler ; the 

 extreme base of the rostrum densely, the forehead less closely, clothed with cinnamon 

 scales ; the apical area of the prothorax with similar elongate scales, the remainder 

 not squamose, but with erect, compressed dark setae ; the elytra variegated with 

 more or less confluent spotsof cinnamon-coloured scaling, which usually form a broad, 

 broken transverse band behind the middle, the dark areas thinly clothed with much 

 smaller dark scales ; the lower surface without true scaling, but with sparse erect 

 pale setae. 



The other external characters as described for R. diversipes, except the following : 

 Sciitelliim of similar shape, but quite devoid of hairs. Elytra with the setae a little 

 longer and distinctly narrower ; the punctures not covered by a scale, this being 

 replaced by a very minute seta. Legs with the scales distinctly darker and smaller 

 on the basal than on the apical half of the tibiae ; the hind femora with a dark 

 median patch ; the uncus of the hind tibiae of the male normal. Abdomen with 

 ventrite 3 (1st visible) much more closely punctate, the punctures being three deep 

 behind the coxae ; ventrite 4 also bearing strong punctures, but much smaller and 

 more widely spaced than those on 3, and less numerous in the $ than in the ^. 



Genitalia of ^ : the median lobe (fig. 10, d) shaped just like that of R. mallott, 

 but the chitinised lateral areas more produced inwards in the middle, so that the 

 hyaHne median area is shaped like an hour-glass ; the median struts slender, three- 

 fourths longer than the lobe, strongly bisinuous in the basal third, distinctly uniting 

 with the sides of the lobe, and connected together by a lightly chitinised membrane 

 in the basal fifth ; the uneverted sac extending inwards for nearly half the length 

 of the struts, set with asperities in the terminal area, but without any obvious 

 transfer- apparatus or other chitinous structure; the tegmen (fig. 11, d,) with the
