intercoxal process rounded and narrower than the coxa ; 

 sejiment 1 (beliiud the coxa) longer than 2, and 2 longer 

 than 3, the hind margin of segment 1 arcuate. Legs short 

 and ratiier stout; femora moderately clavate and simple; 

 tibire unguiculate, the corbels of the hind ])air oblique, ])are, 

 and open, but with the apical edge slightly bent inwards ; 

 claws connate. 



In the (^ the fifth ventral segment is shorter and flat, in 

 the ? it is a little longer and slightly convex. 



Genotype, Sirophosomus kirschi, Faust (Knt. Naclir. xi. 

 1885, p. 88). 



Pomphus denticollis, sp. n. f PI. I, fig. 3.) 



Black, with srey or sandy scaling, the pronotura with a 

 very l)road median brown stripe, and the elytra with very 

 variable dark hrown markings, which arc sometimes almost 

 entirely obliterated. 



Head almost flat on the forehead and set with stout erect 

 setae, the integument quite hidden by the scaling. Rostrum 

 Avith the sides strongly convergent from tlie eyes to heyond 

 the middle, thence nearly parallel ; upper surface with two 

 deep sulci strongly diverging from the centre of the base as 

 far as the middle of the disk, the lateral areas outside them 

 l)eing shallowly impressed ; the central carina is prominent 

 where it meets the epistome, but diminishes behind and 

 disa])pears about the middle ; the clothing as on the forehead, 

 Antennos with the apical lialf of the scape squamose ; funicle 

 with joints 3, 4, and 6 subeqnal arid slightly longer than 

 Ijroad, 5 a little shorter, 7 as long as 6 but distinctly broader. 

 Prothoj'a.c twice and a half as broad as long, the base (when 

 seen clear of the elytra) not l)roader than the apex ; the sides, 

 as seen from above, distinctly denticulate, there being a 

 specially marked projection close to the base, and the aj)ical 

 angles prominent : apical margin strongly reflexed down the 

 sides, the ridge thus formed ceasing abruptly on a line 

 with the outer edge of the coxa; upper surface strongly 

 convex transversely, closely set with rather indefinite 

 granules (tlie rugose sculpturing being hidden by the 

 scaling), and with a central furrow that reaches neither the 

 base nor the aj)ex ; the longitudinal outline only slightly 

 curved, the-apex being only a little lower than the base. 

 Eh/tra with the sides strongly rounded, broadest about the 

 middle, scarcely striate, but with rather irregular rows of 

 punctures, whicli are conspicuous through the scaling and 

 often duplicated ; the intervals broad, finely aciculate
