82 (April, 



11. (12). Elytra with a crust of broad scales which, practically, if not 



absolutely, obsciu*e the coiu-se of the striae; hind femora ^vith 

 a distinct shax'p tooth squamulatus, Gyll. 



12. (11). Elyti'a clothed with elongate scales ; liind femora simple. 



13. (20). Anteunse entirely pale. 



11'. (17). Punctures of the elytral stria; with extremely fine, hair-like, scales 

 about half as wide as those on the interstices, the coiu-se of the 

 strias, therefore, more evident. Elytra apparently twice as long 

 as wide, parallel-sided in the basal half. Femora usually dark. 



15. (16). Eostrmn strongly subiilate, especially in the lateral aspect. 3 with 

 a distinct sharp tooth near the basal third of the inner edge of 

 the front tibiae meliloti, Steph. 



10. (15). Eostrum not evidently subulate. S with the anterior tibise bisinuate 

 on the inner edge, but without a tooth tomentosus, Hei-bst. 



17. (14). Tlie scales arising- from the piuictures in the elytral strise not 

 evidently difPerent from the remainder, the course of the striae, 

 therefore, barely indicated. Elytra appearing less than twice as 

 long as wide. 



IS. (19). Scales of the elytral interstices elongate, but nearly twice as wide as 

 in junceus, the siirface, therefore, more closely covered. J : 

 anterior femora simple, anterior tibiae curved, the inner edge 

 bisinuate. ? .- greatest width of the thorax distinctly less than 

 that of the elytra. Leng-th, 2-2^ mm hxmafopus, Gyll. 



19. (18). Scales of the elytral interstices finer and more hair-like than in 



h.vmatopus, the siu-face, therefore, less closely covered. c? : 

 anterior femora with a fringe of hair-scales on the under-side, 

 from the base nearly to the apex, anterior tibiae strongly curved, 

 the inner edge excavate in the apical two-thirds. ? : greatest 

 width of the transversely sub-oi-bicular thorax very nearly equal 

 to that of the elytra jwnceits, Reiche. 



20. (13). Antennae blackish, with the scape and one or two joints of the 



funiculus pale. Femora black. Anterior tibiae in the <? with a 

 distinct tooth near the middle of the inner edge. 



21.(22). Tibiae rust-red, black at the base. Eostrum entirely black. In size, 

 form, and general appearance extremely like Miccotrogus 

 picirostris tibialis. Boh. 



22. (21). Tibise entirely rust-red. About half the bulk of medium-sized 



specimens of M. picirostris pusilhis, Germ. 



{pygmxus, Bris.). 



The above sequence of our species aims at a better expression of 

 tlieir affinities tlian that at present in use ; the obvious relationship of 

 meliloti and tomentosus becomes much obscured if we place lineatulus 

 and pince7i.s between them, and the latter belong to two different 

 sections of the genus. I have retained Gyllenhal's name squamulatus 

 for our insect, notwithstanding that fiavicollis, Steph., is used for it in 

 the European Catalogue, 1906 ; it is clearly hh-bli of G. K. Waterhouse
