The proper uaine of this species is still doubtful. B. daudleans 

 and mundanns are considered to be synonyms, and if this be really the 

 case, the name mundamis should be used, as it comes first in the 

 book where both were originally described. Brisout mentions several 

 varieties, most of which are probably distinct species. One of these, 

 " fritillain Walt(ni," was, I believe, never published, so that we are 

 spared the necessity of determining it. 



3. — Batons tondini, sp. n. 



B. claudirantis persimilis. Minor, niger, griseo-varieijatiis, antennis (clava ex- 

 cepta) testaceis, tibiis fusco-testaceis vel iiigris ; tarsis gracilihus, fere elongatis. 

 Long., 2 J mm. 



This is extremely similar to the preceding species {B. claudicans), 

 but appears to be smaller, has no olivaceous tint, the elytra are not so 

 broad, so do not stand out so much from the thorax, and the sculpture 

 of the thorax is a little finer. The tarsi are rather longer and more 

 slender, the second joint of the posterior being not so broad as it is 

 long. The aedeagus differs markedly, having an acuminate slender 

 extremity, and the bridge of the upper lip of the median orifice more 

 distant from the apex. The tegmen is remarkably slender and delicate, 

 with very long slender strut, and i^iperior appendages. 



Thi-ee examples were found by Mr. Tomlin in the Eoniney Marshes 

 many years ago ; and there is a specimen in the Chitty collection at 

 Oxford, labelled " New Fst. Ju. 1, 1893." 



4. — Bagovs arduus, sp. n. 

 B. claiulicantis 2)ersimilis, tarsis elongatis facile distinguendus. Long. 3 mm. 



Although I have seen only a few specimens of this insect, there is 

 no doubt as to its being a distinct species, the aedeagus being quite 

 adequately diagnostic. It is rather broad and shaped much as in 

 claudicans, but the apex is broad, truncate, feebly bisinuate, and the 

 upper lip of the orifice is more distant from the apex. The tegmen and 

 basal portions of the organ seem to be much the same as in claudicans. 



I do not attempt to sketch the minor details of the species, the 

 material being so scanty ; but independent of the aedeagus the k>nger 

 tarsi readily differentiate B. ardunt<. 



My unique specimen was given to nie many years ago as "frit " 

 (= claudicans). I cannot decipher the writing on the card, but the 

 insect is probably from the London- district. In the Champion collection
