104 i^'^y. 



The aecleaj^-us is remarkable by the long upper lip of the median 

 orifice, which is apparently alway elevated l)y a trigger-like structure. 

 The bridge of the tegmen is moderately broad, the strut is about as 

 long as the diameter of the tegmen ; the tegminal appendages are 

 quite oljsolete. The space enclosed by the callipers is rather larger, 

 and the two are a little prolonged anteriorly, and thei'e nearly parallel 

 and contiguous. The species occurs in the southern part of the 

 Kingdom in several localities, and occasionally in some numbers, but 

 it is far from common. 



2. — Bagous daudirans Boh. 



Variable in size, from 2j-3 mm. long. The elytra are rather 

 broad, and stand out at the shoulders very much beyond the thorax, 

 which is about as long as broad, and is somewhat coarsely rugose. 

 The coloration is markedly maculate, and has a very slight olivaceous 

 tinge in fresh specimens ; a pale mark beyond the middle is usually 

 conspicuous. The antennae are variable in colour, usually largely 

 yellow, with a very broad dark club ; the dark colour sometimes ex- 

 tends nearly to the base, but this always remains yellow. The tarsi 

 are of moderate length, sometimes yellow, generally a good deal in- 

 fuseate ; the second joint of the posterior pair about as long as it is 

 broad. 



The aedeagus is characteristic and invariable (when mature). I 

 have examined it in about 20 specimens. The callipers are very 

 slender at the tips, convergent and contiguous there, and inclose a 

 rather large area. The apical portion of the median lobe is broad ; 

 the actual apex is broad, almost truncate, with a very minute acumen 

 on each side. The bridge formed at the base of the margin of the 

 upper lip of the median orifice is very marked, rather deeply sinuate 

 on each side, and with a short longitudinal elevation in the middle. 

 The tegmen forms a slender ring, with a pair of delicate, slender 

 appendages in the middle, joined at the base ; the strut is slender, 

 rather longer than the diameter of the tegmen. 



This species seems to be but little known in collections, but it is 

 abundant at Brockenhi;rst in the spring and autumn and may some- 

 times be found in hundreds ; it frequents the muddy margins of small 

 stagnant pools. It has also been fomid by Mr. Tomlin at Tresco in 

 the Scilly Islands, and Mr. Bed well has a single example from the New 

 Forest; Campbeltown, one specimen, November, 1894 (/. /. Walker); 

 Edenhall, Cumberland, 13. v. '06 (Britten, one specimen).
