heds ; local but apparcuMy not uncommon ; London district, very generally dis- 

 tributed ; Tonbridge ; The Holt, Farnliam j Needwood Forest; Knowle, near 

 Birmingham; Lincoln; Liverpool; Manchester; Scotlnnd, local, Sol way/, Forth, Tay,

O, exig-ua, Er. {OxyporJa (Podoa-ya) e.rif/ua, Mtils. et Eey). A 

 small and obscure species, black, rather shining, with the elytra and 

 apex of hind body brownish • head rather large, finely but distinctly 

 punctured ; antennae yellowish, or broAvnish with the first joint at least 

 testaceous, third joint a little shorter than second, 6-10 transverse, 

 eleventh rather broad, as long as the two preceding together, acuminate at 

 apex"; thorax broader than long, as broad behind as elytra, finely and 

 thickly punctured ; elytra slightly longer than thorax, plainly transverse, 

 rather distinctly and somewhat riigosely punctured ; hind body plainly 

 narrowed and setose towards apex, thickly and plainly punctured 

 towards base, sparingly punctured and smooth and shining behind ; legs 

 testaceous, femora more or less pitchy, posterior tarsi with the first 

 joint equal to the two fallowing together. L. 1| mm. 



Male with ventral plate of seventh segment of hind body a little 

 prolonged and obtusely angled in middle of apical margin. 



The transverse elytra, small size, and the sculpture of the hind body 

 will at once separate this species from all the preceding. 



In sandpits, &c., in moss and under vegetable refuse; rare; Shirley; Wimbledon; 

 Deal. Scotland, Tay district, Bannoch. 



O. mutata, Sharp (n'paria, Fairm. nee Thorns., ruguJosa, Kr. ?, 

 O.ri/poda (Podoxya) riparia, Muls. et Eey). This is one of the most 

 distinct of all our species, and may be easily known by its very strong 

 punctuation (almost "engine-turned," as Mr. Eye calls it, Ent. Ann. 

 1872, p. 52), and the small more or less distinct projection on the basal 

 margin of thorax ; the colour is ferruginous with the head and inter- 

 mediate segments of hind body darker ; the antennae are distinctly 

 thickened, testaceous, darker towards apex, or obecurel}^ ferruginous with 

 base lighter, third joint plainly shorter than second, 6-10 strongly 

 transverse ; the elytra are a little longer than the thorax, and are more 

 strongly and rugosely sculptured; the hind body is distinctly and almost 

 uniformly punctured ; the punctuation however of the apical segment is 

 slightly finer; legs testaceous, posterior tarsi with the first joint ecjual to 

 the two following together. L. 2-2^ mm. 



Sandpits and banks of streams, under dead leaves, &c. ; early summer; very rare, 

 Shirley near Croydon; Coombe Wood; Colney Hatch. 



The species is somewhat of the form of 0. exoleta, but differs in its 

 smaller size, coarser punctuation, and somewhat diH'erently shaped 

 antennae ; in the single specimen I have seen the hind body is almost 

 parallel-sided, but in fresh specimens it is said to be plainly narrowed 

 behind.
