PKVTOSUS, Curtis. 

 This genus contains three or four European species, which are found 

 under refuse, &c., on the sea-shore, usually below high-water mark ; Mul- 

 sant and Key divide them into two genera on certain characters of the 

 nietasternum and the greater or less length of the elytra: it seems a 

 matter of much uncertainty whether we have both species of the sub- 

 genus Acfusus in Ih-itain ; they are, however, so closely connected, that it 

 seems rather doubtful whether they are really separate species. 



The larva of Pkj/tosus niffriventris is described by Fauvel, Ann. Fr. 1862 p 84 

 pi. 2, fig. 14: it is 2 mm. in length, a little widened behind, rather convex.ofa 

 whitish colour with the head slightly reddish ; in general shape it resembles very 

 much the perfect insect ; the head is large and broad, and the antennie very short • 

 the prothorax is larger and broader than the meso- and meta-thorax ; the abdominal 

 segments are very transverse, almost rectangular, the first being the narrowest part 

 of the body, so that the insect appears strangulate in the middle ; the ninth se^rnienfc 

 IS much narrower than the eighth, and apparently bears no anal appendage or cerci • 

 the legs are rather long and stout. ' 



This larva is found under stones in damp places near sand-hills, and appears to feed 

 on PoduridiB. 



Upper surface dull black ; elytra longer th.an thorax .... 1^. spihifeu, Curt 

 Upper surface chiefly reddish testaceous; elytra very short, 



much shorter than thorax p_ balticus Kr 



P. spinifer, Curt, {semilunaris, Rey). Depressed, linear, and parallel, 

 finely pubescent, dull black, with the elytra more or less broadly reddish 

 towards apex ; head about as broad as thorax, antennse short, somewhat 

 moniliform, with joints 4-10 gradually thicker, strongly transverse • 

 thorax as long as broad, narrowed towards base where it is narrower than 

 elytra, very obsoletely, thickly, and finely punctured, and usually 

 broadly impressed longitudinally; elytra longer than thorax, finely 

 punctured ; hind body a little narrowed at base and slightly widened 

 behind, much more shining than the front parts with the apex often 

 reddish or yellowish, finely punctured, a little more finely on sixth 

 segment, segments 2-5 plainly impressed longitudinally; legs testaceous 

 with femora dusky. L. 2i mm. ' 



Male with the sixth segment of hind body sinuate on its apical 



margm.
