 an inhabitant of clung, altiiough, like many dung-feeders, it has been 

 taken in moss, &c. 



TROGOLINUS, Sharp. 



Trogophloeus, cmct. subg. nov. TrogoUtvus, Sharp (Ent. Mo. Mag. 

 xxxvi. (2 Ser. xi.), 1900, 281). Dr. Sharp characterises this sub- 

 genus, which appears to deserve generic rank, as follows : "Antennae 

 with none of the joints transverse ; head strongly constricted behind ; 

 pronotum level, not distinctly impressed ; abdomen not acuminate, with 

 the tifth segment equal in breadth to the second." The genus, when 

 described by Dr. Sharp, included one species from Chili, two from New 

 Zealand, and one from Plymouth, the latter being closely allied to one of 

 the jSTew Zealand species, and perhaps having been originally imported, 

 although it seems to have at any rate established itself as British. 



T. (Trogophloeus) anglicanus, Sharp (Ent. Mo. Mag., I.e. 232). 

 Black, with the Mutennje and legs fuscous-red, depressed, very finely and 

 thickly punctured, dull ; elytra much longer and broader than the 

 thorax. L. 3 mm. 



Plymouth (J. H. Keys and Cameron). First discovered by Mr. 

 Keys. 



"This insect," according to Dr. Sharp, "is about the size of 

 T, arcuatus, but in nearly all other respects differs greatly from that 

 species; the form is depi-essed, the surface densely and very finely 

 punctate, and dull on account of this sculpture and the minute pubes- 

 cence ; in these respects 7'. fm(/Zica.?ms reminds one of Caji2is ser iceus and 

 other mai'itime species. The antennae are not much thicker towards 

 the apex and the angles of the joints are more rounded than they 

 are in the other species of TrogojyJihKUS ; they are dark in colour, but 

 not black, the basal joint being rather darker than those following it. 

 The head is narrower than the thorax, very finely punctured, a little 

 depressed near the antennal tubercle, but the surface between the two 

 tubercles is but little convex; the eyes are rather small, and do not 

 extend to the back of the head, from which indeed they are separated 

 by a considerable interval. The thorax is much narrower than the 

 elytra, a good deal nairowed behind ; the front angles are remarkably 

 rounded and broad, in fact, quite indistinct ; there is no transverse 

 impression on the surface, but there is a distinct, though very slight, 

 longitudinal elevation at the base in the middle. The elytra are one 

 and a half times the length of the thorax, very flat, completely dull. 

 The abdomen is remarkable for the extremely dense and fine punctua- 

 tion and pubescence." 



Mr. Keys and Dr. Cameron took a fair series of the insect in k 

 tidal creek near Plymouth at a locality more inland than Plymouth 

 Sound ; there is no foreign shipping in it, and no ballast is allowed to 

 be put out in the neighbourhood. Xo foreign vessel, as far as can be 

 ascertained, has been in the creek for forty or fifty years. It is.
