33G ADDENDA 



First taken by Mr. Muir, and afterwards by Dr. Sharp, in shingle 

 on the banks of one of the small rivers in the New Forest, in August 

 1911 (v. Ent. Mo. Mag. xlvii. (2 Series xxii.) 1911, 227). 



It must be admitted that this species comes extremely close to 

 II. longida and one or two other closely allied species, and its specific 

 value may be regarded as to some degree doubtful. The external sexual 

 differences are very slight. 



H. (Atheta) liliputana, Bris. Very similar to II. amicula, Steph., 

 from which it is distinguished by its smaller size, more shining thorax 

 and elytra, and much more scattered punctuation. Black, rather shin- 

 ing, elytra brown, legs brownish-yellow. Head broad, antennae rather 

 short, the last joint nearly double as broad as long. Thorax narrower 

 than elytra, rather strongly transverse, with the sides only slightly 

 rounded, very finely and not thickly punctured, and veiy finely pubes- 

 cent with fine cilia at the sides. Elytra about one-third longer than 

 thorax, very finely and somewhat spainngly punctured, finely pubescent. 

 Hind body shining, the first three visible segments very finely and 

 rather sparingly punctured, the others very sparsely punctured. L. 

 Ij mm. 



Taken by Dr. Malcolm Cameron near Brockenhurst in small car- 

 cases, and introduced by him as British (Ent. Mo. Mag. xlvii. (2 Ser. 

 xxii.) October 1911, p. 223). 



This is a very small and obscure species ; in point of size it is 

 intermediate betAveen H. inquinula and H. mortzcoruon ; from the 

 former of these it may be known by its broader and more robust build, 

 broader and flatter head, and different sculpture, while the smaller size, 

 much more shining head and thorax, and more finely punctured hind 

 body will distinguish it from H. inortuorum. 



Oligota ytenensis, Sharp (Ent. Mo.Mag.xlviii. (2 Ser. xxiii.) 1912, 

 p. 121:). Very small, narrow, and sub-linear; black, with the antennae 

 and legs red, the club of the former fuscous ; head and thorax very 

 shining, antennte rather short, the club abrupt, the eighth joint con- 

 siderably longer than the very short seventh joint ; elytra intensely 

 black, rather strongly punctured, wings aborted ; last segments of the 

 hind body only slightly paler than the preceding. L. IJ mm. (in quite 

 fresh specimens). 



In decaying sea-weed, Lymington, very rare ; Dr. Sharp also has a 

 specimen from Edinbvirgh, which he believes was not found in sea-weed. 



Dr. Sharp says that this very distinct little species may be placed 

 between 0. atomaria and 0. pitsilUma. It has much the appearance 

 of 0. atoina7'ia, but may at once be distinguished by the small elytra, 

 which are scarcely longer, and almost narrower, than the thorax. It 

 is narrower and darker than 0. pusillima, and both of these species 

 have elongate wings, whereas in 0. ytene^isis the wing is only about the 

 length of the elytra.

 Skand. Col. ix. 230). Keddish-yellow, with the head greyish-black, the
