124 CUCUJID^. 



three finely punctured strife and a raised line near the margins ; legs 

 comparatively short. 



Female : similar to the male, but with the head distinctly narrower 

 than the thorax, the antennfe shorter, with at least the eighth and 

 tenth joints as broad as long, the thorax not nearly so much contracted 

 behind and considerably narrower than the elytra, and the elytral 

 spots mvich larger. L. -|-5 mm. 



Streatle}^, Berks. (Joy and Chitty) : about a dozen specimens 

 found under beech bark in October 11)05, and a few subsequently in 

 the same tree. It occurs in Northern and Central Europe, chiefly 

 under beech bark, but also under bark of plane trees. 



This is one of the most interesting additions to our list that has 

 been made for some years. 



HYPOCOPRUS, Motschulsky. 



H. quadricollis, Reitt. (Verb, zool.-bot. Ges. Wien., 1877, 180). 

 This is the insect standing in our collections as H. lathridioides, Mots., 

 which has not hitherto occurred in Britain. The species are very 

 closely allied, but R. qiuidricoUis is distinguished by having the head 

 plainly narrower than the thorax, the thorax considerably narrower 

 than the elytra, not longer than broad, and the elytra distinctly 

 shorter, being only twice instead of two and a half times as long as 

 together broad. The size is the same in both species, 1-1^ mm. 



In the Ent. Mo. Mag., vol. xxxix. (2 Ser. xiv.) 1903, 301, Mr. 

 E. A. Butlei', in recording several specimens from Camber, near Rye, 

 says that Mr. Newbery has pointed out the necessity of the above 

 alteration to him, and that its correctness has since been confirmed by 

 Mr. Champion. 



SILVANUS, Latreille. 



S. mercator, Fauvel (Rev. d'Entom. Caen. 1889, 132, note); 

 S. frumentarius, Duv. (Gen. Col. d'Eur. ii. pi. 50, f. 248). Very 

 closely allied to ;S'. surinamensis, L., but distinguished by its larger 

 eyes, and as a consequence the small tuberculiform temples, which 

 equal only one-fifth of the diameter of the eyes, and by the male 

 characters ; the antenna? are somewhat shorter and have the two 

 penultimate joints more transverse. In the male the head and pos- 

 terior trochanters are unarmed, and the posterior femora are dentate ; 

 in the female the posterior femoi-a are unarmed and the posterior 

 trochanters are very small and simple. L. 2^—3^ mm. 



King's Lynn, in a bakery (Tomlin) ; Merton, Surrey (Newbery) ; 

 Oxford (Walker). A very useful table of the species of Silvanus is 

 given by Mr. Champion in the Entomologist's Monthly Magazine for 

 1896 (xxxii. (2 8er. vii.), p. 268), and he there predicts thixt S . mercator 

 is certain eventually to be found in Britain. Mr. Tomlin's record 

 appeared in 1905 (Ent. Mo. Mag. xlv. (2 Ser. xvi.) 37). 



This is one of the unsatisfactory introductions that, apparently,
