Clypeaster discedens, -J. Duv. — " This seems to me to be distinct from C. obscums. 

 Sahib. It is rather more compact {ramassei, the elytra are more faintly punctured, and 

 their suture more finely, or scarcely at all, elevated behind," 



Clypeaster nitens, Rey. — " Closely allied to S. densatum, Eeitter. It is nevertheless 

 distinguished by its rather more parallel shape, more shining surface, and especially by its 

 more rounded sutural angle of the elytra. — Spain." 



Arthrolips regularis, Reitt. — "This species is found in Provence. The variety 

 A. hci-iculUs, Rey, is possibly a distinct species. It is perceptibly smaller, the prothorax is 

 almost smooth on the disc, the elytra are ver.y obsoletely punctured, and more contracted 

 behind. — Hyeres." 



Corylophus nigripennis. — "I have separated from ('. xnbltivipmnis a Conjlophus of 

 a slightly smaller size, with almost entirely black elytra, equally finely punctured, but with 

 the interstices smoother and more shining. It may be merely a variety." 



Orthoperus peregrinus "is perhaps O. an.vius. It is smaller, rather smoother 

 and more shining than O. an.rius : less shining and less distinctly punctured than 0. 

 pilosiusculus." 



Of the species thus noticed by M. Rey, I have not seen types of Clijpeiister nitem, 

 Arthrolips Itcvicollis, (\iri/loj>hns iii//njieiiHis, or Arthrolips perccirinus, and therefore cannot 

 express any opinion of their merits ; but I have received from various sources specimens 

 labelled " .5. nanum." Of these some were identical with S. densatum, others with S. pusil- 

 lum, and one with Arthrolips rufithorax; but none resembled Sacium Rhenannm. 



The only type of Clypeaster lividus which I have seen was identical with Sericoderiis 

 lateralis. 



I have examined many examples of C. discedens, and all have proved identical with 

 Arthrolips obscurus. 



In the foregoing observations I have merely recorded my own experience, but in the 

 confused state of nomenclature prevailing in this family it would be rash to assert any 

 claim to infallibility. Specimens often seem to have been labelled promiscuously or by 

 conjecture ; in one collection I met with Sacium pusillum represented by a miscellaneous 

 series comprising S. Damryi, densatum, and latum, Arthrolips humilis, Sericoderus lateralis, 

 and Anis. nerelierii. 



RYE (E. C.) 

 Entomologists' Monthly Magazine, vol. x. p. 167 (1873). 

 A new species of Aphanocephalus is here described by Mr. Rye under the name of 

 A. Wollastoni. The description is short, and does not enter into details. 



REITTER (E.) 

 Herr Eeitter has done much good work among the ' 'un/lophidtr, and increased the list 

 by the addition of twenty new species, separated with correct discrimination, and described 

 with his wonted accuracy. 



In ' L'Abeille,' vol. xvi. pp. 1-12 (1877), he has given a revision of the species 

 Sacium and Arthrolips, and to those previously described added the following new 

 species, viz. : — 



Sacium Rhenanum. 

 latum, 

 orientale. 

 densatum. 

 Arthrolips regularis. 

 ,, ferrugatus. 



To these he subsequently added many other species at different times, and in various 

 publications.
