XIII. — New Genera and Species o/'Corylophid^ in the Collec- 

 tion of the British Museum. By the Rev. A. Matthews. 



TiiKOUGH the kindness of Dr. Gunther and Mr. Waterhouse 

 1 have been enabled to examine the collection of unnamed 

 Corylophidaj contained in the British Museum, an accumula- 

 tion from various parts of the world, but chiefly the results of 

 the explorations of Messrs. Bowring and Thwaites in the 

 tract extending from the north of China to Borneo and the 

 other islands of the Malayan archipelago. As might have 

 been expected, I have found these insects of the most novel 

 and interesting description, exhibiting strange forms of un- 

 known genera, and some yet stranger and more abnormal 

 species of genera already discovered. The following list 

 will prove both the richness and the novelty of this collec- 

 tion : — 



New Species. 



Sacium imperiale. Peltinus orieiitalis. 



alutaceum. Coiylophodes glabratus. 



Arthrolips rotundatus. unicolor. 



suffasus. iusignis. 



bimaculatus. Oligartlirum Waterhousii. 



senegalensis. Catoptyx Bowriiigii. 



croceus. Lepadodes chilensis. 



semipunctatus. Aphanocephalus impunctatus. 



flavicollis. quadrimaculatiis. 



elegans. vitreiis. 



Sericoderiis crassus. dissiiuilis. 



aiistralis. 



There are also examples of other rare species, such as Rhypo- 

 hius velox, Anisomeristes castaneuSj and Aphanocephalus Wol- 

 lastoni. 



In the present descriptions I shall mention such characters 

 only as will suffice for the recognition of the new genera and 

 species. 



Sacium imperiale, sp. nov. 



Long. 2-30, lat. 1-50 mm. Ovatum, latissimum, modice coavexum, 

 nitidulum, modice et sat confertim punctatum, piJis brevibus aureis 

 vestitum, castaneum; prouoto antice circulariter rotuudato, modice 

 refiexo, et rufescente ; elytris castaneis, macula humerali, macula 

 magna aquiliformi dorsali atque marginibus la^te rufis ; pedibus 

 longis, gracilibus, Isete fla\'is ; anteunis longis, gracilibus, artieulis 

 duobus apicalibus Isete flavis, cieieris obscurioribus. 



This fine species is remarkable for its great size and breadth^ 

 and for the variegation of its colour. At first sight it would 

 appear to belong to a distinct genus, but since the organs 

 of its mouth and the arrangement of the skeleton of the
