Hab. — Afric. occ. Coll. Parry. 



This elegant little species lias on a cursory inspection 

 a very strong resemblance to Metopodontus Savagii (var. 

 minor, PL II. fig. 4); its armed mandibles, the form of its 

 head and clypeus, and the colour of its legs, afford, however, 

 ample distinguishing characters. Acquainted with the c? 

 var. minor only, I refer it provisionally to the genus Meto- 

 jwdontus, the minor development in several of the species 

 of this genus being destitute of the tubercles in front of 

 the head so conspicuous in the var. max. as already 

 stated. I have great pleasure in naming this insect after 

 my friend Mr. Swanzy, from whose interesting collection 

 of West African Lucanoidca I have obtained much valu- 

 able information, and to whom I am indebted for the 

 addition of this unique insect to my collection. 



Prosopocoilus Wallacii, Parry. 



I am indebted to M. Van Vollenhoven for the addition 

 of this rare species to my collection. An unique speci- 

 men of the $ captured by Mr. Wallace, was described 

 in my former publication. The following brief diagnosis 

 may be sufficient to characterize the female. 



$ . Niger, supra nitidissimus, subparallelus ; elytris 

 dorso fusco-castaneis, linea angusta fulva ab humero fere 

 ad apicem ducta notatis, marginibus nigris. 



Long. Corp. unc. 1, lin. 2. 



Hah. — Halmaheira (Gilolo) . 



Slightly convex, above very shining. Head subquad- 

 rate, in front and at the sides with large shallow and often 

 confluent punctures, behind smooth, rounded in front of 

 the eyes; mandibles short, strongly punctate, slightly 

 grooved on the upper surface, and armed with a short
