236 SUMATRAN LUCANIDAE. 



specimens were inexactly labelled » Ludeking, Sumatra" 

 in stead of »Ludeking, Ternate." 

 Odontolabis Cuvera Hope. — Two males and a female of 

 this species in the Leyden Museum are (doubtless in- 

 exactly) labelled » Muller, Sumatra." 

 Eurytrachelus bucephalusFertj. — The <ƒ specimen from Sumatra 

 (Ludeking) recorded by Snellen van Vollenhoven under 

 the above name belongs to Eurytrachelus Titan Boisd. 

 Eurytrachelus saiga Auct. (= Gypaëtus Casteln.) is recorded 

 by Parry (and after him by the Authors of the Mu- 

 nich Catalogue and Dr. Gestro) as inhabiting Sumatra. 

 I believe, however, this statement to be based upon 

 incorrect identification of specimens of the Sumatran 

 Eurytrachelus purpurascens Voll. (? = elaphus Herbst). 

 Aegus acuminatus Fabr. is likewise recorded by Parry as a 

 Sumatran species. Most probably, however, these speci- 

 mens belonged to the Sumatran Aegus ogivus H. Deyr. 

 Aegus impressicollis Parry. — Four specimens (three males of 

 the varietas minor and a female) brought home from 

 Sumatra by the Dutch Scientific Sumatra-Expedition 

 were sent back by Parry under the above name. A 

 careful examination , however , convinced me that these 

 specimens belong to Aegus ogivus H. Deyr. 

 Three other species, recorded by the authors as coming 

 from Sumatra , are unknown to me , viz. Lucanus (Aegus) 

 lunatus Weber, Lucanus (Aegus) inermis Fabr. and Luca- 

 nus (Figulus?) punctatus Fabr. 



On the other hand I am acquainted with an unnamed 

 Sumatran species of Prosopocoelus (a Q from Deli in the 

 Leyd. Mus.), Cyclommatus (a Q from Deli in the Leyd. 

 Mus.) and Aegus (a <ƒ from Mt. Singalan in the Genoa Museum. 

 Finally three species of Lucanidae are described from Nias, 

 an island west of Sumatra , which species perhaps may also 

 belong to the Sumatran fauna, viz. Cyclommatus Maitlandi 

 Parry (not identical with C. faunicolor Westw.) , Odonto- 

 labis gracilis Kaup and Odontolabis inaequalis Kaup.
