48 LUCANID.^. 



the prothorax. A feature particularly noted as distinctive of 

 the true L. singularis is the comparative smoothness of the 

 legs. Those of L. furcifer, on the contrary, are very strongly 

 and closely sculptured. 



At the end of this genus will be found a translation of the 

 very imj^erfect description by Planet of the unique female type 

 of L. singularis, which I have not been able to examine. 



4. Lucanus fryi. (Plate IV, fig. 3 ; Plate V, fig. 3.) 



Lucanusjryi Boil.,* Trans. Ent. Soc. Lond. 1911, p. 434, pi. 34, fig. 3. 



Dark chocolate-brown, the legs entirely dark, the lower 

 surface rather closely clothed with short pale yellow hair, the 

 upper surface entirely bare, with the exception of the head, 

 the scutellum and the base of the mandibles, as well as the 

 sides of the pronotum in the male. It is a large stout-bodied 

 species. The club of the antenna composed of four long, nearly 

 equal lamellae. The jarosternum prominent, rounded and 

 strongly compressed behind. 



$. Very dark, with the head and legs generall}- black, the 

 upper surface not shining. The head is densely rugose, with 

 the front angles acute and the eye-ridges rather j^rominent 

 behind. There is a strong curved ridge on each side of the 

 posterior part of the head. The jironotum is closelj^ punctured, 

 the punctures upon the anterior half larger and denser than 

 those upon the posterior half. The lateral margin is gently 

 rounded to beyond the middle, where there is a sharply defined 

 angle, and gently concave to the hind angle, which is also 

 sharply defined. The elytra are very finely punctured and 

 rather closely so, except in the anterior dorsal part, where the 

 jDunctures are few and very minute. The legs are stout ; the 

 front tibia ends in a long, very bluntly bilobed process, the 

 lateral spines of the middle and hind tibiae are strong and the 

 hind tibia has three sharp terminal processes. 



(^. The body is moderately elongate. The head is flat and 

 surrounded by an elevated ridge rather broadly interrupted in 

 the middle behind, the front angles sharp and double and the 

 lateral lobes broadly rounded. There is a long clypeal process, 

 not very broadly forked at the end. The pronotum is short 

 and broad, finely rugose at the sides, where there is a thin 

 clothing of short yellow hairs, and finely punctured elsewhere. 

 The front angles are bluntly produced, the lateral margins very 

 strongly but bluntly angulate in the middle and the hind 

 angles sharply defined. The elytra are very finely punctured, 

 closely, except in the anterior dorsal jmrt, and densely at the 

 apices. The front tibia is sharply toothed externally and the 

 terminal fork is long. The terminal ]irocesses of the hind 

 tibia are not long or sharp.
