578 Mr. D. Sharp and Mr. F. Muir on the Comparative 
and the ends of them coiled up into balls as in the Cara- 
bidae ; situate near their extremity are six small, simple, 
globular glands attached to the vasa deferentia by slender, 
short ducts. These globular glands are simple and have 
none of the complex structures of such forms as Jelolontha 
vulgaris, 
Trox penicillatus (Pl. XLII figs, 4 and 47). 
This is similar to 7. scaber, but more complex, especially the 
median lobe. There is no differentiated sac, 
Trox sp, 21, N, Australia (Pl. XLII fig. 1). 
Median lobe broad, flattened, curved and pointed at tip, with a 
little ridge running down the middle of the dorsal side; median 
orifice across tip on ventral side. Lateral lobes well developed, 
embracing the lateral edges of median lobe nearly to the tip, not 
meeting together at base either on dorsal or ventral side. Internal 
sac small but distinct, without armature. 
Tro« sp, ? 2, N. Queensland. 
This is of the same type as 7. sp. ?1; the median lobe is broad, 
flattened and pointed at the tip; the median orifice situated across 
the tip, the lower pointed lip of which turns down when the 
sac is evaginated. Lateral lobes only embracing the sides of the 
median lobe and not meeting on either side at their bases. Basal- 
piece small, membranous on dorsal side, large at the sides where 
the lateral lobes are articulated and a narrow chitinous strip on the 
ventral side. Internal sac short, with curved chitin plate as 
armature. 
Trox suberosus. 
Similar type to Tvox sp. ? 2, but the basal-piece is longer. 
Internal sac short, covered with fine soft hair, and on the ventral side 
with a curved chitinous plate which projects beyond the sac when 
evaginated. 
Glaresis becker. 
Median lobe large, well developed, with pointed tip turning up 
dorsally ; membranous on ventral side; median orifice on ventral 
side near tip; point of articulation on dorsal side. Lateral lobes 
shghtly longer than median, nearly meeting at their base on 
dorsal face ; concave on the inner side and embracing the dorso- 
lateral part of the median lobe; tips bluntly pointed. Basal-
