GENITAL SYSTEM OF LTCTUS B&UNKEUS. 591 
One point observed was that the tergites of linearis were much more 
strongl}' chitinized than in hrmineus, in which they are very flexible and only 
faintly discernible. 
The male. — The oedeagus was found to agree with the description and 
figures of Sharp and Muir (10), except that the basal margin of the basal 
piece was found to terminate in front of the point of articulation, but not so 
far forward as in brunnnts. Whether the anterior margin of the basal piece 
clipped around the lateral lobes was not observed, as no sections were made. 
In other respects it was similar, and gave the impression of being a more 
robust structure. 
Nothing was found of the testes, but the position and appearance of the 
remains of the vasa deferentia, seminal vesicles, accessory glands, and ejacula- 
tory duct were similar to those of brunnens. 
The two I'ods arising from under the ejaculatory duct as in hrunneus, and 
the " U "-shaped apodeme and apodemal rods were present. 
The female. — The similarity of the extruded " ovipositor " as seen in dead 
females to that of hrunneus has been referred to by others. From the 
preparation made, there were observed the setse-lined valve and what would 
be the spermatheca and common oviduct. Remains of the ovaries were 
present, but the number of ovarian tubes could not be distinguished. The 
ovipositor, in repose, and the apex of the distal portion bore a marked 
similarity to those of hrunneus. Further, the cloacal stalk and short rods, and 
the apodeme and apodemal rods were present. 
From the appearance of the " ovipositor " in repose, it seems that the 
alimentary tract must follow a similar course to that of hrunneus. 
Observations on Stein's ' Female Reproductive Organs in 
coleoptera.' 
Stein (11), in his work on the genital system of Coleopterous females, 
describes and illustrates the organs of several species which in some par- 
ticulars resemble the organs of hrunneus. But this resemblance is so slight 
in most that no comparative deductions can be drawn. There are, however, 
a few points that call for comment. 
The " ovipositor " in each of these cases consists of a tube (" Kloakrohr ■") 
which in repose telescopes approximately one-hall: within the other, but each 
varies in the appearance of the distal portion. In all cases the " ovi- 
positor " is apparently shorter, in comparison to the length of the insect, than 
that of hrunneus and linearis. The rectum, in each of the species referred to, 
enters the inner sheath of the " ovipositor " as in hrunneus. The cloacal 
stalk is found, but it is not clear what distance within the abdomen it 
traverses, and in no case is there any indication of the short rods. 
In the case of those females that are closely related systematically to the 
Lyctids, i. e. Anohium punctatum De Geer {pei'tinax F., domesticum Fourc,
