and strongly rounded behind; the eyes, though small, are 
more prominent. There are six abdominal segments. ‘This, 
as regards the head and eyes, is intermediate between £. 
costifer and the typical species; but in other respects it more 
nearly resembles the former. I leave it without a name just 
now, as we do not know the sexual characters in this genus. 
TYCHOTYRUS, gen. nov. 
Body moderately convex, subovate, rather elongate, pilose. 
Head, including the eyes, nearly as broad as the widest part 
of the thorax, much narrowed, but parallel-sided, in front. 
Eyes large, convex, with coarse facets, placed near the middle. 
Maxillary palpi quite the length of the head ; first joint not 
extending beyond the side of the mandible ; second elongate, 
its basal half very slender and stalk-like, the other much m- 
crassate and oviform ; third short and thick, almost obconical, 
with a short, slender, basal stem; fourth as long as the second, 
oblong-oval, but with a slender basal stalk, its extremity 
provided with an elongate seta. 
Metasternum of moderate length. ront cove contiguous, 
elongate, exserted. J/iddle cove with large circular cavities, 
separated by the well-developed mesosternal process, their 
trochanters elongate. Hind cove moderately widely separated, 
prominent, their trochanters rather long and thick. Legs 
long and slender. Yarst with subequal terminal joints, the 
first very short, with two equalclaws. Antenne 11-articulate, 
moderately approximate at the base. Antennal tubercles 
variable, usually large and prominent, with a well-marked 
intervening channel. Abdomen composed of six nearly equal 
seoments. 
Dr. Sharp, in his description of Tyrus mutandus (Trans. 
Ent. Soc. 1874, p. 488), remarked that ‘though its cha- 
racters agree in the main with those of Z’yrus mucronatus, in 
its appearance and form it comes much nearer the genus 
Tychus; and though it cannot be associated with that genus 
on account of the double claws, it will probably be ultimately 
referred to a distinct genus.” The position of this genus is 
therefore clearly indicated. 
Tychotyrus sternalis, sp. n. 
Convex, subovate, rather elongate; shining, red, head, 
thorax, and hind body sanguineous, tarsi and palpi yellowish ; 
pubescence flavescent. 
Head almost as broad as the middle of the thorax, rounded 
behind ; vertex convex, near each eye there is a distinct fovea
