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 E. 

 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. 



Tychotyeus, gen. nov. 



Body moderately convex, subovate, rather elongate, pilose. 

 Ilead^ 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 in- 

 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. 



]\Ietasternum of moderate length. Front coxce contiguous, 

 elongate, exserted. Middle coocce with large circular cavities, 

 separated by the well-developed mesosternal process, their 

 trochanters elongate. Bind coxce moderately widely separated, 

 prominent, their trochanters rather long and thick. Legs 

 long and slender. Tarsi with subequal terminal joints, the 

 first very short, with two equal claws. Antennce 11 -articulate, 

 moderately approximate at the base. Antennal tubercles 

 variable, usually large and prominent, with a well-marked 

 intervening channel. Ahdomen composed of six nearly equal 

 segments. 



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 Tyrus 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 sternalisj sp. n. 



Convex, subovate, rather elongate ; shining, red, head, 

 thorax, and hind body sanguineous, tarsi and palpi yellowish ; 

 pubescence flavescent. 



Bead almost as broad as the middle of tlie thorax, rounded 

 behind ; vertex convex, near each eye there is a distinct fovea
