1096 COLEOPTERA 



easily detected. The eleventh joint of the antenna appears merely 

 as a pubescent apex to the tenth. The thorax has the anterior part 

 of the sides slightly narrowed, the front angles slightly prominent, 

 and the hind angles also distinct. The striation of the elytra is very 

 strong, even the sutural stria being broad and deep, and the striae 

 not irregular. The metasternum is very short. 



I am not sure but that there may still be two species mixed 

 under this name ; some of the individuals are only 2mm. long, and 

 are piceous in colour, the thoracic depression less, and more dis- 

 tinctly separated into two by a broader space ; I have not, however, 

 seen enough examples of the two forms to enable me to come to a 

 decision, and prefer treating these smaller specimens merely as a 

 variety. 



Greymouth. I have retained for this species the trivial name 

 under which it has been distributed by Herr Eeitter. 



1950. P. latitans, n.s. (Sharp ; Trans. Boy. Dub. Soc., 1886, 

 p. 390.) Nigerrimus, nitidus, oculis rninutissimis, antennis pedi- 

 busque runs ; prothorace oblongo, fortius punctato, disco leviter 

 bi-impresso ; elytris profunde sulcatis, sulcis flexuosis. 



Long., 3Jmm. 



This is very similar to P. sulcatissimus, but is distinguished by 

 some good characters ; the lateral margin of the thorax just ^before 

 the front border becomes thinner, and thus the thorax has an ap- 

 pearance of being suddenly though slightly narrowed in front, and 

 there is no prominence of the front angle ; the disc has only two 

 slight impressions, separated by a rather broad space ; there is no 

 transverse depression on the wing-cases behind the scutellum, 

 whereas in P. sulcatissimus the second stria on each elytron is con- 

 nected by a transverse depression extending behind the scutellum, 

 so that its hind margin is raised ; and in P. latitans the sculpture of 

 the grooves or striae is not so effaced as it is in P. sulcatissimus, and 

 the eyes are even more minute.

1951. B. COgnatllS, n.s. (Sharp; Trans. Boy. Dub. Soc., 

 1886, p. 390.) Niger, antennis elytris pedibusque ferrugineis ; pro- 

 thorace subquadrato, fortiter punctato, dorso foveolato, angulis 

 posterioribus argute rectis ; elytris apicem versus subcostatis. 



Long., 4Jmm. 



Very closely allied to B. mc&stm, though readily distinguished by 

 the colour of the legs and elytra; the sculpture is almost identical 

 in the two species, except that it is a little more obsolete on the 

 elytra in B. cognatus ; the latter is, however, of rather less elongate 

 form, and the thorax is a little shorter, with the hind angles more 

 prominent, and there is no trace of any tubercle on the middle of 

 the prosternum behind. 



Bealey. Helms ; one example.
