COLHOPTERA 407 



(2) Lahroccrns gravidns, sp. nov. 



Niger, antennis sordide fulvis ; elytris pube grisescente plus minus variegatis. 

 Long. 3^- — 4 mm. 



Closely allied to L. luocrcns but readily distinguished by the colour and form of 

 the antennae, which are much paler, and in the male more largely developed than they 

 are in L. niocrcns. The basal joint is piceous-yellow, the others yellow, more or 

 less dusk)'. In the male the third joint is very small, the fourth is more than twice 

 as large, si.xth — tenth transverse, eleventh very long, about as long as the five 

 preceding it. In the female the antennae are very much like those of L. inocrciis, 

 except for the pallid colour. The characters of the elytra and thorax are very much 

 those ot L. luociriis. The legs are usually paler in colour. Eleven specimens.

 (Perkins). 



(3) LLxhroccriis simplex, sp. nov. 



Niger, antennis flavescentibus, elytris pube fusco-nigra fere aequaliter vestitis. 

 Long. 3-4- mm. 



This is smaller than L. gravidus, and the pubescence is darker and shows very 

 little trace of any pattern, and the male antennae are smaller with considerably shorter 

 terminal joint. Seven specimens.

(4) Labroccnis concolor Sharp. 



Labroccrus coiico/or Sharp, Tr. Dublin Soc. iii. 1885, p. 149. 



Mr Perkins has lound only one specimen of this species ; it is a female and agrees 

 well with the unique male on which I based the species. It is robust with a very 

 shining thora.x ; the elytra have much granular punctuation at the base, the pubescence 

 is darker than in most of the other forms, and there are no fasciae on the elytra.

(5) Labroccrus curticoruis, sp. nov. 



Niger, robustus, conve.xus, late ovalis, sat nitidus, elytris fascia maculisque pubes- 

 centiae grisescentis, maris antennis articulis 2° — 7"" testaceis. Long. 3-^ mm. 



Nearest to L. concolor, but with a well-marked development of the pale setosity, 

 and with the antennae of the male shorter than in the allied forms. We have only one 

 specimen. The apical joint of the antenna is shorter than in the other species of this
