MESSRS. R. E. TURXER AND J. WATERSTON ON THE 



coxisque troclianteribusque anticis flavis ; antennis ferrugineis, 

 scapo pedicelloque supra leniter infuscatis ; alis hyalinis, venis 

 fuscis. 



Long. 9 mm. ; antennarum long. 7 mm. 



c^* . Very near L. multiarticulatum, but differs in the colour of 

 the antennjB, in the absence of a yellow apical band on the median 

 segment, in the distinctly shorter third antennal joint (in multi- 

 articulatum this joint is twice as long as broad, in the present 

 species rather less than half as long again as broad), and in the 

 smooth external area of the median segment. The antennae 

 are 49- jointed.

This species, the type of the genus, is unknown to us.

Cameron's description of this genus is good, and he is probably 

 correct in connecting the genus with the Phygadeuonini, though, 

 as he remarks, it has no near relationship with any other genus. 

 Cameron only gives Australia as the locality for his species, 

 which, however, we can now record from Tasmania, together 

 with a new species described below. 



PCECILOCRYPTUS NIGRIPECTUS, Sp. n. 



$ . Flava ; mandibulis apice extremo, antennis, articulis sex 

 basalibus subtus flavis, fronte sapra antennas, area circa ocellos,

 medium attingente, lateribus et margine postico late, mesosterno, 

 scutello basi, segmento mediano basi, lateribus late, supra augus- 

 tissime, tergito tertio, apice extremo excepto, tergito sexto,

Long. 5'5 mm. ; terebrse long. 2*5 mm. 



5 . Antennae 22-jointed, the basal joints very slender, the 

 apical joints strongly thickened, the last seven broader than 

 long, the five basal joints of the flagellum long and slender, joints 

 6 to 9 slightly thickened, from the tenth more abruptly 

 thickened, attaining the greatest breadth at the fifteenth. Face
