Pezomachus brevis, n. s. 

 Niger, pedibus piceis. 



This species comes in Foerster's division A. II. a. yy., 

 next to P. pumilus, but is much larger, and the 7th joint 

 of the antennae is only a little longer than broad. 

 Foerster says the thorax is of ordinary length, with the 

 metathorax short ; in this the meso- and metathorax 

 are of the same length, and very short ; 2nd joint of 

 flagellum a little longer than the 1st, this about two and 

 a half times as long as broad ; 5th rather longer than 

 wide ; head transverse, much wider than the thorax ; 

 meso- and metathorax of about equal length, very short ; 

 metathorax with no trace of the transverse line. Thorax 

 much higher than long ; back part of metathorax flat 

 and slanting. Abdomen ovate ; spiracles scarcely pro- 

 truding ; post-petiole broad ; abdomen covered with 

 scattered hairs ; aculeus not quite so long as the 1st 

 segment. 



Black ; scape and 1st joint of flagellum reddish brown; 

 mouth and legs brownish red, four anterior femora 

 towards the base rather darker ; hind femora reddish 

 brown, as is the extreme apex of hind tibiae below ; in- 

 cisions of anterior segments of the abdomen slightly 

 pale ; 6th segment entirely pale. Length about 4 mm. 



Taken by Mr. F. P. Pascoe at Dover. 



Pezomachus hieracii, n. s. 

 Niger, pedibus piceis. 



This Pezomachus belongs to Foerster's division A. I. h., 

 and comes next to P. tener. 



Head transverse, rather slanting behind the eyes. 

 Antennae moderate ; 1st and 2nd joints of flagellum sub- 

 equal in length, about three times as long as wide, the 

 5th rather longer than wide ; mesothorax short ; meso- 

 and metathorax of equal length, the back part of the 

 latter slanting and flat, without the transverse ridge ; 

 1st segment of abdomen broad at the apex; spiracles 

 not projecting ; the remaining segments transverse ; the 

 2nd and 3rd much shorter than usual, scarcely so deep 

 as the width of the apex of the 1st segment, densely and 

 uniformly covered with pubescence ; aculeus a little 

 longer than the 1st segment.
