ySi^ulothrips hrevicortiis, sp. n. 



? . — Length 1*25 mm. 



Reddish- to chestnut-brown ; fore-legs and third antenna 1 

 joint yellowish-brown. 



This species comes in the " fasciatus " group with banded 

 wings, and differs from all the species excepting fasciatus in 

 having the abdomen unicolorous. Apart from its small size, 

 hrevicornis may be separated from fasciatus by its shorter 

 antennae, which are approximately 2'2 times (instead of about 

 3 times, in fasciatus) the length of the head. The inter- 

 mediate antennal joints are relatively shorter compared with 

 their breadth ; joints 3 and 4 are practically subequal, 

 whereas in /a*c/a^w6- joint 3 is 1"2 times the length of 4. In 

 the species of the "fasciatus" gioup in which the base of 

 the abdomen is banded with white the last four (6 to 9) 

 antennal joints are together much longer than the fifth ; 

 in fasciatus they are practically equal to the fifth (20 : 19), 

 whilst in brevicornis they are much shorter than the fifth 

 (19 : 14).
