Addenda. — I have in vain searched on the juniper and flax 

 for Thrips juniperina and Thr. variegata. Thr. fusca 

 (Muller), on account of the insinuated resemblance to Thr. 

 fasciata, may perhaps be the same with Melanthrips obesa, 

 but the description is too slight to afford any assistance in 

 identifying the species intended.
