Various Tipulids of the genera Tipula and Pachyrhina are found in 

 abundance in the governments of Volhynia, Minsk and Mohilev. The 

 larvae were found experimentally to prefer salad and cabbage to the 

 roots of grasses. Some of them proved to be infested with Tachinid 

 parasites, and they are also destroyed by birds and some predaceous 

 beetles. They can be collected early in the morning, when they 

 emerge on the surface of the soil, and their destruction may be assisted 

 by utilising poultry. These larvae are not considered to be so seriously 

 injurious to grain crops as in market-gardens. Boiling the soil is not 

 regarded as an effective method of control.

A collection of species of Haplothrips from the Poltava Station, 

 having been sent to the author at Vienna by N. V. Kurdjumov, a 

 description is here given of the morphology of the species of this very 

 variable genus. The genus Haplothrips, Serv. {Anthothrips, Uzel) is 

 undoubtedly the most compUcated of the Thysanoptera and a critical 

 comparison of the Russian species is destined to serve as a basis for 

 the pending revision of the whole genus. The species dealt with 

 include : Haplothrips statices, Hal. ; H. tritici, Kurdj. ; H. acuhatus, F. ; 

 H. kurdjumovi, which is regarded as a variety of the previous one, 

 having been found by Kurdjumov inside galls of Aphis crataegi and 

 breeding also on eggs of Sciaphobus squalidus ; this species 

 also resembles in some respects H. japonicus and H. oryzae, and 

 H. cahirensis ; H. heymonsi, sp. nov., obtained from Turkestan, 

 Syr-Daria, Transcaucasia and Tiflis, and allied to H. kihnandjaHcus 

 and H. usitatus on one side, and H. oryzae and H. japonicus on the 

 other.

Two generations of Haplothrips aculeatus were observed in 1912, 

 the food-plants being rye, maize, Italian millet and oats. Cases of 

 cannibalism amongst the larvae were observed, as well as a case in
