This paper gives a systematic description of 34 species of Orthoptera 

 collected in the summer of 1915 in Northern Mongolia. Of these, 13 

 species are new to Mongolia, while one, Platijdeis homini, is new to 

 science. A key for the identification of the males of the genus 

 Chrysockraon is included.

The Longicorn, Parandra caspia, Men., is very common on the 

 southern coast of the Caspian Sea, where it breeds in practically all 

 the local trees except figs {Ficus), though the larvae and pupae are 

 chiefly found in willow {Salix), poplars (Popidus), alders {Alnus 

 ghdinosa), and honey locust {Gleditschia triacanthos). 



A description of the larva and pupa is given, with some observations 

 on the life-history. The larval stage extends over three years, while 

 the pupal one lasts two or three weeks ; the beetles remain inactive 

 till the fat-bodies are exhausted, when they are able to fly ; they bore 

 mines which usually end in the first cavity they meet on their way, 

 frequently those caused by larvae of Cossus or Zeuzera ; in rare 

 instances the mines lead outside the tree.

This is a list of Scolytids observed by the author during 1915-1916 

 in the environs of Petrograd. 



Scolytus {Eccoptogaster) ratzeburgi, Jan., has of late years seriously 

 infested birch trees, large numbers having perished. S. {E.) rugidosus, 

 Ratz,, though nearly absent in the locahty ten years ago, is now present 

 in large numbers on sorb, bird-cherry and medlar trees. PhloeophtJiorus 

 (Phthorophloeus) spinulosus, Rey, is very common in the lower, dying 

 branches of old spruce trees ; adult beetles were frequently found in 

 winter in pairs in the brood-galleries, the larval mines from the latter 

 containing larvae of various ages, pupae and also young beetles. The 

 adults were frequently observed to oviposit after hibernation in the 

 brood-galleries. Hylesinus crenatus, F., has been present for some 

 years in old ash trees. H. fraxini, Panz., was very rare a few years 

 ago, but now is common in ash trees. Myelophilus pinip)erda, L., and 

 M. minor, Hart., infest pines, and very rarely spruces, and are regarded 

 as the most dangerous enemies of pines.
