Felt (E. P.). New Asian Gall Midges.— JL New York Entom. Soc, 

 Lancaster, Pa, xxiii, no. 3, September 1915, pp. 173-184. 



The following Asiatic gall nudges are described : — Didactylomyia 

 ceylonica, sp. n., from Pcradeniya, Ceylon ; Microperrisia pulvinariae, 

 sp. n. , reared from Pulvinaria on citrus in Manila ; Dentifibida ceylonica, 

 sp. n., reared from twigs of Cassia alata infested with Hemichionaspis 

 sp. ; D. obtusilobae, sp. n., obtained from Piper nigrum infested with 

 H. aspidistrae and a few specimens of Aspidiotus lataniae ; this midge 

 is probably an enemy of the first-named scale ; Diadiplosis smithi, 

 sp. n., reared from cocoons produced by larvae feeding on Pulvinaria sp. 

 on citrus at Manila ; D. liirticornis, sp. n., bred from mealy bugs from 

 Japan; Xiphodiplosis fulva, gen. et sp. n., from Saisselia nigra on 

 dahlia at Peradenyia ; Arthrocnodax rutherfordi, sp. n., from leaves of 

 Melia azedarach infested with Tetranychus sp. ; A. walkeriana, sp. n., 

 reared from Pseudococcus sp. on coffee ; Androdipilosis coccidivora, 

 gen. et sp. n., from Aspidiotus or Chrysomphalus sp. on Limonia alata ; 

 Dyodiplosis generosi, sp. n., reared from twigs infested with Howardia 

 biclavis and Aulacaspis sp.

Plagiognathus p)olilus passes the winter in the egg-stage in one-year- 

 old apple twigs. The eggs are usually inserted singly either into the 

 tissue of the stem at the base of the leaf-buds or into the bud scales. 

 Campylomma verbasci is found throughout the summer at Rochester 

 Junction, N.Y., breeding abundantly on Verbascum thapsus, L. 

 (mullein), and on apples in nurseries. A description of the various 

 stages is given.

 10 plates, 19 tables. 

 Pinus echinatus, Mill, (shortleaf pine) is attacked by Dendroctonus 

 frontalis, Zimm. (southern pine beetle). The larvae of this insect are 

 active throughout the warmer portions of the year, passing through 

 the bark to the cambium, where long tunnels are formed. The use 

 as fuel of trees which die in autumn and early winter, serves to control 

 this beetle. Rhyacionia {Ketinia)fruslruna, Scud. (Nantucket pine-tip 

 moth) attacks and deforms the growing tips of the branches. The 

 presence of dead tips and pitch exudations are the characteristic 

 external signs of attack. As a rule this insect is not abundant for more 

 than 1 or 2 years at a time. Owing to its quick growth, the pine 

 usually recovers rapidly. Fallen trees become infested during the 

 summer with the larvae of species of Monochamus [Monohammus). 

 The eggs are laid under the bark and the larvae feed on the sapwood ; 

 the heartwood is seldom penetrated. Living trees in the southern 

 States are never attacked. Rapid drying of the logs by exposure 

 to sun and wind, or complete immersion in water, prevents the 

 deposition of eggs.
