Hill (G. F.)- A new Species of MordeUistena (Coleoptera, Fam. 

 Mordellidae) Parasitic on Termites.— Proc. Linn. Soc. N.S.W., 

 Sydney, xlvii, pt. 3, 15th September 1922, pp. 346-347, 2 figs. 



MordeUistena erythroderes, sp. n., is described from North Queens- 

 land, where it was found in rotten logs infested with Calotermes 

 {Glyptotermes) nigrolabrum, Hill. This species would be hardly likely 

 to prove of any practical value unless it could be established in the 

 colonies of some of the more destructive species of termites, and 

 this seems improbable.

The rearing of parasites of Xylotrechns quadripes, Chev. (coffee 

 borer) has continued on the same lines as before [R.A.E., A, x, 519] 

 in spite of adverse weather conditions. The multiphcation of the 

 Braconid, Doryctes strioliger, Kieff., has been rather retarded by 

 storms. The Bethyhd, Sclerodermus domesticus, Kieff., is increasing 

 much more regularly than last year, although the insects only appear 

 in fine, warm weather. The rearing of this species is somewhat 

 hampered by the activities of a small parasite that attacks both the 

 larvae of the borer and those of the Bethylid. S. domesticus seems to 

 be the most promising of all the parasites, as it is the hardiest species, 

 is very active in reaching its host, and has a longer adult hfe than 

 the others. 



The Agricultural Appropriation Act, 1922-23.— £#/. Sta. Record, 

 Washington, D.C., xlvii, no. 1, July 1922, pp. 1-8. 



The total allotment for entomological work under the annual acts 

 making appropriations for the support of the U.S. Department of 

 Agriculture has been increased from about £334,000 (at par) to about 

 £356,000. In addition, £110,000 has been allotted for the campaign 

 against the pink bollworm [Platyedra gossypiella, Saund.] and £5,000 

 for the control of the Mexican bean beetle [Epilachna corrupta, Muls.]. 

 The chief increase is the £120,000 allowed' for the prevention of the 

 spread of the gipsy moth [Porthetria dispar, L.] and of the brown-tail 

 moth [Nygmia phaeorrhoea, Don.] (an increase of £40,000), and that of 

 £3,000 to be used against the camphor scale [Pseudaonidia duplex, 

 Ckll.l. Other pests against which special allotments have been made 

 include the date scale [Parlatoria blanchardi, Targ.], European corn 

 borer [Pyrausta nubilalis, Hb.], grasshoppers and various pests of 

 vegetable crops and stored products.

 Control.— ///mo /s Agric. Expt. Sta., Urbana, Circ. 252, March 

 1922, 4 pp. [Received 3rd October 1922.] 



The control of the San Jose scale [Aspidiotus perniciosus, Comst.] 

 by spraying in southern IlUnois has proved unsatisfactory on a number 

 of occasions. From observations it would seem that the great deviation 

 in the amount of spray applied under commercial conditions from that 

 used experimentally may account for this. To obtain successful 

 results it is essential that the diluted spray should contain 151b. 

 sulphur in 50 U.S. gals., with which the entire surface of the trees-
