Mayetiola destructor, according to a number of trustworthy rear- 

 ing records of the Bureau as yet unpublished. In distribution 

 it ranges at least from Maryland to Kansas, as shown by speci- 

 mens at hand, and it will probably eventually be found to occur 

 over the whole of the United States and Canada where wheat is 

 subject to the attacks of the joint w r orms and Hessian fly. 



Aplastomorpha vandinei Tucker. 



Meraporus vandinei Tucker, Can. Ent., vol. 42, 1910, p. 343. 

 Aplastomorpha pra'tti Crawford, Proc. U. S. Nat. Mus., vol. 47, 1913, p. 252. 

 Neocatolaccus australiensis Girault, Mem. Queensl. Mus., vol. 2, 1913, p. 306. 

 A plastomorphaatistraliensis Girault, ~M.em. Queensl. Mus., vol. 3, 1915, p. 313. 



Girault has already stated the above synonymy (Ins. Ins. Mens., 

 5, 1917, p. 1")2) but without indicating definitely to what genus 

 the species should be referred. The writer has compared types of 

 vandinei and pratti. The synonymy of australiensis is accepted 

 on authority of Girault. 



The genera Aplastomorpha Crawford, Neocatolaccus Ashmead, 

 and Zatropis Crawford are much alike and may eventually have 

 to be synonymized. Aplastomorpha may be separated from both 

 the others, however, by the almost total absence of appressed 

 hairs on the thorax and by the fact that the antennae are inserted 

 lower down being distinctly below the middle of face.

p. 402. 



The above cited publication by Hase gives a very exhaustive 

 account of this cosmopolitan parasite of Calandra oryzae and other 

 stored grain pests. Meraporus utibilis Tucker is listed as a, 

 synonym by Hase. 



Previous to receipt of Hase's paper the writer had compared the 

 types of utibilis and calandrae and had arrived at the conclusion 

 that they were the same species. The type of -utihilis is a rather 

 small and poorly developed specimen. The national collection 

 contains a series of specimens taken at quarantine, Washington, 

 D. C., in a shipment of grain from Italy and determined by j. C. 

 Crawford as distinguendus Foerster. Comparison of tlu-sr 

 specimens with Hase's description leaves no doubt as to the 

 correctness of the determination. They also agree in every way 

 with the Howard and Tucker types.
