8 PROC. ENT. SOC. WASH., VOL. 20, NO. 1, JAN., 1918 



The specimens from which the foregoing descriptions were 

 drawn, were obtained by the writer from a decayed tree-stump in 

 Crystal Lake Park, Urbana, 111., June 10, 1916. The imagines 

 emerged on various dates in the last week of June. The species 

 occurs commonly at Lafayette, Ind. (coll. Aldrich). 



No parasites were obtained. 



The larvae o'ccurred in groups of three or more in the slightly 

 moist wood and were evidently associated with the burrows of 

 coleopterous insects. They are very sluggish in their movements. 



Heteromeringia latifrons Loew. 

 Heteroneura latijrons Loew, Wien Ent. Monatschr., Vol. 4, p_. 82. 1860. 



Originally described from specimens obtained in the District 

 of Columbia. 



Johnson records it from the following states: Massachusetts, 

 New Jersey, Pennsylvania. Our collection here contains ex- 

 amples from Centerville, Urbana, and Mt. Carmel all in Illinois. 

 The dates of capture are June 1 and 18, July 3 and August 16. 

 One Urbana specimen was taken on the inner side of a window 

 in the basement of the Natural History Building of the University 

 of Illinois. I have seen specimens from Lafayette, Ind. (coll. 

 Aldrich) . 



This and the preceding species are doubtfully distinct. Wil- 

 liston's species valida differs from latifrons in having the wings 

 narrower, the inner cross vein before middle of discal cell, and the 

 dorsum of thorax and abdomen dark brown. His other West 

 Indian species of this genus, lumbalis, may be a synonym of 

 latifrons. I have seen specimens of both these species from the 

 collection of Professor J. M. Aldrich. They were taken in the 

 island of Grenada, W. I. 



Heteromeringia annulipes Johnson. 

 Heteromeringia annulipes Johnson, Psyche, Vol. 20, 1913, p. 99. 



Described from one specimen taken at Murfreesboro, Hart- 

 ford Co., N. C. No other published record. 



Heteromeringia nitida Johnson. 

 Heteromeringia nitida Johnson, Psyche, Vol. 20, 1913, p. 99. 



Originally described from three specimens obtained near 

 Long Branch, New Jersey, and not since recorded. 



There are two females, obtained in Illinois, in the Laboratory 

 collection, with the following data: Plainview, July 16, 1915, 

 on appletree (Flint), and Algonquin, July 12, 1897 (Nason).
