SUPPLEMENTARY NOTE ON THE ANTHOMYIID GENUS 

 PHYLLOGASTER (DIPTERA). 



BY J. R. MALLOCH, URBANA, ILL. 



Since sending my paper, on the genus Phyllogaster, which ap- 

 peared in Can. Ent., XLIX, p. 227-228, 1917. I have read 

 C. W. Johnson's paper in the April number of the same volume, 

 in which he describes a new species of this genus under the 

 name rohustus. An examination of paratypes of robiistus dis- 

 closes the fact that in addition to the difference in size between 

 the species and cordyluroides the male may readily be separated 

 from the latter and also from littoralis by the presence of a large 

 number of strong bristles on the basal dorsal segment of the hypo- 

 pygium (two in the others) and the much larger pulvilli which 

 exceed in length that of the apical tarsal joint, whereas in the others 

 they are much shorter than it. The female of rohustus iias two 

 thorns on apical abdominal segment, littoralis has four, the female 

 of cordyluroides is unknown to me. As in cordyluroides the third 

 vein of the wing is bare in rohustus. 



THE GENUS HADRONEMA UHL. (MiRID.^; 

 HETEROPTERA.) 



BY EDMUND H. GIBSON, U. S. BUREAU OF ENTOMOLOGY. 



The flower bugs of the genus Hadronema Uhl. constitute an 

 interesting little group closely allied to the genus Lopedia Uhl. 

 species of which are known to most collectors of insects, such as 

 the common Phlox bug. Those of Hadronema may be distinguished 

 from the species of Lopedia by the fact that the base of the ^•ertex 

 is strongly carinate across its whole width. 



Most of the species are of western occurrence, though, mili- 

 laris Uhl., the haplotype of the genus, is distributed over the entire 

 United States and Southern Canada. Little is known of the 

 economic importance of the species, and in all probability they are 

 but little restricted in food preferences. 



The genus belongs to the division Loped iaria \'an D. of the 

 tribe Orthotylini Van D. and was characterized by I'hler as fol- 

 lows: Aspect of Lopus, cranium somewhat con\-ex, face almost 

 vertical, eyes prominent, oval, almost vertical: occiput with a
