turn is more transverse, the anterior submargin being wider in 

 diameter than the width of head across eyes; first segment of an- 

 tenna shorter, barely exceeding tykis and less than half the length of 

 basal segment of rostrum. 



Aphanus umbrosus and illuminatus Dist. 



Dr. Horvath was undoubtedly correct in suggesting (Ann. Mus. 

 Nat. Hungar., 561-562, 1908) that Distant's pale legged var. illumi- 

 natus was a distinct species from his more common widely distributed, 

 all black form — umbrosus. While the latter species is pretty gen- 

 erally distributed over the entire United States except possibly the 

 extreme northern areas, the former seems to be confined to the ex- 

 treme southern part of the country. I have examined a male of this 

 in the collection of the U. S. N. M. from Buck Key, Fla. (G. Brainard 

 collector). It differs from umbrosus as follows: the lateral edge of 

 the pron'otum more sharply impressed, the posterior lobe and the an- 

 terior lobe of the pronotum except the central disk more closely and 

 coarsely punctate, first and apical part of second segment of antenna 

 (third and fourth broken off), rostrum and legs, ochraceous. Uhler 

 commonly referred to Aphanus umbrosus as Microtonia carbonaria 

 Rossi which is a synonym of airata Goeze. 



It is just as well to leave these in the genus Aphanus as placed by 

 Horvath in the above named paper, but there is some question in my 

 own mind but what Distant was correct in making these the bases 

 for a new genus (Dorochosa) which, because of its preoccupation, 

 was later changed to Delochilocoris by Dr. Bergroth. 



Microtoma atrata Goeze. 



I have omitted the above from my key to the Rhyparochromini 

 and I include it in our fauna with some doubt as I have only seen 

 one specimen of it in Uhler's collection (U. S. N. M.). But if 

 Uhler's locality datum is correct this species should be accredited to 

 the United States, for this single male specimen of this species is 

 plainly labelled R. I., undoubtedly meaning Rhode Island. I have 

 carefully compared this with European specimens in my own col- 

 lection and there is no question of its identity. We cannot altogether 

 trust Uhler's published records for this species as we know that he 

 applied the above name or M. carbonaria Rossi to American speci- 

 mens of A. umbrosus Dist., a much smaller species.
