pean fauna do not occur in this country ; that is to say so far 

 as is known. Species of Anagrus are common here as are also 

 species of other common genera but I have never met with a 

 specimen which was similar to any of the European speci- 

 mens in my possession.* 



The new North American species which I shall call Anag- 

 rus spiritus is similar in all details of body structure, color, 

 antennae and wing ciliation to incarnatus but differs in the 

 following particulars : The marginal cilia of the posterior 

 wing's at the caudal margin are very long, the longest being 

 seven or eight times longer than the greatest width of the 

 wing blade, distinctly longer than in incarnatus in that 

 species only four or five times longer than the greatest width 

 of the wing blade ; otherwise the posterior wings are alike in 

 both species. In the American species the parapsidal furrows 

 are farther apart, in other words the mesoscutum is broader, 

 much broader cephalad than its width at the caudal margin, 

 the parapsidal furrows curving cephalo-laterad : in incarnatus 

 the parapsidal furrows are but slightly curved cephalo-laterad, 

 comparativelv straight, consequently the mesoscutum is nearly 

 rectangular but slightly broader at the cephalic margin than it 

 is broad at the caudal margin and distinctly longer than wide, 

 wedge-shaped. In spiritus it is only slightly longer than its 

 greatest width, its caudal margin curved, its shape peltate. In 

 incarnatus the caudal margin of this sclerite is nearly straight, 

 slightly concaved. The fore wings in both species are nearly 

 identical in shape, yet in spiritus they are slightly broader at 

 the apex, with the tendency to bear one more line of discal 

 ciliation (7 or 8 lines') and with longer marginal cilia. The 

 antennae in both are very much alike, yet in the female the 

 joints though similar in shape, yet are shorter in spiritus than 

 in incarnatus, so that the sixth funicle joint is barely longer 

 than the first ; whereas in incarnatus it is distinctly longer than 



*I may add that the differences between the species of Anagnis are 

 more subtle than those met with in any other group ; they are distinct 

 enough when once seen.
