are similar. The mesoscutum in hrocheri is narrower than that in 

 armatus, about twice longer in proportion to its widtli caudad, in 

 armatus distinctly not twice longer than broad at its caudal margin. 

 Also on the scape, there are usually several more conspicuous setae 

 in the case of hrocheri. Thus it is not an easy matter to separate the 

 females of these two species structurally and it is not certain but 

 that coloration mary vary in hrocheri as it does in armatus (mostly, 

 however, to the pattern of its variety nigriventris Girault which still 

 has a bright yellow thorax). The males of booth species are similar 

 in antennal structure and thus no aid is given by this sex. 



The European species certainly will average in size but little 

 above armatus, if at all. Individuais of the latter vary considerably 

 in this respect. 



From the only European Species of Anagrus known to me — 

 incarnatus^) Haliday — hrocheri may be distinguished at once from 

 the fact that in the fem.ale antenna of the latter, the second funicle 

 Joint is distinctly much longer than the sixth, whereas in incarnatus 

 the opposite is true, the second funicle Joint distinctly shorter than 

 the sixth Joint of the funicle. Otherwise, the two species nearly agree, 

 espeoially in coloration; the Englisch species is lighter brown, however. 

 The fore wings are more pronouncedly curved in incarnatus. The 

 antennae of the male are similar in both species. 



Anagrus hrocheri is aquatic but shows no structural adaptations 

 for such a habit.

What appears to be a male of this species was sent to me by 

 Dr. L. 0. Howard, mounted on a slide with Aspidiotifhagus citrinus 

 (Craw.) from Fiji. However, this identification is based entirely on the 

 fact that the specimen has a distinct fuscous band across about the 

 middle of the wing (but much nearer to the venation than to the wing 

 apex); only the female of the species is known. This male specimen 

 differs from the description of the female in having most of the fla- 

 gellum black (excepting the somewhat lighter proximal funicle Joint), 

 its coxae are all black and only the cephalic legs yellow, the others 

 dusky. Its fore wings bear about twenty longitudinal lines of discal 

 cilia and are moderate in width, like those of enchenopae; their marginal 

 ciliation is moderately long, the longest about two-thirds the wings 

 greatest width; discal ciliation moderate. The first funicle Joint is 

 thrice the length of the pedicel and about a fourth shorter than the 

 following joints which are long, about six times longer than wide, 

 gradually shortening distad, the distal Joint subequal as usual to the 

 proximal Joint. The proximal tarsal Joint of posterior legs is very
