in the ovipositor; dissimilis shows a general resemblance to 

 these in form, while albipalpus is very distinctive ia size, form 

 and general coloration, sbowingp in fact, a decidedly closer gen- 

 eral superficial resemblance to one spedes of Sonth American 

 Cyrtoxipha {guycnnensis Sausstire). 



Wlien compared with Nemobius. the spedes of the present 

 genus show other diflFerences besides those of the innament of 

 the caudal femora; in the greatly reduced apical area of the 

 male tegmina and the greater divergence of the two axillary 

 veins ; in the wholly absent or very greatly reduced t^imina in 

 the females of several spedes, and in the ovipositor, which in 

 .some of the species is wholly unarmed. 



But one spedes. Hygronrmobius aUeni. g eno t ype, ts known 

 from within the boundaries of the United States, having been 

 recently found by us in extreme southern Florida.

Nearest in relatioaship to H. Hmra. the present species may 

 be readily separated, particulariy in the female sex, by the 

 characters given in the accompanying key. The original de- 

 scription is excellent but the minute lateral tegmina of the 

 female were unfortunatdy overlooked.* 



In addition to that portion of the typical series which has 

 not been destroyed, we have had before us the following series, 

 found' Mack soil and amm^ drift in a mangrove swamp 



near Ni tlorida. At h^ tide this area was mder more 



than a foot of water. The series was taken when the tide 

 was out, after long and bborious search; at the time the 

 weather was cool and the individuals were not rapid in their 

 movements, but were difficult to capture owing to the environ- 

 ment, their sombre coloration and thdr habit of hiding under 

 the drift or the sodden mangrove leaves. About the same 

 time, however, a species of Nemobius was found in a similar 



5. At the tioK the icncric dcsc ri pt i oa was written, both adult females 

 of die typical seriet nad been destroyed and it was then supposed that 

 the dsscription of this tex was based on spe c i m ens in the tnstar pre- 

 ceding maturity.
