Three extra-European genera at present exist—one, according to present knowledge, 
confined to the Nearctic Region, one principally Palearctic, but also recorded from 
North America, and the other probably cosmopolitan, and represented in this fauna.

The position of the posterior acetabula, “leviter distantibus,” and the unarmed 
anterior femora are the strongest differential characters of this genus, the distribution 
of which, as we have previously remarked, is probably cosmopolitan. 
One species is at present here alone enumerated. This is evidently an inadequate 
return; for doubtless many more exist. A Mexican one in the collection of the Berlin 
Museum has passed through my hands, so closely allied to MW. simulans, Stal, from 
Buenos Ayres, that I did not feel justified, without the examination of a series of 
specimens, either in identifying it as that species or describing it as new.

There seems to be some confusion as to the habitat of this species. Although “ Insula 
Taiti” is twice given by Stal (see supra), he, however, records a single specimen from 
Honduras sent by Dom Hjalmarson!, and also enumerates both male and female in 
his ‘Hemiptera Mexicana’*. A Mexican specimen in the Berlin Museum seems to 
agree well with Stal’s description. 
Subfam. CY MINA. 
Cymida, Stal, Hem. Afr. ii. p. 121 (1865). 
Cymina, Stal, En. Hem. iv. p. 123 (1874). 
Cymine, Uhler, Bull. U.S. Geol. & Geog. Surv. iii. p. 409 (1877). 
This subfamily of the Lygzide is recognized by the hemelytra being wider than the 
abdomen. It has been divided into two divisions.
