No. 34-] UEMIPTERA OF CONNECTICUT I VELIIDAE. 42I 



any of the other species, as it is the largest of our Eastern forms, 

 except americana, from which its sHm body, long thin antennae 

 and white-spangled hemelytra at once distinguish it. The apterous 

 form is more glabrous and much less velvety in appearance than 

 the winged forms. In addition to the original locality, and from 

 the other states already mentioned, it is known from Georgia, 

 where it was taken by Dr. J. C. Bradley. 



This species has not been recorded from Connecticut.

This is the species that has appeared in the writer's papers as 

 pulchella Westwood, from which it may be separated, aside from 

 other characters, by having the first antennal joint longer than the 

 second. It is also smaller, and pulchella, so far as is known to me, 

 is only Antillean in distribution. This tiny bug is perhaps the 

 most abundant of our native Microvelias, and it may always be 

 found in large colonies on the matted Lemna or duckweed on still 

 ponds. It is just as predaceous as its larger congeners and is most 

 frequently found in the wingless form, although the fully winged 

 is not rare. It begins to breed in the spring and lays its tiny eggs 

 on the underside of the duckweed leaves with the head end toward 

 the edge of the leaf, in the usual gelatine. The nymphs emerge 

 in eight to thirteen days, and after four molts reach the adult stage 

 in about sixteen days minimum, twenty- four days from the ^gg 

 to the adult, which would allow for eight generations in the course 

 of the summer. As one female may lay several batches of eggs, 

 her progeny may be found in various instars at the same time. 

 Attention is directed to the unusual number of molts, as the 

 general rule in all Heteroptera is five, which in the known instances 

 of deviation has been exceeded, but not lessened. 



No Connecticut records are available.

No Connecticut records are at hand for this species, newly 

 described from northern New York.

This minute species, described originally from Ohio, was later 

 found by Prof. H. M. Parshley in Northampton, Mass., and by 

 myself in great abundance in White Plains, N. Y. It is so tiny 

 a species it can easily be mistaken for a nymph of borealis, particu- 

 larly since the two species are commonly found in company in 

 secluded coves and shallow waters.
