Callus slightly convex, moderately long, with one f oveole ; posterior 

 lobe short ; first joint of antennae long and not much thicker than 

 three ; length 4-6 mm anthracina 



L. crassicornis (Uhler).

This species is given by Van Duzee as occurring in New Hamp- 

 shire. It was originally described from the Saskatchewan River, 

 in the Canadian Northwest, and Hungerford records it from New 

 York. It may, or may not, be found in Connecticut, eventually. 

 L. anthracina Uhler.

Our common shining black Saldid, to which I suspect all Eastern 

 records for the preceding and following refer, if, indeed, it should 

 not eventually turn out that coriacea following is only a dimorph 

 of this brachypterous species. So far, it is unreported from 

 Connecticut. 

 L. coriacea Uhler. 



Rept. U. S. Geog. Surv., 421, 1871. 



The remarks preceding cover this species, reported thus far 

 from all the States bordering on Connecticut. The two last species 

 are placed by Van Duzee in the genus Salda. 



Orange, 4 June, 1910 (B. H. W.). 



In conclusion, it cannot be too much emphasized that if there 

 are few Connecticut records of this interesting group, it is merely 

 because they have not been collected. In one summer, any indus- 

 trious collector should be able to get at least eight or ten of the 

 species mentioned in goodly numbers, even though he work in a 

 restricted locality. 



It may also not be amiss to remark that the genera Chiloxanthus 

 Renter and Chartoscirta Stal, are both found in America, and 

 careful collecting may turn them up in the East; the same is 

 equally true of the other genera, for there are few insects so 

 widespread as the genera and species of water bugs and their 

 allied littoral forms. 



Family VELIIDAE. 



By J. R. DE LA TORRE-BUENO. 



The family Veliidae contains three genera which may be 

 separated as follows : 



Key to Genera. 



1. Anterior tarsi, each with more than one joint 2 



Anterior tarsi one-jointed; intermediate tarsi longer than pos- 

 terior, third joint split, with feathery hairs in cleft

2. Anterior tarsi two-jointed ; last antennal joint longest ^ 



Microvelia, p. 419 

 Anterior tarsi three-jointed; intermediate tarsi longer than pos- 

 terior; feathery hairs and cleft wanting; first antennal joint 

 longest Velia, p. 417
