the male much larger, longer than wide, and distinctly longer than the 
prothorax, equal in width to the latter and but very slightly narrower 
than the head, similarly punctured. Length 10.0 mm.; width 1.8 mm.

Legs shorter and relatively stouter, pale honey-yellow throughout, the 
femora abruptly black in outer third. Body much smaller than in the 
preceding species, stout and strongly convex, similar in coloration and 
polished lustre; head in the male a little wider than the prothorax or 
elytra, the sides converging and circularly arcuate behind the eyes to 
the neck, similar in the female but subequal in width to the prothorax 
and narrower than the elytra; eyes at one-half more than their own 
length from the base; prothorax scarcely longer than wide, oval, 
rounded at the sides, the latter strongly converging posteriorly as 
usual; elytra quadrate and scarcely longer than the prothorax in the 
male, notably longer in the female. Length 6.8 mm.; width 1.25 mm.

Legs nearly as in riparius but entirely clear honey-yellow throughout, 
without trace of darker ornamentation. Body similar to that of 
riparius but still smaller and slightly more slender; head with only very 
slight sexual differences, distinctly wider than the elytrain the male 
and only just visibly so in the female; eyes moderately convex and 
prominent, at about a third more than their own length from the base, 
the sides behind them strongly converging and circularly arcuate in 
both sexes; prothorax scarcely visibly longer than wide, obtrapezoidal, 
the sides broadly arcuate, a little more rounded anteriorly; elytra not 
quite as long as wide or as long as the prothorax in either sex, 
coarsely, sparsely punctate, the sides feebly diverging from the base 
and broadly, feebly arcuate; abdomen subequal in width to the elytra.

It is rather remarkable that the European riparius should 
occur within the United States, but two males collected in 
the Caucasus and forwarded to me by Mr. Reitter, agree in all 
respects — allowing for sex — witha single female in my 
cabinet taken at an unrecorded locality in Texas. If it was 
collected in the neighborhood of Galveston, there is a strong 
probability of its being simply an adventitious importation, 
and, that it has established itself in America, is by no means 
proved. The Mexican mexicanus Er., is listed by Henshaw, 
but I have seen no examples taken within our borders; it has 
the coloration and facies of grandis but is much smaller, 
with the antennae and legs rufous, the tip of the posterior 
femora alone black. Our speciesare all alate and with dis- 
tinct elytral humeri.
