The injurious habits of this species have only, up t(j the present, 

 been noticed in Te-xas. A letter received from San Antcniio, represents 

 it as (juite annoying in a peach orchard, from its working into the fruit 

 and spoiling it just before its time of ripening. 



Distribution and Variations. 



Although not as yet recorded from the State of New York, it without 

 much doubt occurs within its limits, as it is found in Pennsylvania 

 and New Jersey, and has a broad distribution over the United States. 

 Mr. Uhler gives as its habitat, " Pennsylvania to I*"lorida, and west- 

 ward to Texas, Arizona and southern Colorado. Tiie western siteci- 

 mens are blacker and not so brightly red-margined as those from the 

 coasts of Georgia and Florida. In tlie sea islands of the latter a variety 

 occurs which is of a dirty sand-red. 



" The genus is essentially American, and ranges between the north- 

 ern warm-temperate zone and the southern warm-temperate zone. 'I'he 

 insular and equatorial ones of the lowlands are marked with yellow 

 spots, while the others are more uniform and plainer in their pattern." 



Its Appearance. 



It bears a marked resemblance to the common squash-bug, Anasa 

 tridis (De Oeer), Fig. 42, in size and form; the thorax is very nearly the 

 .same in shape. It measures one-half of an inch in length by one-fiflh in 

 breadth, is of a rusty black color, with the thorax and upper wings 

 freckled and broadly bordered with red. The brief diag- 

 nosis of Fabricius gives its characteristic features: "Oblong, 

 the thorax, margin of the elytra, and base of the femora 

 red." The diagnosis of De 

 Geer adds to the above, " ashy- 

 black, femora toothed in front."

 Tus-e^,ia7,le':i Fig.41. The Variety described 

 by Say, as inhabiting Mexico, 

 has the " surface paler, with numerous black 

 punctures, giving a dusky appearance; ori- 

 gin of the antennae and a line on each side 

 of the origin of the rostrum sanguineous." JL^-JS.^ f;rhaf/T\mrr- K
