ABEDUS.

(1871). 
The known species of this genus all inhabit Central America, one of them extending 
northward into the Southern United States. Four have been described, this number 
being here reduced to three. A. signoreti is a common insect within our limits. The 
metasternum is keeled, as in Deinostoma. The antenne are 4-jointed, the second and 
third very short, and each furnished with a long process, the third and fourth being 
sometimes fused into one. Montandon [Bull. Soc. Bucarest, ix. nos. 2 and 3, p. 11 
(1900)] treats Serphus and Pedinocoris as synonymous with Adedus, chiefly on account 
of the great similarity in general facies of the species of each of these genera and 
the difficulty in making out their antennal structure; but for the present it seems 
preferable to retain them as distinct. 
1. Abedus ovatus. (Tab. XXI. figg. 19, ¢; 19a, antenna.) 
Abedus ovatus, Stal, Stett. ent. Zeit. 1862, p. 461°; Mayr, Verh. zool.-bot. Ges. Wien, xxi. 
p. 404°; Uhler, Bull. U.S. Geol. & Geogr. Surv. i. p. 338%; Proc. Calif. Acad. Sci. (2) iv.

Stenoscytus mexicanus, Mayr, Verh. zool.-bot. Ges. Wien, xiii. p. 347, t. 11. figg. 6-10’. 
Hab, Nort America, Arizona and Texas 3, Lower California 4-—Mexico 3 (Mus, 
Holm.) ; Mus. Vind. Ces.5 ; Sallé), Xautipa in Guerrero (H. H. Smith), Jalapa (Hége). 
Of this species we have received six specimens from Mexico, including both sexes. 
The second and third antennal joints have each a moderately long process. We 
figure a male with the eggs still attached to the elytra. 
9. Abedus breviceps. (Tab. XXI. figg. 20, 2; 20a, antenna.) 
Abedus breviceps, Stal, Stett. ent. Zeit. 1862, p. 462°; Mayr, Verh. zool.-bot. Ges. Wien, xxi. 
p. 404, 
Hab. Mexico (Mus. Holm.'?), Cuernavaca (Lilimek, in Mus. Vind, Ces.*). 
Very like A. ovatus, but with the head less produced in front and the membrane a 
little more developed. The type, a female, has been lent me by Dr. Aurivillius; it 
has the elytra less dilated at the sides than in A. ovatus, and the antennal processes as 
long as the apical joint.
