Examples of this species have been sent home by Mr. Champion from Guatemala. 
As Prof. Uhler remarks, it is the most closely related to A. calcaratus, Linn., of 
Europe; “but in all the specimens of the European insect which I have yet seen the 
collum of the prothorax is very short, and the disk of the pronotum more robust and 
flattened than in our species.” I have, on the authority of the same writer, placed 
A. ater, Dall., as the female and therefore synonym of this species. Townend Glover, 
evidently deriving his information from the same source, states that A. eurinus “ occurs 
in late summer and autumn, sometimes in great numbers, on golden-rod and other 
herbaceous plants growing rankly near the edges of woods, also on Rhus glabra 
(smooth sumach).” 
2. Alydus femoralis, n. sp. (Tab. XV. fig. 9.) 
Ochraceous, pilose, mottled and punctured with brown. Antenne ochraceous; first, second, and third joints 
subequal ; fourth longest, somewhat incrassated, black, with the base broadly luteous. Head with the 
lateral margins from eyes to insertion of antenne, and a central longitudinal line, pale ochraceous ; 
between eyes and surrounding ocelli transversely black. Pronotum with the lateral margins and a faint 
central longitudinal line pale ochraceous ; lateral angles moderately produced, apices fuscous. Scutellum 
very coarsely punctate, with the apex paler. Corium with the lateral margin pale ochraceous; inner 
apical margin sanguineous. Abdomen above black ; connexivum with a row of subquadrate luteous spots. 
Underside of the body very pale ochraceous; head beneath with the lateral margins, a central longitudinal 
line, and two linear and elongated marks on each side at base black. Sternum with the disk blackish ; 
the lateral margins coarsely punctate, with a double series of obscure fuscous linear spots (in some speci- 
mens these are barely visible), Abdomen punctate, a double series of transverse black spots on disk of 
second segment, a single series of the same at base of third segment, and a prominent black spot on each 
side of disks of remaining segments. Legs pale ochraceous, spotted with fuscous; posterior femora with 
the apical halves fuscous, annulated with ochraceous; rostrum ochraceous, with the apex pitchy. Posterior 
femora armed with about four strong black spines. 
Long. 11-12 millim.

This species appears to belong to the subgenus Megalotomus, Fieb., and to be allied 
to A. (Megalotomus) pallescens, Stal.
