LYGAUS. 2 187 
The markings of this species ally it to L. circumlitus, St8l, from which it differs by 
the much smaller size, unicolorous scutellum, the strongly pilose corium, and different 
markings, &c.

Lygeus rubriger, Stal, Stett. ent. Zeit. xxiii. p. 309. 200°. 
M. (Melanocoryphus) rubriger, Stal, En. Hem. iv. p. 113. 11°. 
Hab. Norta America, Carolina ?.—Mexico }, Vera Cruz 2. 
The type, in the collection of Dr. Signoret, is here figured. 
32. Lygeus lateralis. (Tab. XVIII. fig. 1.) 
Lygeus lateralis, Dall. List Hem. ii. p. 550. 58'. 
M. (Melanocoryphus) lateralis, Stal, En. Hem. iv. p. 118. 12”. 
Hab. Nortu America, Texas 2.—Mexico !2 (Mus. Berol.), Cuernavaca (Bilimek, Mus. 
Vind. Cees.). 
The specimen figured is in the Vienna Museum, which differs slightly from 
Mr. Dallas’s description in having the anterior margin and also the lateral angles 
red. These characters apply also to all the specimens which I have examined, and 
are in agreement with the description given by Stal? of examples in the Stockholm 
Museum. 
33. Lygeus vittiscutis. (Tab. XVII. fig. 14.) 
Lygeus vittiscutis, Stal, Stett. ent. Zeit. xxiii. p. 310. 203°. 
M. (Ochrimnus) vittiscutis, Stal, En. Hem. iv. p. 118. 14’. 
Hab. Mexico1? (Mus. Berol.), Orizaba (Bilimek, Mus. Vind. Ces.); GUaTEMALa, 
Capetillo (Champion); Nicaraeua, Chontales (Janson). 
This is a variable species. The Guatemalan specimens examined have the head 
luteous, with two black spots, thus bringing into doubt the generic value of the 
colour of the head relied upon by Stal. That this is not a southern characteristic 
is evidenced by a Nicaraguan specimen which agrees with typical Mexican forms, of 
which I have examined the type in the collection of Dr. Signoret, and also a typical 
specimen identified by Stal in the Stockholm Museum. In the Guatemalan specimens 
now before me the lateral black borders to the sternum and abdomen are very 
indistinct and almost obsolete. 
34. Lygeus consanguinitas, n. sp. (Tab. XVIII. fig. 12.) 
Head black; pronotum luteous, with two broad and somewhat fused transverse black faseis near anterior 
margin, from which proceed posteriorly two other gradually widening fascie of the same colour, which 
terminate near posterior margin, and are there outwardly angulated. Scutellum fuscous; a central line 
commencing halfway from base, apex, and lateral margins luteous. Corium fuscous; lateral and apical
