In a typical Mexican specimen forwarded to me from the Stockholm Museum, the 
pronotal markings are red; in a Guatemalan specimen (here figured) the anterior 
pronotal margin is luteous, whilst in two specimens from Mexico contained in the 
Berlin Museum all the markings are luteous. These forms probably define the 
limits of variation in the species. 
11. Lygeus bilimeki, n. sp. 
Black; a spot at base of head, margins of pronotum and a central fascia, terminating about halfway from 
base, inner and apical claval margins, lateral and apical margins to corium red. Membrane fuscous, 
apical margin pale luteous. Buccule, anterior margin of prosternum, acetabula, and posterior margins of 
pro-, meso-, and metasternum luteous. Segmental incisures very faintly and obscurely dull reddish or 
luteous. Rostrum black, not quite reaching posterior coxe. Antenne wanting. 
Long. 8 millim. 
Hab. Mexico, Orizaba (Bilimek, Mus. Vind. Ces.). 
This species is closely allied to Z. uhleri, from which it differs by the black 
abdomen &c. 
Orificia entirely or towards the apices pallid. Ocurostomts, Stal. 
12. Lygeus guatemalanus, n.sp. (Tab. XVIII. fig. 2.) 
Body above black. Head somewhat thickly pilose, with a small pale and very indistinct spot at base. Pro- 
notum with the anterior and posterior margins narrowly and obscurely, the lateral margins broadly, a 
central longitudinal fascia which faintly reaches anterior margin, but which is connected near its apex to 
lateral margins by a transverse fascia, lateral margins of corium (broadest at base), apex of scutellum, 
and anterior and apical margins of clavus narrowly, luteous. Membrane glossy black, apical margin very 
pale luteous. Underside of head, antenne, rostrum, sternum, and legs black; lateral margins of sternum 
broadly luteous; anterior and posterior margins of prosternum, and posterior margin of mesosternum, and 
anterior acetabula narrowly and obscurely luteous. Intermediate and posterior coxe and abdomen 
ochraceous, the last with the apical segment and a marginal streak on the penultimate segment black 
(on the fourth segment there is also a fainter indication of the same). 
Long. 7 millim. 
Hab. Guatemata, San Gerénimo (Champion). 
This species is allied to L. whleri, Stal, from which it can be at once distinguished 
by the different markings of the pronotum and corium. The pronotum is also deeply 
impressed at the transverse luteous fascia. 
We have received but one specimen from Mr. Champion.
