EURYSTHEA (p. 29; to follow the genus [roneus). 
Eurysthea, Thomson, Class. des Ceramb. p. 247. 
Euristhea, Lacordaire, Gen. Col. viii. p. 321. 
An exclusively Tropical-American genus, of which about half a dozen species are 
known. 
1. Eurysthea cribripennis. (Tab. XVIII. fig. 5.) 
Angusta minus convexa, setis griseis incumbentibus et erectis vestita, castaneo-fusca, antennis pedibusque 
fulvescentibus, elytris utrinque fascia mediana transversa valde angulata (circumflexiformi) maculisque 
rotundatis duabus prope apicem (altera juxta suturam, altera, interdum minus distincta, marginali) 
testaceo-fulvis ; thorace callis nitidis quinque (uno elongato dorsali alteris utrinque duobus interdum fere 
conjunctis), interstitiis sparse grosse punctatis, plus minusve fulvo-aureo tomentosis ; elytris confertim sed 
discrete (apicem versus subtilius) punctatis, apice transversim truncatis, angulo exteriori longe spinoso. 
Antenne 3 @ articulis 3°-4™ apice unispinosis, supra, ¢ valde, 9 vix perspicue, carinatis. Thorace spina 
laterali, ¢ brevissima, ? elongata et acuta. Femoribus posticis gradatim incrassatis, nec tumide clavatis. 
Long. 7-10 lin. ¢ @.

This would be a Mallocera, Sect. 2, according to Lacordaire’s definition; but it is 
clearly more closely allied to Eurysthea obliqua than to the type of Mallocera. It 
differs from Eurysthea in the spined antenne and the less clavate hind femora. Further 
material is required to test the generic validity of these characters. I suspect they are 
variable, having before me an allied species in which some examples have only the 
third joint spined, and others both the third and fourth. 
SPH ZRIONILLUM. 
Corpus minus elongatum, sparse longe setosum. Oculi minus grosse granulati. Palporum articuli terminales 
angustius triangulares. Antenne sat breves; scapo quam articulus tertius haud breviori, articulis 3°-8™ 
unicarinatis (nec suleatis) apice unispinosis. Thorax sat late rotundatus, inermis, dorso quali. Elytra 
picta, punctis grossis et sparsis setiferis exceptis levia, apice truncata et spinosa. Femora clavata et 
pedunculata, apice brevissime bidentata ; tibiee intus et extus carinate. Acetabula antica et intermedia 
clausa. Mesosternum latum sat convexum. 
A group of small species, differing greatly from the rest of the Spherionine in general 
form and colours. In their style of elytral markings they resemble Stenygra and the 
allied genera ; but their true affinity appears to be in the direction of Spherion, with 
which they agree in all structural characters, except the rather more finely facetted 
eyes and less securiform palpi. 
1. Spherionillum pictum. 
Nigro-piceum, nitidum, sparsim (apud elytra seriatim) griseo-setosum, thoracis corporisque subtus lateribus 
argenteo-tomentosis; antennis, tibiis et tarsis rufo-castaneis ; elytris utrinque maculis magnis quadratis 
tribus fulvo-testaceis, 1° juxta scutellum, 24 et 3° lateralibus ante et post medium, illa per marginem 
incrassatum usque ad humerum continuata; thorace lato, suborbiculari, sparsissime punctato; elytris 
apice flexuoso-truncatis, angulo exteriori breviter spinoso, ' 
Long. 53 lin. ¢ @. 
Hab. Mexico, Playa Vicente, Cordova (Sallé). 
Named Spherion pictum, Chev. (MS.), in the Sallé collection. In the male the 
antenne are a little longer, in the female a little shorter, than the body.
