68 SCYDMENIDE. 
10. Eumicrus ——? 
Hab. Guatemata (Sallé). 
This insect is represented by a single female, which I fail to reduce to either 
E. brunneus or E. commilitonis, though in many respects it appears intermediate. 
11. Eumicrus brevipes. (Tab. II. fig. 23.) 
Latiusculus, rufo-brunneus, pube minus elongata dense vestitus; antennis articulo quinto mediocriter, sexto 
nullo modo, elongato, clava abrupta, sat elongata ; prothorace minus gracili ; elytris rotundulis. 
Long. 2 millim. 
Mas tarsis anterioribus fortiter dilatatis. 
Hab. Guatemata, Las Mercedes, Capetillo (Champion). 
This species is rather smaller than E. drunneus; and has short antenne, the fifth 
joint being, however, very elongate, while the sixth is quite small and transverse, and 
scarcely larger than the very small seventh and eighth joints, the third and fourth 
joints are each smaller than the second, and the first joint of the club is slightly longer 
than broad. | | 
Although we have received only a single male of E. brevipes it is evidently a distinct 
species from E£. brunneus and E. commilitonis. The single female comes from Las 
Mercedes, and though it has the front tarsi a little dilated is, I feel sure, that sex of 
E. brevipes, and not the male of a different species. 
§ 2. Thorax completely destitute of basal fovee. 
12. Eumicrus concretus. (Tab. II. fig. 24.) 
Elongatus, angustulus, convexus, rufescens, antennis pedibusque testaceis, pube depressa sat elongata tenuiter 
vestitus ; capite truncato, subtransverso; antennis gracilibus, clava elongata, tri-articulata, sat abrupta, 
articulo nono gracili, fere quadrato. 
Long. 14 millim. 
Hab. Guatema.a, El Reposo, Cerro Zunil, San Isidro, Pantaleon, Zapote, San Gerd- 
nimo, El Jicaro, San Juan in Vera Paz (Champion); PANAMA, Volcan de Chiriqui 
2000 to 3000 feet (Champion). 
Antenne rather slender and small, with elongate club ; second joint twice as long as 
the third, fourth and fifth joints about equal, the latter a little the longer, though not 
so long as the second, the sixth small, the seventh and eighth very small, the ninth 
considerably smaller than the tenth, not transverse, the tenth also about as long as 
broad. Head rather short and broad, truncate behind. Thorax with its greatest width 
near the front, much narrowed behind. Elytra narrow, without any depression at the 
shoulders. I do not detect any sexual characters. This insect I expect will prove to 
be allied to E. annulicornis, Schauf. ; but as that species is from the Amazon valley, and 
is described as having somewhat different pubescence, no doubt the two are distinct.
