EUMICRUS. 69 
E. concretus is apparently rare, most of the localities cited having yielded only a 
single example. 
13. Kumicrus palmatus. 
Rufescens, convexus, pube suberecta sat dense vestitus ; capite haud transverso; antennis clava fere bi-articulata, 
articulo nono sequente plus duplo majore, articulo quinto elongato. 
Long. 13-1 millim. 
Hab. Guatemata, Zapote (Champion). 
Antenne with the fifth joint elongate, nearly twice as long as the fourth, the seventh 
and eighth joints small, acuminate inwardly, the ninth transverse, not half so long as 
the tenth, the latter about as long as the acuminate eleventh joint. Head large, sub- 
quadrate, quite as long as broad. Thorax moderately narrowed behind. Elytra rather 
narrow, and without any humeral impression. ‘Tarsi unusually elongate. The male 
has the metasternum depressed along the middle, and the base of the front tarsi strongly 
dilated. 
Similar to E. concretus, but abundantly distinct by the structure of the antenne, the 
larger head, and the male characters. One pair only was procured. 
14. Eumicrus subnudus. 
Piceus, nitidus, parce breviterque pubescens ; antennis articulo quinto elongato, clava laxe tri-articulata ; capite 
nullo modo transverso, lateribus postice angustatis, vertice truncato. 
Long. 12 millim. 
Hab. Guatemaa, Senahu in Vera Paz (Champion). 
Antenne with the second and third joints subequal, the fourth joint slightly smaller, 
the fifth elongate, nearly twice as long as the sixth, the seventh and eighth joints minute, 
the ninth quadrate, the tenth rather larger, also quadrate, the terminal joint not elongate. 
Head considerably narrowed towards the vertex, the latter truncate. Thorax elongate, 
not much narrowed behind. Elytra rather broad, much broader from the shoulders 
towards the middle. Legs rather short and stout. 
We have received only one mutilated example of this very distinct species ; the 
posterior femora are remarkable on account of their very feeble clavation.
