EUMICRUS. 67 
7. Humicrus sallei, 
Major, robustus, convexus, brunneus, pubescentia parum elongata dense vestitus; antennis elongatis, articulo 
quinto valde elongato, clava elongata haud gracili ; elytris convexis, rotundulis ; tarsis majoribus. 
Long. 21 millim. 
Hab. Mexico, Cordova (Sailé). 
This is very closely allied to Z. brunneus, though a much larger insect; it is also much 
broader, and the pubescence of the elytra is denser and shorter. The head is broad, 
rounded behind. The antenne are elongate and stout, the club being especially long, 
with elongate terminal joint, and its first joint a little longer than broad; the fifth joint 
is also very long, and the third joint a little longer than the second or fourth, these 
latter being about equal in length. The tarsi in either sex are considerably longer and 
broader than they are in EL. brunneus. I have seen only three examples. 
8. Eumicrus bisphericus. 
Eumicrus bisphericus, Schauf. Mon. Scydm. p. 82'. 
Hab. Mexico, Teapa?. 
This species is perhaps allied to E. sallei; but, according to the description}, is larger, 
viz. 23 lin. long, and has the fifth joint of the antenna dilated in front. 
9. Humicrus commilitonis. (Tab. Il. fig. 22.) 
? Humicrus commilitonis, Schauf. Mon. Scydm. i. p. 84. 
Breviusculus, convexus, rufo-brunneus, pubescentia parum elongata minus dense vestitus, nitidus ; antennis 
abrupte clavatis, clava tri-articulata, articulo quinto parum, sexto haud, elongato ; capite fere circulari ; 
prothorace subgloboso, basi minus minute quadri-foveolata. 
Long. 13-12 millim. 
Hab. Mexico, Teapa!, Cordova (Sallé); Guatema.a, Cubilguitz, Pantaleon (Cham- 
pion); Nicaraaua, Chontales (Janson), Granada (Sallé); Panama, David, San Miguel 
in the Pearl Islands (Champion). 
Compared with the common £. brunneus this species is not only much smaller, but 
has a more robust thorax (broader near the front), with rather more conspicuous basal 
fover ; the joints of the antenne are all shorter, the club being more abruptly defined 
and with its first joint transverse; the pubescence is shorter and less erect; and the 
legs much shorter, the tarsi being quite short. The sexes are very difficult to distin- 
guish, the front feet of the male being scarcely dilated. 
E. commilitonis is apparently not common though widely distributed in our region, 
and apparently varies somewhat in accordance with its locality. Whether the species 
before me be really Schaufuss’s E. commilitonis is open to doubt; the brief description, 
however, of that writer contains nothing that disagrees with our insect.
