This is apparently a rare insect, represented in our collections by one or two examples 
from each locality. Our figure is taken from an example found at Pantaleon. 
4. Xantholinus strigiceps. 
Nigerrimus, nitidus, minus depressus; antennis pedibusque piceis ; capite striguloso, tantum punctis impressis 
paucis; thorace absque seriebus discoidalibus, utrinque versus angulos posteriores tripunctato ; elytris 
quam prothorax paulo brevioribus. 
Long. 10-11 millim. 
Hab. Nicaragua, Chontales (Janson). 
Head a good deal narrowed in front, covered with fine longitudinal striz, which are 
wanting, or at any rate more scanty, on the disc, and on the underside are very regular and 
definite ; with two punctures behind the eyes, and three others forming a distant series 
nearer the middle. Thorax a little narrowed behind. Elytra rather shorter than the 
thorax, somewhat coarsely but scantily punctate, with a discoidal series of coarser 
punctures. 
This is a very distinct species from any other ; it has no carina on the prosternum, 
and the second and third joints of the antenne are rather elongate.
