Notwithstanding the great elongation of the head in front of theeyes, I refer the unique insect represented in the upper figure tothe genus Opsomala of Serville rather than to his genus Mesops,because the antennae are inserted near the eyes, whereas in thelatter genus (which has much more the habit of Truxalis) the eyesare places assez loin des antennes, and because the same organsare not ensiform, thus assigning the insect to Servilles second divi-sion of Opsomala with the antennes co
