SP1LSK0PHTHALMA. 355 



This species agrees generally in coloration with S. sicheliana, but may be easily known 

 from it by the longer head and shorter thorax; the third antennal joint nearly twice 

 the length of the fourth (in 8. sicheliana it is not much more than one-half longer), 

 the slope of the median segment more abrupt, and the second segment of the abdomen 

 without two small patches of yellow pubescence, its apex broadly covered with white 

 pubescence, which extends triangularly beyond the middle. 



76. Sphserophthalma temaxensis. 



Nigra; capite, pronoto, maculis 2 metanoti, abdominis basi segmento 2° maculis 2, segmentisque 3°-6 m 



argenteo-pilosis. $ . 

 Long. 11 millim. 



Hab. Mexico, Temax in North Yucatan (Gaumer). 



Head subquadrate, almost transverse in front, rounded behind, densely covered with 

 pale ochraceous pubescence, the antennal tubercles and the base of the mandibles 

 reddish. The antennae black ; the scape with long white glistening hair ; the third 

 joint hardly one-quarter longer than the fourth. The thorax twice the length of the 

 head, the base almost transverse, the apex with a semioblique slope ; from the middle 

 it becomes gradually narrowed to the apex. The sides of the mesonotum are very 

 strongly punctured ; the base has a band of pale fulvous hair ; on the apex are two 

 elongated marks (narrowed towards the apex) of pale pubescence. The mesopleurse 

 are covered with long white hair ; the metapleurse with large deep round punctures. 

 The abdomen is black, longer than the head and thorax united, and is sharply narrowed 

 from the middle to the apex ; the basal segment becomes wider towards the apex, is 

 coarsely punctured, and bears long white hair, the extreme apex having a band of pale 

 fulvous pubescence ; the second segment has two roundish marks of white pubescence 

 at the base, the apex being banded with white pubescence, except in the middle ; the 

 segments 3-6 are densely covered with white pubescence, except in the centre. The 

 pygidium is finely longitudinally striolate, and fringed laterally with long fuscous hair ; 

 the apex is not incised. The basal ventral segment has a not very distinct keel ; the 

 second ventral segment bears scattered punctures, and is sparsely covered with white 

 hair ; the other ventral segments are densely covered with white hair ; the hypopygium 

 is rufous, bare, finely transversely striated. The legs are black and covered with white 

 hair ; the spines and calcaria are black.
