2. Aphilanthops punctifrons. (Tab. VII. fig. 2.) 



Niger ; facie, maculis thoracis, lineis abdominis, pedibusque flavis ; alis fumatis ; flagello subtus pallide fulvo ; 



area cordiformis punctata. $ . 

 Long. 15 millim. 



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



Eyes diverging beneath. Ocelli in a triangle, separated from the eyes by the length 

 of the third antennal joint, and from each other by the length of the fourth. Clypeus 

 but very slightly convex ; the apex produced, rounded, projecting outwardly ; the 

 lateral margin fringed with long yellow hair. Front and vertex rather strongly punc- 

 tured ; the face and oral region not so strongly and more sparsely. Antennal tubercle 

 broad, furrowed in the middle, dilated below the antennae, reaching to the base of the 

 clypeus. The head is clothed with short pubescence ; the face sparsely covered with 

 silvery hair. The face, oral region, cheeks, inner orbits of the eyes to the top of the 

 antennal tubercle, the antennal tubercle, and the mandibles (except the apex and the 

 edges of the latter and a spot behind the top of the eyes), yellow ; the apex of the 

 clypeus black, Thorax punctured ; the punctures above sparse, at the sides much 

 closer and coarser ; on the scutellum and metanotum the punctures are more widely 

 apart than on the mesonotum. The heart-shaped area of the median segment with 

 large scattered punctures, except on the centre, which is furrowed. Apex of the 

 median segment obliquely rounded. A spot on either side of the pronotum, the 

 tegulae, a spot on the pleurae below them, a spot on either side of the scutellum, a 

 broad elongated line on the sides of the median segment, and two spots on the heart- 

 shaped area at the base, yellow. Abdomen longer than the head and thorax united ; 

 blunt at the base and apex, irregularly covered with large punctures ; the second, third, 

 and fourth segments with a transverse depression at the base and apex. Pygidial area 

 irregularly reticulated, opaque, the sides margined, broader at the base than at the 

 apex, the latter rounded, the sides with large punctures ; the lateral fringe moderately 

 long, golden-fulvous. Incision in the hypopygium reaching to the middle of the 

 segment, rounded at the base and not much narrowed there ; the segment depressed 

 on either side of the incision. The second ventral segment is depressed on the apical 

 half, the basal part being considerably higher than it, margined at the base, the margin 

 being continued out from the middle as a short stout triangular keel. There is a 

 broad interrupted yellow band on the first abdominal segment ; a narrower continuous 

 one on the second (widest at the sides), a still narrower, interrupted one on the third, 

 and an elongated mark on either side of the fourth and fifth segments. All the legs 

 are yellow in front, except on the hinder trochanters. The first recurrent nervure is 

 received about the length of the top of the second cubital cellule from the. first trans- 

 verse cubital nervure ; the second is interstitial.
