376 Mr. P. Cameron on neiv Species of 



Black ; two large marks on the side of the second abdo- 

 minal segment and the fourth and fifth entirely dull orange- 

 yellow ; the wings smoky, the base, apex, and a cloud behind 

 the stigma whitish hyaline. 



AntennEe short, tiiick, covered with an obscure microscopic 

 pile, the base and apex of the scape piceous beneath. The 

 apical half of the mandibles piceous. Above the antennae 

 the head is densely covered with golden pubescence, barer in 

 the middle, but this may be owing to it having been rubbed 

 off. The eyes curved, slightly converging towards the bottom. 

 The hinder ocelli are separated from each other by the same 

 distance they are from the eyes. The yellow-golden pile oq 

 the mesonotum extends to the base of the scutellum ; in front 

 the mesonotum is much barer, probably through being rubbed. 

 The scutellum is covered with a dull brownish down. The 

 median segment is clothed with a short pale golden pubes- 

 cence, especially on the middle above; behind, it is hollowed 

 slightly and in the middle is not so thickly haired as on the 

 sides. The pro- and metapleurse are covered closely with a 

 short, the mesopleurje with a still shorter, pale golden pubes- 

 cence. Abdomen shining, pruinose ; the marks on the second 

 segment are at the base at the sides and extend to the 

 middle; the fourth and fifth segments are only orange-yellow 

 above ; the base of the sixth segment is orange in the middle. 

 The femora and tibite are densely pruinose, appearing greyish ; 

 the tarsi are bare. The recurrent nervures curve towards 

 each other above, the first having a broader curve ; the third 

 transverse cubital nervure is obliterated entirely, but both the 

 recurrent nervures are present, the first being received shortly 

 before the middle of the cellule. 



Near P. pictus^ Kohl. 



Fam. Mutillidae. 

 Sph^rophthalma, Blake. 



Splicerophthalma posticata^ sp. n. 

 Long. 11 millim. 



Hah. Mexico, Chilj)ancingo in Guerrero {H'oge). 



Allied to S. pallene, Cam., from Durango, but differing 

 from it in having the black on the anterior part of the abdo- 

 men not continuous at the base, the black being triangularly 

 narrowed in front and ))roduced into a sharp pi)int (instead of 

 being incised) at the apex. The shape of the abdominal 

 black mark is very like that of iS. toluca, Blake, but that 

 species differs from the present insect in many other respects.
