332 SUPPLEMENT. 



Twelve specimens. The costa of the wings is enlarged in the male. The base of 

 the femora and tibiae is yellow to a variable extent. 



3. Ommatius pilosulus. 



Emphysomera pilosula, Bigot, Ann. Soc. Ent. Fr. 1875, p. 243 \ 

 Emphysomera bicolor, Bigot, loc. cit. p. 244 2 . 



Hah. Mexico 1 2 , Acapulco, Amula, and Xucumanatlan in Guerrero (H. H. Smith), 

 Santiago Iscuintla in Jalisco (Schumann). 



Two males and nine females. I have little doubt of the correctness of the above 

 synonymy, notwithstanding very grave differences in Bigot's descriptions. The third 

 joint of the antennae is brown in both sexes and only about as long as the first. The 

 metanotum is opaque, yellowish on the sides. The abdomen is red or brownish-red 

 and varies not a little in the extent of the black markings ; there is no white on the 

 first segment ; the second segment is black in front and often has, as have all the rest, 

 a partial or entire black stripe in the middle. The hind femora are more thickened 

 than usual, but are not at all club-shaped ; they frequently have a blackish spot 

 on the outer side beyond the middle. This species must be allied to 0. peregrinus, 

 O. Sacken, who did not identify Bigot's insects. 



4. Ommatius parvus. 



Ommatius pumilus, Bellardi, Saggio etc. ii. p. 59 * (nee Macq.?). 

 Ommatius parvus, Bigot, Ann. Soc. Ent. Fr. 1875, p. 247 \ 



Hah. Mexico 2 , Chilpancingo, Tepetlapa, Amula, and Savana Grande in Guerrero 

 (H. H. Smith), Temax in Northern Yucatan (Gaumer), Cuautla 1 . 



Fifty-two specimens. The costa of the male is very slightly thickened and there 

 are some wrinkles in the cells behind it. This species is apparently the same as that 

 described by Bellardi 1 : 0. pumilus, Macq., has the tibiae wholly black. 



Note.— The manuscript of the foregoing pages (pp. 217-332) was for the most part 

 written in the autumn of 1896, and completed in 1899. I have been unable, in the 

 revision of these pages, to carefully study all the literature which has since appeared 

 on these families of insects. I trust, however, that nothing of importance has been 

 overlooked.— S. W. W.
