Hah. Fianarantsoa {Rev. W. Beans Cowan). Brit. Mus. 

 In the ' Annals & Magazine of Natural History,' vol. xv. 

 (1875) p. 414, I described a species, which I called Sagridola 

 quinqiiemaculata, from a female example. Mr. H. W. Bates, 

 in the ' Entomologist's Monthly Magazine' (xiv. 1879, p. 251) , 

 described an allied species (for which he also proposed a new 

 genus) under the name Anthrihola decor atus^ from an example 

 which he queries as a female. 



The species above described and the two species I have 

 just alluded to are all very closely allied, and are very simi- 

 larly coloured, although my S, quinquemaculata has the 

 yellow spots much more clearly defined. Having now the 

 sexes of two of the species, I am in a position to give charac- 

 ters by which all three may be distinguished, as follows : — 



A. quinquemaculata. — Of this species I have only seen the 

 female. It has no black subbasal band on the elytra nor spot 

 below the shoulder ; it has a quadrangular yellow spot at the 

 apex of each, not extending up the suture. The sterna and 

 legs are blackish brown, clothed with very short fine grey 

 pubescence ; the tibiffi are very slender ; the femora are only 

 moderately thick, and have no tooth below. The apical seg- 

 ment of the abdomen below is acuminate, very shining, 

 sparingly and very delicately punctured. 



The specimen which I mentioned as the male of this species 

 in the 'Annals' for March 1880 (p. 215) belongs to the 

 following species. 



A. decor ata. — This has a black subbasal band across the 

 elytra, sometimes interrupted, but leaving a black spot below 

 the shoulder ; the yellow at the apex forms a stripe on the 

 suture. Sterna and legs (except the inner part of the femora) 

 densely clothed with longer and coarser rusty-yellow pubes- 

 cence. The legs are much stouter than in A. quinquemaculata ; 

 the femora are more incrassate, with a small acute tooth 

 below (in both sexes) near the apex. The male has the 

 apical segment of the abdomen (seen from below) thickly and 

 distinctly punctured, truncated at the apex, and distinctly 

 concave. The female has this segment less acuminate than 

 in A. quinquemaculata^ and has the punctuation mucli more 

 distinct. 



A. femorata is a smaller insect, of a more uniform brownish 

 colour, with brown legs, with more prominent eyes, shorter
