LATHYROPHTHALMUS. Sl 
Lathyrophthalmus myiatropinus, Spe/ser (1910). 
A very peculiar species, easily recognisable in both sexes by the 
pattern on the thorax and fourth abdominal segment. 
Dr. Speiser described the male from Kilimandjaro. The female 
is very similar; the middle of the frons is clothed with grey 
pollen, interrupted by a transverse moderately shining median band; 
thorax with the characteristic pattern ; second and third abdas 
minal segments with broad black hind borders, that on the third 
being the broader of the two, fourth segment entirely black, with 
the peculiar pattern seen in the male. 
Abdomen of the male more conical and narrower behind than 
in the allied species; genitalia rounded, black, with some black 
appendages below, but the fourth ventral segment is merely cleft, 
without the bilobate appendage exhibited by the preceding species. 
A male from Durban, Natal, 19. iv. 1892 (#. Muir) ; another 
from British East Africa, M’bagori’s Village, edge of Rednia Forest,
