SIMOTDES. LATHrKOPHTHALMUS. 77 



The species is also widely distributed in the Ethiopian Region, 

 but seems to be very often confused with some other species 

 belonging to the preceding genus. In the collection there are two 

 males and two females from Durban, 1902 (F. Muir} ; Salisbury, 

 S. Rhodesia (Gr. A. K. Marshall) ; Oshogbo, Southern Nigeria, 

 x. 1910 (Dr. T. F. G. Mcfyer)-, Obuasi, Ashanti, W. Africa, 

 x. 1907, " caught on window " (Dr. W. M. Graham). 



Genus 14. LATHYROPHTHALMUS, Mi'k (1897). 



I have adopted here for practical purposes the present group, 

 which is evidently an artificial one, based only on the spotted eyes 

 of the male. It contains heterogeneous elements, such as species 

 with bare eyes or with widely separated eyes in the male sex ; but, 

 as a rule, the eyes are united and densely pilose on the upper half. 

 No doubt the naked-eyed species, with conical abdomen, form a 

 transition to Simoides, from which they are distinguished only by 

 the spotted eyes. 



The rather numerous species in the collection can be divided into 

 five distinct groups, viz. : (1) Eyes bare, separated in the male ; 

 face produced below. (2) Eyes bare, united in the male; face 

 produced. (3) Eyes hairy; face produced, with a broad black 

 stripe. (4) Eyes hairy ; face not produced, with three black- 

 stripes. (5) Eyes hairy; face kss produced, with a yellow tubercle; 

 body short and broad. 



1(10) Face very much produced below, almost 



conical ; antenual tubercle very 



prouiiiient ; third autennal joint 



entirely black, or only narrowly 



yellowish below ; black spots on the 



eyes coalescent, sometimes lused; 



eyes of the males touching for a 



short distance or separate. 

 '2 (7) Eyes quite bare ; third joint of the 



antenna} rounded, "wholly black ; 



autennal tubercle and face grey 



pollinose, the facial tubercle black ; 



hind femora rather thick ; hind tarsi 



black. 



3 (4) Eyes of the male widely separate as in 



Simoides ; fourth ventral segment of 

 the male with a long bilobed appen- 

 dage; hind femora yellow on the 

 basal half; fourth abdominal seg- 

 ment brown or black, with the 

 whitish hind baud alone ; thorax 

 not banded niodestus, Wied. 



4 (3) Eyes of the male united along a short 



line; fourth ventral segment with- 

 out appendage. 



5 (6) Hind femora broadly yellow at the 



base; thorax on the* back with a
