COGIA.— TYPHEDANUS. 341 



In some respects this species resembles Bhabdoides epigona, especially on the upper 

 surface ; but it may at once be distinguished from that species by the presence of a 

 small tuft of hairs on the secondaries attached to the interspace between the median 

 and submedian nervures near the base ; this doubtless is a male character, but of suffi- 

 cient importance to indicate the genus into which the species should be placed. 



We have a number of specimens sent us by the late T. K. Morrison from Fort Grant, 

 Arizona, and these agree fairly with Mr. Edwards's description of Eudamus hippalus — 

 no mention, however, being made of the tuft of hairs on the secondaries. The Arizona 

 examples differ in no way from a series from the Mexican States of Vera Cruz and Guer- 

 rero in our own collection and in that of Mr. Schaus. A Guerrero specimen is figured. 



The male genitalia have a tegumen ending in a single depressed point ; the scaphium 

 is fairly developed : the harpes are truncate, ending in a concave depression with a 

 rounded lobe at each corner ; the distal half of the dorsal edge is concave, with a few 

 strong teeth on the proximal portion, followed by a serrate edge to the end. The 

 cedeagus is filled with strong spines. (See Tab. LXXX. fig. 31.) 



TYPHEDANUS. 



Typhedanus, Butler, Trans. Ent. Soc. 1870, p. 497; Wats. P. Z. S. 1893 ; p. 34. 



Mr. Butler described this genus in 1870 from a supposed new species, T. zephus 

 in Mr. Druce's collection, but which now proves to be Telemiades umber of Herrich- 

 Schaffer *. 



The characteristic features of Typhedanus are its elongated pointed secondaries and 

 the brush of erectile ochraceous hairs which lie in the abdominal fold and start from the 

 angle between the median and submedian nervures. This brush is similar to that 

 possessed by typical species of Cogia, but the pointed secondaries serve to distinguish 

 Typhedanus from that genus. 



The antennae have a moderate club bent into a hook, the attenuated end slender and 

 not more than half as long as the rest of the club. The third joint of the palpi is small, 

 hardly showing beyond the scales of the second joint. Primaries pointed, the cell 

 more than two-thirds the length of the costa ; the third subcostal segment longer than 

 the second and fourth together ; the middle and lower discocellulars subequal and in a 

 straight line ; the third median segment about half the second. Secondaries produced ; 

 the third median segment about half the second segment, the second median branch 

 starting some way from the end of the cell. Primaries without a costal fold ; second- 

 aries with a large erectile brush of hairs arising between the median and submedian 

 nervures, and when withdrawn lying in the abdominal fold.
