 tliird as long as tliinl. Tribe 1. Ask.mim, li. 1014.

 iiHire than one-tbii'd as long as third.

Trilic I. .\SI':MIXI. 



In this trilu^ the antenna' ai-e densely ])iinetur-eil and pvibeseent. 

 with the second joint nearly half the length of third and the 11th 

 simple; front eoxie transverse, with distinct troehantin, the cavities 

 open behind; scutellum rounded behind; males with fifth ventral 

 segment transverse and sixth segment visible; females with fifth 

 segment prolonged, sixth invisible. In this and many of the fol- 

 lowinii' tribes the character of the granulation of the eyes is much 

 used in separating the genera. In tliose which ai'e "eoarsel.v gran- 

 ulate" the lines between the facets are deeply inipi-essed. In the 

 second group the gi-;inulati(ins ar(j much finer, the lines feebly im- 

 pressed, the surface of the eye appearing almost plane. Repre- 

 sentatives of three oi' the seven genera comprising the tribe have 

 been taken in the State, while those of another probably occur. 



KEY TO INDIANA QENIOHA OF ASEMINI. 



a. Color blacli or dark brown; form eyliiidrioal, scarcely depressed; epi- 

 niera of mesothorax truneafe at inner end. 

 &. Eyes not wholly divided, often deeply emarginate. 



c. Eyes moderate in size, transverse, finely granulated and hairy; aii- 

 tennjs flnely pubescent. Asemum. 



ec. Byes large, coarsely granulated, not haii-.v. IV. ('riockphalus. 



hi). Eyes divided, .npiiarently four in number, rather linely granidated. 



A'. Teteophm. 



iia. Color pale yellowish; form depressed; epimera of uiosothorax narrowed 



and acutely pointed at inner end. \'I. smodicum. 



A.'iriinnii iiuvsluvi Ilald., black, oi)a(|ue, thorax rounded at si.les, 

 length 12-ir) mm., ran-es hum "Lake Superior to VU^vuXa and 

 eastward." 



IV. (UiiocKPHALTis ]\luls. ISDI). ((Jr., "a ram -I head.") 



This genus comi)rises seven rather laruv, subeylindrh^al species, 

 having the eyes coai's.dy granulated, not hairy and the thorax with 

 two to four large and shallow depressions on the disk-. One of the 

 seven has been taken in Indiana and another may occur.
