intestines of those dissected. The first pair taken in coitu was found 

 August 16, though in Indiana many pairs were found by Blatchley by 

 the first of August. 



20. KOBUSTUS SERIES. 



In this group the male prozona is quadrate or a little longitudinal 

 and the interspace between the raesosternal lobes of the same sex 

 twice or more than twice as long as broad. The eyes are rather widely 

 separated and the frontal costa broad and equal. The prosternal spine 

 is usually long. The tegmina are fully developed or only a little 

 abbreviated and either feebly spotted, longitudinally streaked or wholly 

 free from markings; the hind tibiae are yellow or red, with from ten to 

 twelve spines in the outer series. 



The supraanal plate is shield-shaped or triangular with feebly con- 

 vex or sinuous sides, and with the surface tolerably flat; the furculais 

 entirely wanting or in one or two instances barely indicated; the cerci 

 are excessively broad and stout, apically greatly expanded and flabel- 

 late, with the apical border either convex or more or less emarginate; 

 the subgenital plate is longer than broad, generally moderately narrow, 

 a little elevated apically and sometimes considerably prolonged, always 

 entire. 



It comprises insects of the largest size only and of a stout and bulky 

 aspect. Five species are known, occurring in the southern half or 

 more of the United States.
