The lateral carin;e of the pronotum are .s]iai'[)er in this species than 

 in the next; the pronotum itself is proportionally a little longer, and 

 appears more so than it really is on account of the ])roadly rounded 

 posterior lohe. Tlie liind ft'inora, as well as the ovipositor, are a 

 little shorter than in dorsalis. and the apex of the ovipositor is more 

 bluntly rounded from above. 



Measurements: ]\lale — Length of body, 19 mm.; of pronotum, 9.5 

 mm.; of hind femora, 1(5. 5 mm. Female — Length of body, 21 mm.; 

 of pronotum, 9.5 mm.; of hind femora, 18 mm.; of ovipositor, 18 mm. 



Pachijnu'nis is, in Indiana. l)y far tlie more cdninion of the two 

 species. It has been taken in Lake, Marshall, Marion, Tutnam, Vigo 

 and Crawford counties, and doubtless occurs througliout the State, 

 frequenting the localities mentioned above under the generic de- 

 scri])tion. The earliest date on which a mature s])ecinien has ])een 

 noted w^as June Gth, in Vigo County. 



In a pleasing account of the notes and habits of the species, Mr. 

 W. T. Davis, he. cit., has written as follows: "Its song much re- 

 sembles that of Orcltclhnnm vuJgare, witli the ])ri'liminary r/y, zip. 

 omitted. It is a continuous z-c-e-e, with an occasional short il-. caused 

 by the insect getting its wing covers ready for action after a period 

 of silence. * * * Starting with raspberries, one kept in captivity 

 had the rest of the fruits in. their season, including watermelon, of 

 which he sliowed a marked a])preciation. If I offered him a raspljcrry 

 and then gradually drew it away, he would follow in the direction 

 of the departing fruit, and would finally eat it from my hand."
