SOME NEW LOCUSTID^E FROM INDIANA. 



BY W. S. BLATCHLEY, TERRE HAUTE, INDIANA. 



During the past four years the writer has been getting together a 

 collection cf Locustidce from various parts of the State of Indiana, with a 

 view of preparing a general descriptive paper of the species of that 

 family found in the State. In working over the material thus gathered 

 thirty-seven species are found to be represented, four of which are evi- 

 dently new to science. Of the four, three belong to the genus Orcheli- 

 mum and one to the genus Conocephalus. The former genus is repre- 

 sented in the collection by ten species and the latter by four. Below is 

 given a description of each of the four species believed to be new, together 

 with such notes concerning the distribution of each as I find in my field 



note-book. 



Conocephalus, Thunberg. 



Conocephalus pahistris, nov. sp. 



A small but comparatively heavy-bodied species, having the cone of 

 the vertex devoid of black markings and without a basal tooth j oviposi- 

 tor very short and broad ; posterior femora armed beneath on both 

 carinae. 



Cone of the vertex short and stout, the tip round, the deflexed front 

 with a dull median carina. Pronotum short, broad, the posterior margin 

 regularly rounded, the lateral carinae well defined, the entire surface 

 thickly and rather deeply punctate. Tegmina long and rather narrow, 

 regularly rounded to the apex ; of a more delicate texture than 

 in either C. ensiger, Harris, or C. robustus, Scudder. Fore and middle 

 femora with two short spines on the apical third of the lower outer 

 carina. Hind legs short, the tibiae but little more than half as long as 

 the closed tegmina ; the femora with plainly visible spines on both of the 

 inferior carinae, eight on the outer and six on the inner. Ovipositor a 

 little shorter than the hind.tibia±, broadest at a point about two-thirds the 

 distance from the base, thence tapering regularly to a sharp apex.
