236 REPORT OF STATE GEOLOGIST. 



This curious long lieaded locust occurs in suitable localities 

 throughout Indiana, though Scudder in his catalogue gives its range 

 as the "southern United States." If lias been taken both in Steuben 

 and Lake counties, in the extreme northeastern and northwestern 

 corners of the State, as well as in nearly every other county where 

 collections have been made. Walker has recently taken a few speci- 

 mens near Point Pelee, Ontario. • It is found only in the tall grasses 

 and sedges along the margins of lakes, ponds, streams and swales, 

 and in such loealities is usually locally abundant. It reaches ma- 

 turity in central Indiana about July 20, and in the northern part 

 of the State a fortnight later. The hind legs are very slender as 

 the insect seldom leaps when disturbed, but uses the wings in strong, 

 zig-zag, noiseless flight, usually alighting on a stem of grass or sedge 

 a dozen rods away. Frank Hay, living on the north shore of Bass 

 Lake, Starke County, reports a flight of this species after dark on 

 the evening of August 13, 1901. Large numbers flew onto the porch 

 and against the house and many were captured and used for fish 

 bait. 



XVIII. Syrbula Stal (1873). 



Head nearly as long as the ])ronotuni, the occiput moderately 

 rounded and distinctly ascending. Vertex sub-triangular, the front 

 margin sub-acuminate, the sides rather prominent, the median carina 

 distinct. Lateral foveolae very small or wanting; when present, in- 

 visible from above. Antennae flattened at the base and acuminate 

 in both sexes; expanded apieally in the male. Pronotum with the 

 three caringe distinct; the lateral gently or strongly sinuate, so that 

 the disk is plainly -narrower in the middle; all the carinae cut by one 

 sulcus a little behind the middle. The lateral lobes of pronotum 

 about as high as long, their front and hind margins moderately ob- 

 lique, the latter a little sinuate; the lower margin more or less un- 

 dulate. Tegmina and wings well developed, exceeding the abdomen 

 in both sexes. Hind femora unusually long and slender, surpassing 

 the tips of the tegmina in our species. Hind tibiae armed on the 

 outer margin with 19 to 21 ralher small spines. Last ventral seg- 

 ment of male acutely conical. Three species are known from the 

 United States. Of these, one occurs in Indiana.
