and war, more wary than D. spinosus, and most numerous about the water from 

 9 a. m. to 4 p. m., where they are coa>picaous by reason of the yellow or reddish- 

 yellow seventh to ninth abdominal segments. 



3. Gomphus villnsipes Selys. Tippecanoe River, near Warsaw, June 23, 1901, 

 3 males. Holliday and Williamson. 



4. Gomphus dilataius Rambur. Tippecanoe River, near War.-aw, Jiui<» 23, 

 1901, 5 males, 1 female. Williamson and Holliday. This species was found 

 only near the P., Ft. W. & C. R. R. bridge over Tippecanoe River, and only on 

 this one date. The bridge was being repaired, and the dragonflies were taken 

 resting on some of the timbers, usually near the water, which flowed swiftly here. 

 Possibly half the number seen were captured. They did not patrol the river, 

 apparently, and, when frightened, they usually left the' river, disappearing over 

 the fields on either side. 



5. Gomphus spiniceps Walsh. Old canal feeder along the St. Joseph Kiver, 

 near Ft. Wayne, July 19, 1901, one teneral female taken, another teneral seen, 

 and two exuviae found in grass clumps two or three feet from the water. 



6. Si/mpetntm corrup'um Hagen. Near Winona Lake, August 10, 1901, 

 1 male. Miss N. O. Harrah. 



Ninety-seven species of dragonflies are now recorded for Indiana. If semiaquea 

 (or the form usually known by this name) and assimilatum should be regarded as 

 distinct from Tetragoneuria cynosura and Sympetrum rubicundulum respectively, 

 then the Indiana list numbers 99 species. 



NOTES AND CORRECTIONS. 



1. Arf/ia translata Hagen. PI. I, Fig. 1. Ab., male 30, female 28; h. w., 

 male 22, female 23. A dark colored species; post-ocular spots small, not con- 

 nected ; thorax nearly to first lateral suture black, narrow antehumeral and post- 

 humeral pale stripes, the latter only above; these stripes wider and the post- 

 humeral longer in the female; sides of thorax pale, second latiral suture with 

 a black stripe. Abdomen black ; pale, narrow, interrupted basal rings on 3-7 ; 

 male with a blue basal spot on 8 and 9, spot apically three-pointed, one point on 

 either side (half the length of the segment on 8, nearly the cntiie length on 9), 

 and the middle one on the dorsum; female with a pale lateral stripe the length 

 of the abiomjn, interrupted at bases and apices of segments, and placed lower 

 on 6 and 7. The distribution of this species, as now known, is such as to make 

 its discovery in Indiana possible.
