Galveston, Texas, August 22, 1918. male (E. C. Wurzlow). 

 Davis collection. Mr. Wurzlow wrote that he heard this insect 

 singing, and found it on a fence over a clump of Ainaranthus. He 

 also heard several others in the gardens about the houses. 



Tibicen texana (Davis). 



In the original description in this Journal for 1916, this species 

 was recorded from three localities in Cameron County, southern 

 Texas. The following Texas specimens have since been examined: 

 Spofford, Kinney Co., July 8, 1907, male; CotuUa, Lasalle Co., 450 

 ft., August 13-14, 1912, male; Uvalde, Uvalde Co., 1.000-1,100 ft., 

 Aug. 21-22, 1912. male; Del Rio, Valverde Co., 900-1,100 ft., Aug. 

 22-23, 1912, male and female in copulation; Midland, Midland Co.. 

 2,779 ft., Sept. 19, 1912, male. These six specimens are in the 

 Academy of Natural Sciences of Philadelphia and were collected by 

 Rehn and Hebard. 



The female of this species has never been described, so it may 

 be well to state that the notch in the last ventral segment is broadly 

 V-shaped with the sides of the V slightly sinuate, as in olympusa 

 (sordidata), but judging from the only female of texana examined 

 the V incision has the sides more evenly curved and broadly rounded 

 out than in olyiiipiisa. In addition the head is broader than in that 

 species. 

 Tibicen vitripennis var. bequaerti Davis. 



This insect was described and figured in the Journal of the 

 New York Entomological Society for December, 1917, under the 

 name of Tibicen viridifascia var. bequaerti. The type and four 

 paratypes were recorded from Richmond, Texas, June 23, 1917. and 

 four paratyj)es from Wharton, Texas, June 24, 1917, all collected 

 by Dr. H. H. Knight. It was stated at the time that the eyes were 

 prominent in these specimens ; also that the basal cell of the fore 

 wing was clear, slightly touched with black along the fore margin. 

 More material has been examined, and the writer now thinks that 

 this insect should be considered as a variety of vitripennis Say. in- 

 stead of viridifascia Walker, particularly on account of the more 

 elongate shape of the fore wings, and the clearer basal cell. In the 

 writer's collection there are at present thirty examples of z'itri- 

 pennis, and when these are compared with examples of variety
