OF WASHINGTON, VOLUME XIII, 1911. 79 



Commissioner in San Francisco, and witnessed the inspection 

 of a large steamer from Japan. 



Stanford University was visited, as well as Pomona College, 

 at Claremont, California. Photographs were shown of Prof. 

 V. L. Kellogg, Prof. A. J. Cook, and Prof. C. F. Baker. 



A visit was made to the Southern California Phytopatho- 

 logical Laboratory of the University of California at Whit- 

 tier. A photograph was shown of the laboratory and also of 

 the great Leffingwell lemon orchard, where they were in- 

 formed that the work of R. S. Woglum on the fumigation of 

 citrus trees with hydrocyanic-acid gas had already saved the 

 locality at least $250,000. 



Visits following these to Dallas, Texas; College Station, 

 Texas; Audubon Park, Louisiana; Baton Rouge, Louisiana; 

 and Urbana, Illinois, were briefly mentioned, entomologists and 

 entomological laboratories being illustrated by photographs. 



A NEW CACTUS-FREQUENTING ORTHOPTERON FROM TEXAS. 



BY A. N. CAUDELL. 



In their investigation of the insects of the cactus Messrs. 

 Mitchell, Hunter, and Pratt have taken a number of interest- 

 ing representatives of the subfamily Decticinae. I have re- 

 cently described one very distinct new species of the genus 

 Stipator? and I now present the description of another new 

 species of this, the dominant, genus of Decticinse. I take 

 pleasure in naming the species pratti in honor of Mr. F. C. 

 Pratt. 



Stipator pratti, new species. 



Male. Allied to mitchelli in general appearance but differs from 

 that species, as well as from haldemanii, its next nearest ally, in the 

 shape of the cerci and that of the last abdominal segment, in which 

 particulars it is more nearly allied to the much smaller S. stevensoni, 

 as figured in my revision of the group. 2 Head moderate, well inserted 

 into the ponotum; fastigium of the vertex slightly more than one- 

 third as broad as the interocular space; front very broadly rounded; 

 eyes moderate, a little longer than broad, somewhat larger than in 

 mitchelli; antennas as usual in the genus. Pronotum large and pro- 

 duced posteriorly considerably over the base of the abdomen; lateral 

 lobes well developed but scarcely so deep as long, the posterior mar- 

 gin distinctly sinuate; lateral and median carina? wholly absent; an- 

 terior margin of pronotum truncate, posterior margin rounded; pro- 

 sternal spines moderate, sharp. Organs of flight not projecting from
