placed by shorter and more densely arranged hairs. Length in type 

 2+ mm. 



Prescutellum relatively very large, several times larger than the 

 spiraculiferous plate, which, in turn, is larger than the postscutellum. 



The first and second spiracles vertically elliptical, others round or 

 nearly so ; anterior ones large, the first larger than the second, others 

 decreasing in size gradually from the second caudad, the posterior 

 ones very small. 



Ventral pores apparently present on only about twelve anterior 

 sterna; few in number and arranged in a narrow transverse band a 

 little caudad of the middle of plate, band tapering to ends, extending 

 across plate entirely on first plates, shorter on more caudal ones. 



Last ventral plate very wide, anterior and caudal margins straight; 

 lateral margins convex, converging caudad. Coxopleurae moderate, 

 apparently with a single large porigerous pit on each, covered by edge 

 of ventral plate excepting at ectal edge at which the plate is excised 

 to give free passage from pit. 



Anal pores obsolete, being closed or nearly so. 



Genital palpi in male short, conical, broad at base. 



Anal legs much longer than penult, strongly and uniformly crassate. 

 the fifth or ultimate article clawless, not reduced in diameter. 



Length 49 mm.; width 1.4 mm. 



Locality. — Austin, Texas. One male collected by Prof. T. H. 

 Montgomery. 



While this form has not been found strictly within our limits, it 

 may range into the southern portion, and is discussed here because of 

 its interesting relationship to Sogona.
