114 ENTOMOLOGICAL NWS. [Mar. ,'15 



two-thirds as long as that part of the abdomen behind the fourth 

 pair of legs. Just laterad to the hyaline plates is situated a pair of 

 bristles which extend backwards for about twice the length of the 

 plates. On the posterior corners of the abdomen is situated a pair of 

 very large bristles. These are over one-half as long as the body 

 of the mite. Just in front of this pair of large bristles is a smaller 

 pair about one-third as long. 



Legs moderate ; fourth pair reaching beyond the tip of abdomen 

 by the entire length of the tarsus. Length of body, 0.28 mm. ; width, 

 0.13 mm. 



Female. Body larger and more strongly chitinized than in male. 

 Cephalothorax as broad as long; sides almost parallel. Dorsal shield 

 of cephalothorax granular, two-thirds as broad as the cephalothorax 

 itself. Dorsal bristles situated near the incisions in the dorsal shield 

 for the second pair of legs. They are somewhat longer than the 

 cephalothorax. 



Abdomen about twice as long as cephalothorax. Dorsal shield of 

 abdomen rectangular, slightly over twice as long as broad. Posterior 

 tubercles of abdomen rather prominent, as long as the posterior seg- 

 ment from which they extend. The bristles borne by the posterior 

 tubercles are quite stout, each being about one-half as long as the 

 abdomen. Epiandrium crescent-shaped, strongly chitinized and almost 

 one-half as broad as the width of the body at the region where it is 

 situated. 



Legs similar to those of the male; fourth pair just reaching the 

 tip of abdomen, excluding the posterior tubercles. Length of body, ex- 

 cluding posterior tubercles, 0.40 mm.; width, 0.16 mm. 



From Ithaca, New York ; taken from meadow lark, Stnr- 

 nella magna Linn, by H. E. Ewing. 



Descriptions made from type specimens. Many males, fe- 

 males, and young collected. The crescent-shaped, or inverted 

 U-shaped, epiandrium, and the shortness of the anal suckers 

 characterize this species from most of the others. 



Lucilia morrilli T. A Correction (Dipt.). 



On page 112, volume XXV, of the NEWS, what is said under Lucilia 

 morrilli must be retracted. It was written when examination of the 

 type and cotypes was impossible. I have since examined these and find 

 that I was mistaken, and that the actual type and cotype material is 

 undoubtedly Ps. cornicina F. CHARLES H. T. TOWNSEND.
