314 THE CANADIAN KNTOMULOOISt. 



tliorax, almost flattened above, not deeply keeled ventrally, widest near 

 apex, and with a dorsal fulvous area near base expanding to the lateral 

 edges ; otherwise agreeing wiili females. 



Type : Piano, Texas, July 26, 1909 ; emerged August 6. 



Paratypes show some variations of colour ; the greenish tinge of 

 head and thorax being stronger in some examples than others, and the 

 tlagellum is sometimes nearly or wholly black. 



Length of female type and paratypes ranges from 1.25 to 2 mm.; 

 male type and paratypes from i mm. to 1.5 mm. 



A single specimen reared with Vandinei from same material collected 

 by Mr. D. I,. Van Dine at Welsh, La, August 2, 1909, represented another 

 species, which is described as follows : 

 Meraporus requisitus, n. sp. 



Male: Length, 1.25 mm.; resembling Vandinei and similarly punc- 

 tured, but distinguished by blacker colour of body, and paler legs, 

 including fore cox;e, the femora only dull brown ; no mctathoracic carina, 

 nor fulvous area on base of abdomen ; first and second funicle-joints little 

 longer than wide, third to fifth subquadrate ; left mandible with three 

 denticles, but four on the right. 



The genus Meraporus, as established l»y Francis Walker (Mono- 

 graphia Chalciditum, P^nt. Mag, v. 2, 1834, p. 298), was accorded 12 

 antennal joints, but in Ashmead's classification, it is considered as having 

 13 joints of the antenna;. \Valker very likely failed to distinguish more 

 than two ring-joints. In fact, the entire three ring-joints, particularly of 

 male examples, are difiicult objects for clear definition even under a 

 binocular with high |)()wcr magnification. 



Three previously described species of Meraporus have been recog- 

 nized in the United States : calandra How., has an asymmetrical 

 denticulation, the right mandible with four denticles, and the left with three; 

 bruchivorus Ashm., is readily known by the smooth lower face and cheeks, 

 besides larger size ; and dubius Ashm., although characterized by a 

 tricarinate nietanotum, is said to have strongly curved lateral folds, and 

 subcosta neatly three times as long as the marginal vein. 



The very helpful assistance of Mr. ]. C. Crawford in the study of my 

 specimens is gratefully acknowledged.
