ON ANEW SPECIES OF MYMAEIDAE FROM TRINIDAD. 

 By Chakles O. Waterhouse, I.S.O. 



Anagrus flaveolus, Waterhouse, sp. n. (fig. 1). 



Clear pale lemon yellow. The antenna with the 4th to 9th joints very pale 

 grey. Third joint very small, a little longer than broad, about half the length of 

 the second joint. Fourth joint rather slender, the length of the 2nd and 3rd 

 taken together. The fifth about one-quarter shorter, about the same width. 

 The 6th, 7th and 8th subequal, about the same length as the 5th but rather 

 broader. Wings hyaline, with a very slight shadow below the vein, very nearly 

 nine times as long as the greatest width ('525 x '06 mm., approximately). 

 Marginal cilia moderately strong, the longest *132 mm. There is a line of hairs 

 running along the middle of the wing from the apex of the vein to near the

apex of the wing ; between this and the front margin there is another line of 

 about twelve hairs, rather irregular, and there are a few hairs irregularly placed 

 in the apical area. Between the central line and the hind margin there is an 

 irregular line of about eight hairs, but they are not the same on both wings. 

 Hind wings free from surface hairs, except three or four at the extreme apex. 

 The posterior cilia moderately stout, except the first three or four, the longest 

 about '1 mm. 



The specimens were in spirit, but appear to have retained their natural colour. 

 The figure is from one of the specimens mounted in balsam by myself and 

 micro-photographed by Mr. Enock. 



The insects were forwarded to the Imperial Bureau of Entomology by 

 Mr. P. Lechmere Guppy, Assistant Entomologist to the Board of Agriculture, 

 Trinidad, who bred them from eggs of the corn leaf-hopper, Peregrinus 

 \Delphax) maidis. 



[Dr. R. C. L. Perkins, who has examined this insect, informs us that it is 

 extremely closely allied to Anagrvs frequens, Perkins, originally described from 



Bull. Ent. Res. iv, pt. 1, May 1913.
