EUTHRIPS AND HEDYCHRIDIUM IN NEW MEXICO. 



BY T. D. A. COCKERELL, EAST LAS VEGAS, N. MEX. 



THRIPIDyE. 



Euthrips trittci (Fitch.). — At Las Vegas, Hot Springs, N. M., on 

 May 17, 1903, I found Ribcs cereiiin, Dougl, presenting numerous flower- 

 galls of rather pumpkin-like form and greenish-white colour, about 9 mm. 

 long and 8 broad. These consisted of the swollen and deformed flowers, 

 the walls of the calyx being thickened and greatly inflated. I rathar 

 expected to find in them dipterous larvae, but they contained nothing but 

 thrips, which, I am sure, is responsible for the damage. After careful 

 comparison with the published accounts, and especially that of Mr. W. E. 

 Hinds, I am quite unable to separate the thrips from the well-known 

 Euthrips tritici. 



ChRYSIDID/E. 



Hedychridium amabile, sp. n. — Length about 3 millim., shining green 

 and crimson. Head yellowish-green, the vertex crimson, shading into 

 yellow ; antennae black ; thorax green, the pro- and mesothorax mostly 

 crimson dorsally, the crimson shading into golden at the sides ; scutellum 

 suffused with the same colours ; sides of post-scutellum, and hind corners 

 and narrow hind border of proihorax, more or less brilliant blue ; abdomen 

 yellowish-green shot with crimson. Ocelli in a not far from equilateral 

 triangle ; prothorax and mesothorax, seen from above, about equal in 

 length ; prothorax with large, close subconfluent punctures ; mesothorax 

 with well-separated punctures of various sizes ; triangular area at base of 

 metathorax with no median ridge, the area is minutely transversely ridged, 

 except at the lateral corners, where the ridges run obliquely ; sides of 

 metathorax irregularly cancellate ; abdomen very closely punctured, third 

 segment without any fovea or peculiarity of sculpture ; legs dark, basal 

 half of tarsi light reddish. AVhen the abdomen is viewed laterally, the 

 apex of the second segment is level with the base of the third. 



Plab. — Mesilla Park, N. M., on campus of Agricultural College, May 

 8, 1900. ( Cockerell ). A lovely little species, known from others by its 

 metathoracic sculpture. 



1 will take this opportunity to record Chrysis inflata, Aaron (det. 

 du Buysson), from the Wiegand Ranch, near Las Vegas, N. M., March r. 

 Wiih this the recorded New Mexico Chrysididse now number 19 species.
