following, all longer than broad. Head short, broadly transverse, slightly 

 broader than thorax ; lateral ocelli separated from the eyes by a space 

 about equal to their own diameter ; a depression in front of middle ocel- 

 lus. Frons and face minutely reticulated by grooves, reminding one of 

 crocodile hide. Thorax subglobular, somewhat broader than long, with 

 very sparse short pubescence ; anterior part of mesothorax very indis- 

 tinctly subreticulately sculptured, its anterior margin with a distinct row 

 of pits. Hind portion distinctly but very delicately and minutely reticu- 

 lated with raised lines. Scutellum smooth, with a few hairs ; hind margins 

 of scutellum and postscutellum with a row of pits. Abdomen short and 

 broad, carinated at sides, smooth, rather shiny. Wings hyaline, quite 

 hairy, fringe short, nervures rufofulvous ; marginal vein short, not half 

 length of stigmal. 



Habitat. — Las Cruces, New Mexico ; bred from eggs of some 

 Hemipteron, apparently Pentatomid. The eggs are barrel-shaped, pale gray 

 with a white base and a white ring at top, the lid with a white central 

 ringlet, and its suture white. Only one specimen was bred, and the tips 

 of its antenucTe are broken off, but the species differs at once, by its reticu- 

 late sculpture and other characters, from all those described by Mr. 

 Ashmead in his Monog. Proctotrypidae or in his work on the Hymenop- 

 tera of St. Vincent. Another parasite of Pentatomid eggs occurs in the 

 Mesilla Valley, namely, Trisso/cus etischisti, Ashm. (a Mesilla example det. 

 Ashm.). With us, I believe it is a parasite on the eggs of Brochyinetia 

 obscura, H. S. , whicli abounds in orchards. 



NOTES OM VANESSA INTERROGATIONIS. 



BY W. F. FISKE, MAST YARD, N. H. 



I remember about ten years ago to have taken several large speci- 

 mens of a Grapta, probably G. interrogationis, but they were lost without 

 being identified. I saw no more of the species until August, 1895, when 

 I took a fine example of the form Fabricii. It proved to be the forerunner 

 of a "wave" of the species, and from that date until frost a number were 

 seen, perhaps in all twenty or more, but all but two of them were of the 

 form Fabricii. This spring I watched the hibernating butterflies closely, 

 hoping to obtain a fertile female and rear a brood of larvte, but although 

 there were many G. comma and J-album, and a few progice and f annus, 

 on the wing throughout April, I did not observe one inten-ogationis 

 amongst them. By the middle of May the other species of Grapta had
