"The genera mentioned are all widespread, and by no means confined to 

 the mid-alpine fauna. The study of the Chalcididse is, in fact, so little 

 advanced that we are in no position for generalizations like those 

 which you wish to make. I doubt, in fact, whether one-fiftieth of 

 our species in this family have as yet been described !" (in lift. Jan. 

 12, 1893.) 



To this Mr. Howard adds statistics regarding the genera supposed to be 

 only known from Colorado, and as the information embodied in these 

 is new and valuable. I give it under the several subfamilies, although 

 to use an Irish expression, it only proves that it doesn't prove any- 

 thing. 



EUCHARIN^. 



590. Stibula montana Ashm., West Cliflf. July 27, by sweeping herbage. As 



yet only known from Custer County, Colorado. There is a species of 

 Stibula in Virginia, but the genus is otherwise South American. Hym. 

 Colo. p. 24. 



EURYTOMIN^. 



591. Eurytoma bigelovise Ashm., West ClitT, bred from galls of Trypeta bige- 



lovise. Hym. Colo. p. 25. 



592. Eurytoma diastrophi Walsh, West CliflT, bred from galls of Ehodites ignota, 



Rkodites fiisiformans and R. bicolor. Also high-alpine. N. to Canada. 



593. Eurytoma studiosa Say, West CliflT, bred from galls of Cecidomyia n. sp . 



near hordeoides. Walsh. N. to Canada. 



594. Isosoma tiordei Harr., var. West CliflT, July 31 ; the variety with pale 



legs, % . N. to Canada. 



TORYMIN^. 



595. Monodontomerus montivagus Ashm. Also in California, parasitic on 



bees (see "Insect Life" 1892, p. 141). Hym. Colo. p. 25. 



596. Syntomaspis leucopus Ashm. MS., West CliflT. July 27, by sweeping 



herbage. 



597. Syntomaspis lazulella Ashm. 



598. " cupeipes Ashm., West CliflT, July 27, by sweeping herbage. 

 .599. " monticola Ashm. MS. ; see " Ent. News" 1890, p. 79. 



600. Torymus chrysochlora O. S., West CliflT, bred from Ehodites fusiformans 



gall. Also in the N. E. States. 



601. Torymus rudbeckise Ashm., West CliflT, bred from an undetermined gall, 



supposed to be Cynipid. Hym. Colo. p. 26. 



602. Torymus mag-niflcus O. S., West Cliff, bred from Ehodites bicolor galls. 



E. to Connecticut. 



603. Torymus cyaneogaster Ashm. MS., Ula, July 30. 



604. " sp., bred from galls on willow; see "Entom." 1890, p. 282. 



605. " n. sp., Ckll., bred from gall of Cecidomyia alticola. 



606. " sp.. West Cliff, May 19, by sweeping Thermopsis ; brilliant blue- 



green, with a long, straight ovipositor. 



TRIDYMIN^. 



607. Tridymus cobaltinus Ashm. MS., West Cliff, by sweeping herbage, July 27 



Mr. Howard writes, " we liave species of Tridymus from Richfield Springs, 

 N. Y., the elevation of which I should estimate at 1000 feet, and from 

 Washington, D. C, where, as you know, we are not over 200 feet above 

 sea-level."
