362 THE CA.NA.DIAN ENTOMOLOGIST. 



Ac7itia neomexicann, Siniih, notwithstanding the name, was not de- 

 scribed from New Mexico. Fortunate!}' the name is justified by a 

 specimen in tlie National Museum, collected by myself at Las Cruces, 

 N. M,, in April. 



Cinophamis Dyari, Ckll. — Described from New Afexico, is also 

 found in the Huachuca Mts., Arizona. (In coll. U. S. National Museum.) 



Two Parasitic Hymenoptera. 



I have recently described two parasitic species, basing my conclusions 

 as to their distinctness on published descriptions. I gave the types to 

 the National Museum, and when recently in Washington took occasion to 

 compare them with their nearest allies. 



Proctotrypes Coloradicus, Ckll., is darker and rather more robust than 

 P. pallidus, Say. Dr. Ashmead thinks it is a form of paliidus, and this 

 is very likely the case. I will take the opportunity to record that P. 

 rufigaster, Prov. (det. Ashm.), was collected by myself at Monument 

 Rock, Santa Fe' Canon, New Mexico. This is the first record of the 

 genus from New Mexico. 



Porizon Vierecki, Ckll., differs from the allied hyalinipennis, Cress., 

 (type compared) by the white veins of the wings, and especially by the 

 much more slender hind femora. P. hyalinipennis has thick femora in 

 both sexes. 



A NEW DEXIID PARASITE OF A CUBAN BEETLE. 



13Y D. W. COQUILLETT, WASHINGTON, D. C. 



Thelairodes ischyri, new species. 



Black, the antenn?e, palpi, labella and front corners of the first two 

 abdominal segments pale yellow, the last segment and hind edge of the 

 preceding orange yellow. Front at narrowest part one-fifth as wide as 

 either eye, the upper three pairs of frontal bristles much larger than the 

 others, one pair beneath insertion of antennae, facial ridges strongly diverg- 

 ing below, antennae slender, almost as long as the face, the third joint five 

 times as long as the second. Mesonotum gvav pruinose. a broad fascia 

 behind the suture, and four vittaj in front of it black, three postsutural and 

 two sternopleural bristles. Abdomen bearing marginal bristles on the last 

 three segments, and with a discal row on the last one ; abdomen polished, 

 the last three segments narrowly whitish pruinose on their bases. Pulvilli 

 much shorter than the last tarsal joint. Wings hyaline. Length, 6 mm.

 April, at Santiago de las Vegas, Cuba, by Dr. George Dimmock, Type 

 No. 8458, U. S. National Museum.
