THYNNIDAE IN THE UNITED STATES. 



BY WILLIAM H. ASHMEAD, WASHIxNGTON, D. C. 



In Ent. News, Vol. Ill, p. 104 (1S92), the 

 following brief notice by Mr. Wni. H. Patton 

 occurs: "Thynnus in C.ilifornia. This 

 genus has not hitherto been found north of 

 the equator in either hemisphere, nor has 

 any of the family Thynnidae. A single 

 specimen received from Dr. F. E. Blaisdell, 

 from Poway, San Diego County, Cal., is the 

 lirst intiination of its occurrence in North 

 America. It is a small black species -with 

 hyaline wings and may be named Thynnus 

 californicus." 



The author has not since published a 

 description of this interesting insect and the 

 above laconic description is too insufficient 

 for me to tell whether or not it is at all 

 related to the two Th^'nnids, described below, 

 also from California. 



Telephorotnyia afithracina n. sp. — $. 

 Length 13-14 mm. Black, shining but 

 punctate, and clothed with black hairs, the 

 hairs greyish on scape, the clypeus anteriorly 

 and the anterior femora beneath. Clypeus, 

 a small triangular spot above between the 

 antennae, and the inner orbits to above the 

 middle of eyes yellow or yellowish white. 

 Wings violaceous black, paler or hyaline at 

 basal one-third. Mandibles tridentate, the 

 outer tooth the longest, acute. Mesonotum 

 with four more or less distinct longitudinal 

 grooved lines. Claws with a tooth at the 

 middle. 



Hab. — Los Angeles, California. 



Type — No. 5053, U. S. N. M. 



Described from two specimens collected 

 by Mr. D. W. Coquillett. 



The genus Telephoromyia is peculiar to 

 South America. 



Glyptometop.v n. g. 



Body smooth, polished, unpunctate, 

 clothed with very sparse, long yellowish- 

 white hairs. Head viewed from above quad- 

 rate, a little wider than long, with a long 

 curved sulcus on each temple above the eye, 



the sulcus fringed witli long hairs. Ocelli 

 wanting. >Landibles bidentate. Eyes not 

 large, oval, placed at the anterior angles of 

 the head and almost touching the base of 

 the mandibles. Maxillary palpi 6-, labial 

 palpi 4-jointed. Antennae 12-jointed, short ; 

 the scape dilated, with a tuft of bristles 

 above, and as long as the pedicel and the 

 first two joints of flagellum united: the 

 flagellum is about as long as the head is 

 wide; pedicel shorter than the 'first flagellar 

 joint, the latter being shorter and slenderer 

 than the following joints; the last joint 

 the longest, as long as the pedicel and the 

 first joint of flagellum united. Thorax about 

 2h times as long as wide, divided into three 

 parts, the pronotum quadrate, the anterior 

 angles a little rounded, and as long as the 

 metathorax: mesonotum transverse, entire, 

 about half as long as the metathorax, the 

 scutellum not differentiated; metathorax 

 viewed from above trapezoidal, the posterior 

 face and sides perpendicularly truncate. 

 Legs fossorial, the middle and hind legs 

 armed with short spines on anterior face, 

 with longer spines at apex ; tibial spurs 1,2, 

 2 ; tarsi long, each pair gradually increasing 

 in length, the hind pair being the longest, 

 the joints armed with spines; claws simple. 

 Abdomen subsessile, long, subcylindrical,
