LARVAL TAXONOMY OF THE TKOGINAE IN NORTH AMERICA 51 



posterior border vertical. Each anterior angle of frons with about 5 to 

 8 setae. Epipharynx with about 1 8 to 24 setae near anterior border on 

 each side of corypha. Sclerotization of haptomeral region most pro- 

 nounced just anterior to sensory spots of pedium in form of prominent 

 transverse band. Sclerotized band on each side of pedium reduced in 

 anterior region, becoming more pronounced posteriorly. Usually with 

 a few small phobae posterior to each fused phobal mass. Paria with 

 about 18 to 30 anterior setae and about 6 to 10 stouter posterior setae 

 on each side. Sense cone of haptolachus with central hyaline region 

 often traversed by median longitudinal, darkened area. Glossa with 4 

 sensory spots and about 8 to 12 setae dorsally; with 2 sensory spots and 

 2 long setae ventrally. Hypopharynx with transverse band of caudally 

 directed phobae at base of smaller distal area; without phobal patch 

 at end of right subapotorma. Maxilla with stipes bearing 1 to 4 setae 

 on exterior surface. Maxillary stridulatory area with longitudinal row 

 of about 18 to 30 stridulatory teeth. 



Prothorax with about 45 to 60 setae on lateral lobe. Infraepisternal 

 area with about 2 setae; infraepimeral area with about 10 to 15 setae. 



Mesothorax with about 36 to 50 setae on lateral lobe. Infraepi- 

 sternal area usually devoid of setae ; infraepimeral area with about 20 

 to 25 setae. 



Metathorax with transverse row of about 8 to 10 spinules and 4 to 6 

 setae on smaller dorsal lobe (DL2). Anterior lateral lobe (LLl) with 

 about 12 to 15 setae. Posterior lateral lobe (LL2) with about 30 to 38 

 setae. Infraepisternal area with 1 to 2 setae; infraepimeral area with 

 about 20 to 24 setae. 



Legs with each tibiotarsus with terminal whorl of 6 setae plus about 

 14 to 18 setae proximad of whorl. 



Abdomen with transverse rov/ of about 22 to 26 setae and 5 to 7 

 spinules on DLl of segment 7.

 adults collected at cow and javelina carcasses, and single larvae 

 collected under a sheep carcass and a javelina carcass about 0.5 mile 

 east of Hebbronville, Jim Hogg Co., Tex., July 13-15, 1964, by David 

 R. Smith and Charles W. Baker.
