third yellow to cream. Pronotum and scutellum shiny; apex of scutellum 

 white or cream colored. Elytra dark brown, becoming even darker at 

 apex and along costal border. Two transverse white streaks at the base 

 , of the cuneus. Membrane smoky. Under side dark reddish brown, legs 

 dark with light bands at apex of femur and tibia. Middle and hind coxae 

 white. 



Described from seven females and three males collected by 

 Messers E. A. Schwarz and H. S. Barber at San Diego and 

 Brownsville, Texas, and now in the collection of the U. S. 

 National Museum. 



Named in honor of the memory of the late Mr. Otto 

 Heidemann. 



This species can easily be recognized from all others of the 

 family by its extremely convex pronotum and color pattern of 

 the elytra. 



Genus Myiomma Put. — Myiomma Puton, Hemipteres, Ann. Soc. Ent. 

 France, Vol. 3, ser. 5, pp. 20^21, 1873. Heidemannia Uhler, Proc. Ent. Soc. 

 Washington, Vol. 2, No. i, 1891. 



Form elliptical, nearly flat above. Head small, projecting above the pro- 

 notum ; eyes large ; vertex triangular ; face oblong, curving backwards be- 

 neath. Antennae attached beneath inner angle of the eyes. Pronotum 

 transverse, anterior border much narrower than posterior; lateral margins 

 flaring. Costal margins of elytra feebly curved, broadly reflexed; mem- 

 brane blunt. Legs short, anterior femor wide. Type of the genus is 

 fieberi Put. 



Myiomma cixiiformis Uhl. — Heidemannia cixiiformis Uhler, Proc. Ent. 

 Soc. Washington, Vol. 2, No. i, 1891. 



This species can be easily separated from all other Isometopidse by the 

 extremely small head with eyes nearly meeting. Both Uhler and Heide- 

 mann dwelt on the habits and description of this species in detail in their 

 treatises. It is knoAvn to occur in New York, Delaware, Maryland, and 

 Virginia. 



Myiomma media n. sp. — Head short, broad, vertical, with apex depressed 

 as in cixiiformis Uhl. Eyes large and bulging as in Isometopus. Dis- 

 tance between eyes slightly less than width of an eye. Ocelli large, promi- 

 nent and considerably raised. Posterior border of head distinctly concave. 

 Pronotum short and broad, much narrowed anteriorly. Lateral sides of 

 pronotum if produced would meet at a point on the front of the head. 

 Lateral margins flaring but not as much so as in Isometopus. Scutellum 

 large, longer than the basal width. Pronotum and scutellum strongly pu- 

 bescent. Elytra elongate, sides nearly straight. Length 2.5 mm. 



Color. — Head, pronotum, and scutellum dark reddish brown. Elytra 

 light fuscous, blotched with darker fuscous. Reddish beneath.
