large, with praescutum small, necklike, depressed, and almost con- 

 cealed by mesothorax and scutum. Scutum narrowly connected in 

 front of the broadly rounded scutellum. There is no indication of a 

 fission to form the parascutellum. Postlumbium large, postscutellum 

 relatively smaller than usual. Wings with two anal veins lacking. 

 There are two small detached veins between redius and medius, but 

 none behind medius. Tarsi five- jointed, armed with tv>^o long claws.

TETROZOCERA SANTCHII, new species. 



Plate 66, figs. 1-4. 



Described from a single male collected by F. Santchi at Kairouan, 

 Algeria, in August. 1907. 



This species differs from Mengenilla chohautii Hofeneder. also of 

 Algeria in the following characteristics: The praescutum is de- 

 pressed, not raised to the disk. The scuti are connected, not sep- 

 arated by the scutellum. The scutellum is broadly rounded, not 

 acute at apex. The head is broadly emarginate, not sharply. The 

 eyes are diagonal, elongate, not rounded Avhen seen from above. 



The specimen had been rather badlj^ treated, having been origi- 

 nally in alcohol and later dry mounted. One wing is missing. It 

 has been impossible to locate the tiny scutellar triangle on the 

 epimeron, but it may be present. This is the first specimen in the 

 order in which the abdominal spiracles have all been visible. They 

 are quite large on all but the eighth segment. The first is located 

 just below the suture, between the lower lateropleurite and the 

 epimeron, but entirely on the first segment. The lateropleurite ex- 

 tends forward almost to the wing.
