ARADIDAE — KORMILEV 217 



and infraocular carinae) slightly longitudinally depressed. Vertex 

 with V-shaped row of tubercles. Antennae slender; with proportions 

 of the antenna! segments (1 to 4) 6:6:7:13. Rostrum reaching the 

 hind border of the rostral groove. 



Pronotum much shorter than wide (27:67). Fore disc with four 

 (2+2) tubercles forming two, slightly divergent backward rows, 

 which are continued on the hind lobe (outer rows). Hind lobe with 

 four rows of tubercles; the outer rows consist of three tubercles each, 

 the inner ones of four smaller tubercles; all foiu- rows are strongly 

 divergent posteriorly. 



Scutellum very long (103:57); the basal triangular elevation pro- 

 vided with six (3-f-3) bigger and a few smaller tubercles; median 

 carina finely granulated; margins of the scutellum each with a row 

 of small, erect teeth, running to two-thirds of their length, then 

 without teeth. Disc roughly pimctured, and with a few dispersed, 

 erect tubercles. 



Abdomen (figs. 11, 12) very long (100:81); each connexivum with 

 two brown tubercles and 1 yellow tubercle (upper row). Tergum 

 VII longitudinally inflated in the middle; sternum vii with two (1 + 1) 

 big, rounded lobes, protruding far beyond the tip of the hypopygium; 

 genital lobes (of sternum viii) shorter than the hypopygium and not 

 visible from above. Hypopygium small, posteriorly granidated. 

 Spiracles of segments ii-vi ventral, those of vii lateral and visible 

 from above. Venter finely granulated. 



Color: Ochre-yellow, mottled with brown; scutellum whitish; basal 

 triangle, the tip (narrowly), and some irregular spots on the disc 

 brown; lateral borders in the middle piceous; ventral surface of the 

 body with carmine punctures and spots. 



Female: Sexual dimorphism is rather pronounced, the female 

 having a much shorter and more ovate abdomen, without big rounded 

 lobes on sternum vii, and with only segment ix protuding posteriorly. 

 Proportions: head 38:40; pronotum 32:70; scutellum 100:55; ab- 

 domen 100:86; antennal segments (1 to 4) 6:7)^:7)^:13. 



Size: Total length of male and of female, 3.47 mm. Width of 

 pronotum: male, 1.12 mm.; female, 1.17 mm. Width of abdomen: 

 male, 1.35 mm.; female, 1.43 mm. 



Holotype: Male (USNM 64207), Paraiso, Canal Zone, Panama, 

 Jan. 23, 1911, E. A. Schwarz. 



Allotype: Female, same data as holotype. 



Paratypes: 14 paratypes, same data as holotype, deposited in the 

 U. S. National Museum and in the collection of the author. 



Remarks: Calisius longiventris, new species, is allied to affinis 

 Barber, 1954, but is lighter in color; the body of tbe male, particularly 

 the abdomen, is much longer and posteriorly more narrowed; and the
