ART. 8 NEW HYMENOPTEKA, SUBFAMILY ANTEONINAE FENTOIT 7 



thickened distally, five to ten thicker than four, each somewhat 

 broader than the one preceding, apical joints somewhat more than 

 twice as long as wide; comparative antennal lengths as follows: 

 9, 3, 10, 5%, 51/2? 5, 5, 5, 5, 7. Prothorax minutely areolated, with a 

 distinct transverse impression dividing it into two divisions, of which 

 the posterior is longer and narrower and is strongly elevated or 

 humped; thoracic constriction broad, about as wide as long, with 

 fine areolation, which is more distinct than on pronotum; legs; 

 fuscous with lighter testaceous markings; median arm of chela ex- 

 tending as far as third tarsal joint, lamellate at tip, with a row of 

 very small, short, widely spaced lamellae extending along the in- 

 crassate part nearly to articular cavity. Propodeum smooth, 

 polished on the disk posteriorly indistinctly areolate. Abdomen 

 smooth, polished.

CHALCOGONATOPUS AREOLATUS, new species 



Female. — ^Length 4.7 mm. General color ferruginous with darker 

 fuscous markings. Head ferruginous with central infuscated area 

 on vertex, wider than long (13:8) ; vertex broadly concave, surface 

 minutely and densely areolate; ocelli located near occiput, the 

 lateral ones being somewhat closer together than to median 

 one; mandibles, except amber-colored teeth, scape, second and 

 basal part of third antennal joints testaceous, rest of antennae 

 fuscous, comparative antennal lengths as follows : 5, 2, 12, 9, 5, 5, 5, 

 4, 4, 5. Prothorax divided by a deep impression into a transverse 

 anterior part and an elevated longer posterior lobe, surface sculpture 

 same as vertex of head; thoracic constriction about as wide as long 

 (7:6), with same type of surface sculpture as prothorax; legs long, 

 brownish-testaceous, fore trochanters with stalk shorter than club, 

 hind femora and tibiae unusually long; median arm of chela lamel- 

 late at tip and with a double row of lamellae extending from near 

 tip almost to articular cavity, these increasing slightly in length and 

 spacing toward the latter; claw slightly curved, without subapical 

 tooth and provided with a row of very small widely spaced teeth. 

 Propodeum surface with same type of sculpture laterally as pro- 

 thorax but anterior portion and posterior half with transverse 

 striations extending only part way down the sides. Abdomen fuscous 

 to ferruginous. 



Paratype similar in structure but different in color, being a clear 

 ferruginous without the darker fuscous markings of the type. 



Type locality. — Falls Church, Va.
