to between the bases of the antennae; first five joints of antennae 

 ferruginous (last five broken off), comparative lengths of antennal 

 joints as follows: 6, 4, 11, 11, 8, third to fifth joints much longer 

 than wide (11:1), indicating that the antennae are very long and 

 slender. Pronotum divided into a wider, shorter anterior part, and 

 a narrrower elongated elevated posterior division, very similar to 

 GhalcogonatopiLS, with a fine areolate sculpturing; thoracic con- 

 striction much longer than wide (7:2); with fine areolate surface 

 sculpture; chela as in Figure 7. Propodeum in profile and on sides 

 rounded, so that it is hemispherical in shape, separated laterally by 

 a distinct suture into the meso and metapleura and arising above 

 the thoracic constriction, sparsely pilose and finely areolate on sur- 

 face. Abdomen minutely areolate, blackish brown.

DEINODRYINUS VARIABILIS, new species 



FcTnale. — Length, 6.3 mm. General color black except as noted 

 below: Head black except face, clypeus, and mandibles, which are 

 testaceous, teeth of latter dark; vertex rugose with scattered fine 

 white hairs; antennae slender, testaceous except five terminal joints 

 which are fuscous to black, comparative length of joints as follows : 

 7, 5, 14, 10, 7, 7, 5, 5, 5, 6. Prothorax slightly wider than long, 

 notched at union wdth mesoscutum, narrower than latter, surface 

 with dense coarse punctation and with white pilosity, latter being 

 thicker on sides than on dorsum ; pronotum black with narrow testa- 

 ceous band on posterior margin next to mesoscutum; latter smooth, 

 polished, with scattered fine white pubescence, black except ferru- 

 ginous areas along parapsidal furrows, these deep, somewhat con- 

 verging, and extending almost the length of the mesoscutum; 

 scutellum black, polished, smooth, posterior margin arcuate; post- 

 scutellum black, smooth; legs ferruginous except small infuscated 

 area on hind coxae; chela with median arm long, extending to tip 

 of second tarsal joint, lamellate on tip and with a double row of 

 lamellae extending almost to articular cavity, claw, curved, unarmed, 

 without subapical tooth. Propodeum rugose with fine white hairs. 

 Abdomen smooth, polished, black, appearing dark fuscous in some 

 lights. 



The paratypes are similar in size and structure, but coloring is 

 very different and is as follows: General color ferruginous, a larger 

 area on vertex being black and face and antennae testaceous to 

 ferruginous. In one specimen there is a black area on sides of the 

 collar of the pronotum, and the carinae are indistinct, while in the 

 other, three distinct carinae are present extending from the ocelli to 

 the base of the clypeus and also bordering the eyes.
