INVESTIGATIONS ON THE MUTILLID WASPS 219 



pit on the second abdominal sternite, and in the propodeum being 

 shallowly reticulate; in canella the propodeum is ver}^ deeply and 

 coarsely reticulate. It is also similar to reclusa but differs from 

 that species in having the second abdominal segment entirely fer- 

 ruginous and the disk of the second tergite with separated punctures. 

 The first abdominal segment is always more or less reddish but in 

 most of the paratypes is considerably darker than the second. The 

 length varies from 6-9 mm. The genitalia are similar to montioola 

 and are therefore not figured. 



88. DASYMUTILLA RECLUSA, new species 



Plate 3, fig. 22 



Male. — Black, the second abdominal tergite yellowish-ferruginous 

 with the basal, lateral, and apical margins black ; clothed with sparse, 

 erect, black pubescence, except the apical tergites with sparse, incon- 

 spicuous, grayish pubescence; second sternite simple, without a me- 

 dian pit or other modification; length, 6.5 mm. 



Head entirely black, sparsely clothed with long, erect, black pubes- 

 cense; mandibles acute at the tips, bidentate subapically within; 

 anterior margin of clypeus weakly bidentate medially; clypeus 

 densely punctate; scape with a single distinct longitudinal carina, 

 and a second weak, indistinct carina, closely punctate, and clothed 

 with coarse, erect, black hairs; first segment of flagellum distinctly 

 shorter than the second measured dorsally, slightly shorter measured 

 ventrally; antennal scrobes not carinate above; front, vertex and 

 genae with moderate, close, more or less confluent punctures; pos- 

 terior margin of head somewhat excavated laterally ; relative widths 

 of head and thorax,, 4.5-4.75. 



Thorax entirely black, sparsely clothed with long, erect, black 

 pubescence; cephalic margin of pronotum punctate laterally, glab- 

 rous, impunctate and distinctly emarginate medially, not rounded 

 evenly into the dorsum ; dorsum of pronotum, mesonotum and scutel- 

 lum densely, somewhat confluently punctate; tegulae with scattered 

 setigerous punctures throughout ; cephalic margin of propleura very 

 feebly defined by a carina; propleura anteriorly with large, close 

 punctures, posteriorly with fine punctures; mesopleura with scat- 

 tered, large punctures interspersed with fine punctures anteriorly, 

 and with large, somewhat confluent punctures posteriorly ; metapleura 

 glabrous, impunctate, except for large punctures ventrally; sides of 

 propodeum shallowly, indistinctly sculptured anteriorly, becoming 

 confluently, foveately punctate posteriorly. 



Abdomen black, the second tergite, except the basal, lateral, and 

 apical margins, yellowish; clothed throughout with sparse, erect, 

 black pubescence, except the apical tergites with sparse, grayish
