2. Abdomen with hair all black beyond first segment. 



monticola Smith. 

 Abdomen with white apical hair-bands on segments 2 to 5. 



rhinoceros Mocs. 



3. Sides of face with pale hair; abdomen with metallic tints. 



remota Smith. 

 Hair of face all black 4. 



4. Smaller ; sides of thorax with light hair liiimilis Smith. 



Larger, 19-21 mm. ; thorax with fulvous hair above. 



sculpturalis Smith. 



M. monticola and rhinoceros have a process on the clypeus, 

 and are related to M. tuberculata. M. sculpturalis has the 

 abdomen slightly metallic. 

 Gronoceras catulus sp. nov. 



d 1 . Length about 15 mm., gray, like a small G. felina 

 (Gerst.); in all respects nearly as in felina, but very much 

 smaller, with the hair of the abdomen, between the bands, 

 pale like the bands, though less dense (some long black 

 hairs intermixed just before the bands), so that the abdomen 

 appears much less distinctly banded than in feli?ia. Friese 

 describes two smaller species allied to G. felina, namely 

 laminata and armatipes ; laminata male differs at once from 

 catulus by the simple legs and the color of the thoracic hair ; 

 armatipes male has red mandibles, and the abdomen seems 

 to be different. 



Hair of face arranged and colored as in felina, yellowish-white with 

 some dark hairs intermixed; mandibles black, formed as in felina, 

 with the same large lobe beneath, but somewhat elbowed about the 

 middle ; blade of maxilla striate as in felina ; antennae black, third 

 joint shorter than fourth, apical part of flagellum grooved beneath ; 

 hair of head and thorax above white mixed with black, the black less 

 abundant than in felina, the whole effect paler; wings clear, a little 

 dusky at apex ; as in felina, the b. n. falls short of t. m. ; legs formed 

 and colored (including hair) as in felina; anterior coxae with two 

 spines, one long and one short ; anterior tarsi flattened, yellowish, the 

 basitarsus with a dusky spot as seen from above, but from beneath it 

 is intense black on a white ground, ocellus-like ; lateral hair-fringe 

 largely blackened ; middle tibia? with long white hair behind ; middle 

 tarsi with a great fringe of dark fuscous hair, spreading on either 

 side ; hind tibiae with dark fuscous hair behind ; claws bifid ; apex of 

 abdomen, as in felina, with long white hair, and a longer black brush, 

 and the usual pair of long stout spines.
