118 Mr. Smith's Essay on the Genera and 



suit either this, the preceding, or following species ; therefore 

 until the typical specimen can be examined I retain Nylander's 

 name for the species. 



Sp. 3. Myrnuca Icemnodis. 



Foemina. — Sordide testaceo-ferriiginea, sparse flavido-pilosula ; 

 capite, pronoto, scutello abdomineque supra et infra in medio 

 fuscescentibus ; capite thoraceque longitudinaliter striatim-ru- 

 gulosis ; metathorace spinis brevibus validiusculis : nodis pelioli 

 sublajvibus ; alis hyalinis. 



Operaria. — Testaceo-ferruginea, sparse flavido-pilosula, capite 

 supra abdominisque dorso medio et macula ventrali plus minusve 

 fuscescentibus ; capite et thorace longitudinaliter striatimru- 

 gulosis; metatlioracc spinis binis validiusculis; nodis petioli 

 sublsevibns. 



Mas, — Nigro-fuscus nitidus, sparse flavido-pilosulus ; niandibulis 

 tarsisque pallide testaceis ; antennis scapo valde elongate, me- 

 tathorace inermi, tuberculis utrinque sub-obsoletis ; antennis, 

 troclianteribus, tibiis abdomineque plus minusve conspicue

Female. — Length Sg lines. Fusco-testaceous : the head dark 

 fuscous, the mandibles and antennae pale testaceous, the apical 

 joints more or less ferruginous ; the thorax above usually rufo- 

 testaceous, sometimes only the scutellum; the nietathoracic spines 

 short, stout and acute, slightly divergent ; wings hyaline, the ner- 

 vures pale rufo-testaceous, the stigma slightly fuscous ; the an- 

 terior node smooth and shining above, posteriorly, as well as the 

 second node, obsoletely roughened. Abdomen smooth and 

 shining, more or less fuscous above, and having sometimes a fuscous 

 spot beneath ; the scape of the antennae attenuated at the base, 

 and slightly bent. 



JVorker. — Differs very slightly in any respect from the female, 

 except in being smaller: the mandibles are ferr\iginous, and the 

 nodes of the abdomen faintly rugose. 



Male. — Length 2 lines. Dark luscous, the head less shining 

 than the thorax and abdomen, and obsoletely rugose ; the man-
