G52 . MK. E. J. MIEKS ON THE 



the spiues coalescent at base, and then divergent. A prominent 

 prffioenlar and postocnlar spine. Basal joint of antennae consi- 

 derably enlarged. Merus joint of outer maxillipedes entire at 

 its distal end. Ambulatory legs of moderate length. Type 

 Loxorlnjnclius granclis, Stimpson. 



*LiBiDOCLEA, M.-Udwards. Kostrum prominent, not deilexed 

 and emarginate at its distal end. Merus joint of outer maxilli- 

 pedes notched at its distal margin. Legs rather long. Type Libi- 

 doclea granaria, M.-Edw. & Lucas. 



This genus is closely allied to Lihinia in the family Peri- 

 ceridse. 



DoCLEA, Leacli. Carapace orbiculate-triangular, or orbicu- 

 lato. Eostrum usually very short, emarginate. No preeocular 

 spine. Basal antennal joint but moderately enlarged at 'base, 

 Legs very long and stender. Type Doclea Bissonii, Leach. 



This genus is closely allied to JEgeria, and marlss the transition 

 to that genus of Maiidse. 



Subfamily 5, Stenocionopin^. 



Eyes elongated and retractile, partly concealed by the prfcocukr spine, 

 which is very greatly elongated. Basal antennal joint considerably en- 

 larged throughout its length. 



The rostrum is composed of two spines. Carapace somewhat oblong 

 and posteriorly prolonged. The articulation of the merus joint of the 

 outer maxillipedes with the preceding joiut is often very peculiar. 



The enlarged basal antennal joint marks the approach of this 

 subfamily to the Maiidee. Were the upper orbital margin as 

 well developed in all the genera as in Tyclie, it would be better to 

 constitute it a subfamily of that group, 



*STE]srociO]sroPS, Latreille. Upper orbital margin behind prse- 

 ocular spine not developed. Posterior lobe of the carapace 

 simple. Merus joint of outer maxillipedes greatly produced 

 and acute at its antero-external angle, and with a notch on its 

 inner margin for the insertion of the fourth joint. Type Steno- 

 cionops cervicornis (Herbst). 



^Stilbognathus, ?J. Martens. "Faciea of Stenocionoj^s. Ischium 

 joint of the outer maxillipedes with a longitudinal pit on its outer 

 surface which is covered with bristles ; merus joint convex and
