88 HYMENOPTEBA. 



either side below each antenna. Antennae thick, the joints subequal and not pilose, 

 but with the surface rough. The mesonotum is covered uniformly all over with 

 moderately deep and closely set punctures ; those on the collar are not so distinct ; both 

 are covered with longish black hairs. Pleurae smooth and shining, impunctate ; there 

 is a narrow, transverse, black line behind the collar, a broader longitudinal one in the 

 centre of the mesonotum, which becomes narrower as it reaches the pronotum ; at its 

 apex, and in front of the scutellum, is a broad transverse line * ; there is a somewhat 

 triangular or rather pear-shaped mark at the apex of the scutellum, and two marks on 

 the postscutellum, all black. The scutellum is broadly rounded, with a broad margin 

 above and beneath ; the sides smooth, shining. The metanotum has broad irregular 

 reticulations ; the metapleura with indistinct reticulations. The petiole is a little more 

 than half the length of the posterior coxae, which have the teeth nearly of the same 

 size, except the basal tooth, which is a little longer and sharper, and the apical teeth, 

 which are a very little shorter, blunter, and more closely pressed together. 



31. Smicra octomaculata. (Tab. V. fig. 8, thorax.) 



Flava ; antennis, scapo (subtus excepto), maculis sex mesonoti, apice coxarum posticarum, geniculis posticis, 



tibiarum posticarumque apice nigris, femoribus posticis 15-dentatis. 

 Long. 7-8 millim. 



Hab. Panama, Bugaba (Champion). 



The scape reaches to the upper ocelli, compressed beneath ; flagellum longer than 

 thorax. Front not very deeply excavated; lower part of head behind black. There are 

 four broad longitudinal marks at the base of the mesonotum, a broad transverse one 

 on the base of the scutellum and extending beyond it, a spot on the apex of it, a spot 

 on the upperside of the coxae at the apex, and the knees and apex of the posterior 

 tibiae, black. The teeth are small and blunt. Petiole about one half longer than broad. 

 Abdomen as long as the thorax, acute at the apex; the terebra projecting, black. 

 Thorax covered closely with round, shallow punctures ; the pleurae obsoletely punctured. 

 Scutellum broadly bordered behind. In front of the prothorax is a large black spot. 



A larger species than 8. maculicollis, and sufficiently distinguished from it by the 

 longer abdomen and ovipositor, by the larger size of the marks on the mesonotum, and 

 by the absence of a spot on the base of the metanotum and the posterior coxae. 



32. Smicra maculicollis. (Tab. V. fig. 7, thorax.) 



Flava; flagello antennarum, macula pronoti, lineis maculisque 4 mesonoti, scutelli apice, macula metanoti, 

 macula ad basin coxarum posticarum, trocbanteribus posticis abdominisque apice nigris; alis hyalinis, 

 femoribus posticis 14-dentatis. 



Long. 5 millim. 



Hab. Panama, Volcan de Chiriqui 3000 to 4000 feet (Champion). 



* I am not sure if this line is continuous, as tbe pin goes tbrougb its centre, and it may be only two 

 disconnected marks.
