92 HYMENOPTEEA. 



c. Wings hyaline, with a moderately large fascia stretching across from the cubitus. 



(Species 37.) 



37. Smicra maculipennis. 



Testacea ; antennarum apice, mesonoto, abdominis dorso, petiole pedibusque posticis nigro-maculatis ;. alis

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



The body is covered with a long white pubescence ; the head is finely punctured ; 

 pronotum, mesonotum, and metapleura coarsely punctured ; abdomen smooth, shining. 

 The head is only slightly hollowed in front ; between the antennae it projects broadly 

 and bluntly. On the mesopleura is an oblique broad hollow, which is transversely 

 striated; the pronotum is of nearly equal breadth throughout above; the sides are 

 impunctate, as is also the mesopleura in front of the hollow space. The scutellum is 

 margined, but not very strongly, behind, where it is somewhat sharply rounded ; the 

 metanotum slopes gradually to the petiole ; it is blistered above. There is a central 

 keel which bifurcates in the middle ; the other keels are rather indistinct. The petiole 

 is a little more than one third of the length of the posterior coxae ; it is striated and 

 ridged at the sides. At the apex of the posterior coxae is, in the centre, a large tooth, 

 and nearer the apex and on the inner side of it is a smaller tooth. The coxae are 

 longer than the femora ; the teeth on the latter are numerous and minute. The 

 antennae are thickened towards the apex ; the scape is hollow at the side, the two apical 

 joints are black. The greater part of the middle lobe of the mesonotum, parapsides, 

 the apex of the scutellum in the middle, metapleura, and metasternum in part, the apex of 

 posterior coxae (where they are transversely striated), the posterior femora on lower side y 

 and the middle of the abdomen, black. The four anterior legs are pale testaceous. 



3. Body yellowish or testaceous, without any black markings. 

 (Species 38-40.) 

 The three species known from Central America of this type of coloration may be 

 recognized by the following Table : — 



Petiole long, narrow, half the length of posterior coxse ; a small fascia 



at cubitus .................... (38). fulvo-variegata. 



Petiole short, thick, not half the length of coxse ; no fascia at cubitus : 

 Abdomen acuminate at tip; sheath of ovipositor projecting; pos- 

 terior femora with 19 teeth (39) fulvo-maculata. • 



Abdomen obtuse at tip ; sheath of ovipositor hidden ; posterior 



femora with 12 teeth (40) obtwiventris. . 



38. Smicra fulvo-variegata. 



Flava, fulvo-variegata <J, flavo-variegata $ ; abdomine fulvo, flavo-maculato, flagello antennarum fusco, 



femoribus posticis 17-19 dentatis ; alis hyalinis, macula substigmaticali fusca, nervis fuscis. 

 Long, fere 5 millim.
