In size, coloration, and punctuation this species does not differ much, if at all, from 

 the preceding ; the only differences of any importance that I can find between them 

 are that the scutellum is not raised into a sharp peak in the centre, it being flat along 

 its entire extent, and traversed by two or three carina?, the sides being also keeled ; that 

 the third abdominal segment is shorter than the following segments together (the 

 opposite being the case in /. nigriceps), and that the metathoracic areee are all clearly 

 defined, and the pronotum not transversely striated.

Hab. Costa Rica, Cache (Bogers). 



Head smooth, shining ; the face and sides with some scattered punctures. Meso- 

 notum shining, smooth, finely punctured, the punctures wide apart. Pleura? finely 

 punctured, striated posteriorly. Scutellum fiattish, smooth, shining, indistinctly punc- 

 tured ; postscutellum smooth, shining, impunctate. Base of the metanotum smooth, 

 shining, impunctate ; the rest irregularly reticulated and striated ; the areee not very 

 clearly defined ; the metanotum has but a gentle slope, and the centre behind is a little 

 hollowed. Petiole smooth, shining ; postp'etiole, and the second and third segments, 

 longitudinally striated ; the rest of the abdomen impunctate, smooth, and shining. 

 Gastrocceli large, deep, transverse, shining in the centre; the sides striated. The 

 mandibles, palpi, labrum, clypeus, and the lower orbits of the eyes are yellow, the 

 black extending down the centre of the face from the antennae to the clypeus. The 

 prosternum is yellow, as is also the hind portion of the mesothorax and the whole of 

 the metathorax. The four anterior tibiae and tarsi are entirely black behind; the 

 anterior femora are black, except at the base and apex ; the middle femora have about 

 the apical half black; the posterior tarsi are entirely black, as are also the hind 



* The localities " Guatemala and Panama," given for this species (he. tit.), are erroneous. I have only seen 

 it from Costa Rica as yet.
