SPILOCHALCIS APAIIS, new species 



Figure 10, c 



In having the antennal scape short and the flageUum stout, while 

 the head, from the dorsal aspect, is almost one-half as long as wide, 

 this species agrees with S. juxta (Cresson) but differs in that the 

 left mandible has only two teeth instead of three, the dorsum of the 

 thorax is flattened, and the metacoxae and femora are mmutely 

 shagreened instead of glabrous. 



Descriptio7i.-S>\2.c^; the following areas yellow: Frons laterad 

 of scrobe cavity, genae, dorsal meson of pronotum, lateral margms of 

 mesopraescutum and mesoscutum, mesal angles of axillae, basal and 

 lateral margins of mesoscutellum, apices of profemora and meta- 

 f emora, all tibiae and tarsi, and subapical spot on outer ventral margm 

 of metaf emora; the following areas orange: Scape, pedicel, and seg- 

 ments 3 to 5 of antennae, narrow band across vertex, dorsolateral 

 areas of pronotum, anteromesal areas of mesopraescutum, small mesal 

 spots on lobes of mesoscutum, subbasal area of mesoscutellum, outer 

 dorsal side of metacoxae, outer surface of metafemora, apex of 

 propodeum, and transverse dorsal stripes on abdominal segments 



3 and 4. . 



Female: 2.5-3 mm. Apex of antennal scape not quite reaching 

 level of ventral margin of anterior ocellus, pedicel one-third longer 

 than segment 4, ring segment one-sixth length of pedicel, segment 5 

 one-fifth longer than 4 and slightly longer than 6, 6 to 11 equal, 12 

 and 13 slightly shorter; scrobe cavity deep, and inconspicuous carina 

 present on ventral half of each lateral margin, a short transverse 

 carina present in scrobe cavity just ventrad of anterior ocellus ; inter- 

 antennal projection strongly produced cephalad but without a carina 

 or lamina, frons deeply and densely pitted on area laterad of scrobe 

 cavity, scatteringly punctured on lateral areas ventrad of antennal 

 bases, impunctate on meson, pubescence long, scattered ; frontal ten- 

 torial pits located just laterad of antennal bases; width of malar space 

 one-third height of compound eye ; f rontogenal suture slightly arced, 

 almost straight; combined widths of compound eyes four-fifths or 

 slightly more width of interocular space at level of antennal bases; 

 left mandible with two teeth, right with three; width of interocellar 

 space two and two-fifths times the diameter of posterior ocellus; head, 

 from dorsal aspect, slightly less than one-half as long as wide. 



Dorsum of thorax (fig. 10, c) flattened, thickly covered with shal- 

 low, irregular punctures, area at anterior margin of mesopraescutum 

 not punctured but shagreened; pubescence long, white or yellow; 

 anterolateral angles of pronotum carinate, carina of anterior dorsal 

 margin interrupted on mesal one-third; parapsidal furrows distinct; 

 prepectus narrow, just reaching tegula; apex of mesoscutellum with
