Exochilum varicolor n. sp. — Parapsidal grooves only indicated by a 

 slight depression, thickly punctured ; the longitudinal carina on the anterior 

 part of mesopleura short, somewhat distant from the pro-mesopleural suture ; 

 metathorax distinctly excavated between the neck and insertion of coxa?. 



% Length 15 mm. Face with coarse, close and confluent punctures, shining; 

 clypeus shining, with a few large deep punctures, anterior margin with a row 

 of fine separated punctures. Cheeks finely, closely punctured. Dorsulum ante- 

 riorly and posteriorly medially more or less closely, coarsely punctured, the sides 

 polished, with smaller, regular, well-separated punctures, mesopleura? almost 

 uniformly, closely, coarsely punctured. Metathorax dorsally distinctly reticu- 

 late, somewhat concave, with curved, poorly-defined transverse carina?, near the 

 neck, the raised sides with irregular, crude, longitudinal carinas, the sides of the 

 mesonotum not so distinctly reticulate, the mesopleura? opaque, rugulose, the 

 suture hidden. Wing transparent, faintly yellowish fuscous. Stigma and costa 

 yellowish, nervures brown. Head and thorax covered with fine greyish pile, 

 sparsest and longer on metathorax and on pleura?. First two segments of abdo- 

 men polished, the remaining segments dullish sericeous. 



Black. Antenna? somewhat ferruginous. Face, clypeus, labrum, part of scape,

 Trochanters, base of femora, about two-thirds of tibia? basally and tarsi ; yellow, 

 ochreous, rufous and ferruginous. First, second, third, fourth and part of fifth 

 abdominal segments ferruginous, the second with a black line dorsally ; the
