 from striate on basal half to finely rugulose on apical half. 



Black. Anterior femora, excepting base, apex of median femora, the four an- 

 terior tibiae entirely, and posterior tibiae with a broad annulus rufous to ferrugi- 

 nous. Tarsi dark brown to black. Abdomen with a yellowish spot bordering on

Two 9 9 . One July 29 (T. D. A. Cockerell). 



Agathis parvus n. sp. — Metathorax with two longitudinal carina?, the 

 space between narrow and rugulose. Second abdominal segment with a semi- 

 circular disk at base, defined by impressions. 



9 Length 3.5 mm. Head entirely polished, apparently impunctate, length of 

 clypeus less than length of malar space. Antennae covered with a very short pu- 

 bescence, the joints not easily distinguished. Dorsulum polished. Mesopleurse 

 polished, with a deep oblique fovea. Metathorax on disc laterally with a polished 

 space, otherwise rugulose. Areolet poorly triangular, the cubiti not exactly con- 

 tiguous on the radius. Space between basal and transverse medial nervure on 

 the medial nervure a little greater than the length of first abcissa of radius. 

 Wings subhyaline, stigma and costal nervure almost black, nervures pale brown, 

 those on basal half of wing testaceous. Abdomen polished, hasal segment indis- 

 tinctly sculptured, ovipositor one-half again as long as abdomen. 



Black. Apical half of anterior femora, apex of median femora and the four 

 anterior tibiae entirely, varied from brownish-rufous to brown, posterior femora 

 partly dark brown, the tibiae with a brownish annulus medially. 



% Length 3.5 mm. Differs only in the less defined longitudinal area of meta- 

 thorax, the more truly triangular areolet and lighter markings of legs.

Microtlus meridionalis n. sp. — Metathorax with all ill-defined longi- 

 tudinal, narrow area ; second and third abdominal segments with impressed 

 lines. 



% Length 3.5 mm. Head polished, face indistinctly sculptured. Parapsidal 

 groove only defined anteriorly for a short distance, a short longitudinal impres- 

 sion extending back from the centre forming a deep dent. Metathorax with two 

 poorly-defined longitudinal lines, space between above the middle very narrow, 

 below diverging until twice broader at base than at apex. The space between the 

 carina? rugulose, a small smooth area to each side, otherwise rugulose. Wings 

 hyaline, with a dark cast, areolet triangular, space between basal and trans-
