 Systolodes brevicornis sp. n. 



9 . — Lenjith 1.5 ram. Black, shining, feebly shagreened, with traces of very 

 shallow umbilic.ate punctures; knees, anterior tibiae, except a blotch outwardly, 

 and all tarsi, except sometimes the posterior pair, honey-yellow. Antennae 10- 

 jointed, short, suhclavate, black, the first joint of funicle slightly the longest 

 joint, tlie four following about equal, quadrate, club fusiform, 3 jointed, as long 

 as the last three joints of fuuicle united. Wings hyaline, the nervures light 

 brown, the marginal not longer than the stigmal, the latter ending in a knob 

 with a slight uncus. Abdomen globose, subsessile, not longer than the thorax, 

 the first four body segments very nearly equal, the following retracted within 

 the fourth, and not visible, or only the smallest particle visible. 



^. — This sex differs from the 9 only as follows: The antennae are longer, 

 with long, white hairs; the pedicel very small ; the funicle only 4-jointed, the 

 joints excised at apex, the first the longest, about two and a half times as long 

 as wide, the following gradually shortening, the last being only a little longer 

 than wide; club S-joiuted, as long as the last two funicular joints united.

Described from specinieDs received some years ago from Mr. W. 



Hague Harrington and Abbe Provancher. This genus apparently 



connects Systole Walk, with Bruchophagus Ashrn., and could be 



easily mistaken for speciinens of Bruchophagus (Eurytoma) fimebris
