slender, clistiuetly longer than the prothorax, the penultimate joint nearly one. 

 half wider than long, fifth and seventh scarcely enlarged. Prothorax short and 

 transverse, three-fourths wider than long, gradually and only slightly nar- 

 rowed in apical half, the basal angles acute and everted; apex transversely 

 truncate, anteriorly oblique at the sides, tlie apical angles anteriorly promi- 

 nent but rather blunt; disk smooth and polished, finely and sparsely punctate 

 througliout. Etijtra sliort, scarcely more than one-tliird longer than wide, 

 fully two-fifths wider than the prothorax, parallel and straight at tlie sides, the 

 apex extremely liroadly and obtusely but evenly rounded; side margins some- 

 what reriexed, the vertical fianks impressed ; humeri slightly tumid ; disk finely, 

 evenly and moderately closely punctate, Ahdotnen finely and closely punctu- 

 late, the legs somewhat stout; hind tarsi distinctly shorter than the tibise. 

 Length 2.9 mm.; width 1.6 mm. 



California. 



The only known specimen of this species is likewise a female, 

 and is from an unrecorded part of the State. The species is re- 

 markabl3- distinct in the prominent apical and acutel}' everted 

 basal angles of the prothorax, and in the ver}" short broad form 

 of the bod}-. The epiplenro? are not much wider than in the or- 

 dinary species of the genus, and are gradually narrowed behind, 

 but they are nevertheless somewhat intermediate between the 

 usual type and the broad horizontal form characterizing the 

 genus Eudas3'tes.

 a feeble seneous lustre; legs and antennte throughout black; pu-
