at apex; humeri rather narrowly exposed at base; punctures not very tine and 

 strong, somewhat sparse. Legs slender. Length 1.8-2.0 mm.; width 0.65- 

 0.8 mm. 



Southern California. Mr. Wickham. 



The male above described has the fifth ventral transversely 

 truncate at apex, the disk impunctate and polished toward apex 

 and with a few slender black hairs in the middle toward base, the 

 third with a small subapical and the fourth with a large median 

 patch of stout black spinules radiating from the median line. 

 The female has the bod^' more slender than the male, with finer 

 pubescence, less transverse prothorax and still smaller head, the 

 the fifth ventral broadly and feeblj^ arcuate at apex, and the ab- 

 domen evenly cinereo-pul)escent throughout. Three specimens. 



37. T. fallax n. sp. — Elongate, subparallel, moderately convex, polished, 

 black with a slight seneo-piceous tinge; legs black, the tibise except near the 

 base and the tarsi piceous-brown ; antennae piceous-black, the first and eleventh 

 joints black; pubescence rather long, subdecumbent, etiual and without erect 

 setic, consisting on the pronotum and elyti'a of brown and cinereous hairs con- 

 fusedly intermingled, moderately coarse and not very dense. Head nearly 

 four-fifths as Avide as the prothorax, strongly but sparsely punctate, feebly 

 rugulose toward base, the impressions strong and widely separated by the im- 

 punctate convexity, the supra-antennal ridges rather pronounced; epistoma 

 very short, not at all pale or coriaceous ; labrum pale at apex, short and broad, 

 circularly rounded; mandibles pale in the middle; eyes large, only moderately 

 prominent, extending to the base; antennte distinctly longer than the pro- 

 thorax, gradually incrassate, the outer joints clothed densely and uniformly 

 with fine short erect cinereous pubescence and also with a few long setie, the 

 fifth joint much wider than the fourth, but subequal to the sixth, tenth trans- 

 verse and almost symmetrical. Prothorax one-half wider than long, the sides 

 almost straight and parallel from the apex to basal two-fifths, then convergent 

 and straight to the basal angles which are very obtuse but not roiuided ; apex 

 rectilinearly truncate throughout, much wider then the base, the angles right 

 and only slightly rounded ; disk finely but strongly, sparsely perforato-punc- 

 tate, coarsely reto-rugose but shining toward the sides, the punctures larger 

 and with elevated edges toward apex; interspaces even and polished; marginal 

 fringe composed of long blackish hairs. Eliiira two-thirds longer than wide, 

 slightly wider than the prothorax, parallel, obtusely parabolic at apex, broadly 

 sinuate at base, rather finely and somewhat sparsely punctate, the marginal 

 fringe composed of rather l<mg even piceous and not very close-set hairs. Al- 

 (lomeii and legs rather densely cinereo-puliescent. Length :>. 1 mm.; width 

 L2o mm.
