]>unctate, the eyes prominent ; antennae slender, scarcely as long 

 as the head and protliorax, feeblv thickened toward apex, the pe- 

 nultimate joint fully as long as wide, the last short, second and 

 third equal and but slightly shorter than the first which is thicker. 

 Prothorax not quite as wide as the head, a little longer than wide, 

 acutely constricted somewhat behind basal third, the punctures 

 fine and very sparse except toward base, where they become 

 coarse and very dense, the two transverse tubercles more or less 

 distinct, the surface before them apparently somewhat impressed. 

 Elytra elongate, very nearlv twice as long as wide, twice as wide 

 as the prothorax, quite distinctly wider at the middle, the punc- 

 tures coarse and sparse ; pubescence spai'se, short, pale through- 

 out. Length 2.5-2.8 mm.; width 0.8-0.9 mm. 



California seacoast from San Diego to San Francisco. The 

 apex of the abdomen is generally pale, and, in the male, the fifth 

 segment is distinctly longer than the fourth, rounded and not at 

 all truncate at apex, with the surface A'ery obsoletel}' and broadly 

 impressed along the middle, and gradually just visibly reflexed 

 toward tip, the genital segment with a small feeble and circularly 

 rounded apical sinuation, and a transverse discal impression, the 

 apical edge fringed with stiff hairs. 



In this species the male intromittent organ is quite different 

 from that of texanus and mimus ; it is not quite so long, and 

 the dorsal corneous sheath has the sides nearly straight and 

 feebly convergent from the base almost to the apex, where it be- 

 comes abruptly narrowed and very feebly bent downward, the 

 narrow ligula short, subparallel, obtuse but not distinctly en- 

 larged at apex. The intromittent duct proper, lying beneath the 

 sheath, is slender, simple, coriaceous and extends slightly beyond 

 the apex of the sheath. 



5. T. franciscaiius n. sp. — Moderately stout, convex, shining, pale 

 rufo-testaceous, the entire under surface of the hind body, and a moderately 

 large cloud near the middle of each elytron, black; antennae and legs pale 

 throughout. Head rather longer than wide, convex, strongly and rather 

 closely punctate; eyes moderately large, prominent, situated somewhat before 

 the middle of the medial length; antennte somewhat stout, distinctly iucras- 

 sate, scarcely as long as the liead and prothorax, the tenth joint about as long 

 as wide. 1'rofhorn.r ample, not distinctly narrower than the head, a little 

 longer than wide, rather feebly convex toward the middle, finely but strongly 

 punctate, the punctures somewhat sparse anteriorly l)ut becoming dense to-
