T. squamosa n. sp. — Oblong-oval, strongly convex, piceous-black ; 

 integuments shining. 



Male. — Head densely punctate, clothed with long erect hair and shorter 

 recumbent squamiforni hairs, the vestiture of the clypeus a little sparser; 

 vertex not tuberculate ; clypeus broadly, feebly sinuate, strongly reflexed, 

 the angles obtuse and but slightly marked ; antenn* moderate, the club 

 nearly three-fourths as long as the stem ; fourth joint of the maxillary palpi 

 very long, fully one-third longer than the antennal club, with a narrow, very 

 deep, parallel-sided groove throughout the length. Prothorax one-half wider 

 than long, the apex broadly, evenly emarginate, fully one-half as wide as 

 the base, the latter broadly subangulate ; sides broadly subangulate, the 

 margins strongly reflexed toward base, feebly serrate ; apical angles narrowly 

 rounded, basal rather obtuse and broadly rounded ; disk very strongly con- 

 vex, narrowly impressed along the middle, coarsely, densely punctate, clothed 

 with long erect hair and long robust recumbent and squamiform pubescence, 

 which is dense along the median line except near the base. Scutellum densely 

 punctate and squamose. Elytra one-third longer than wide, one-third wider 

 than the prothorax, subparallel; sides feebly arcuate ; humeri rounded ; apex 

 broadly subtruncate ; disk finely, somewhat densely punctate and clothed 

 with distinct pointed scales. Pygidium slightly wider than long, convex, 

 deusely clothed with long narrow scales and short hairs. Abdomen somewhat 

 densely clothed with elongate scales and short hairs, the sterna densely pilose. 

 Legs moderately slender ; hind tarsi fully as long as the tibise, with the tooth 

 of the anterior claw nearly twice as long as that of the posterior. 



Female. — Larger and stouter than the male, the vertex tuberculate, the 

 antennal club small and oval, the fourth joint of the maxillary palpi three- 

 fourths as long as the latter, elongate-triangular, with a narrow deep elongate 

 groove not quite attaining the base or apex ; pygidium much wider than long ; 

 anterior tibiae robust ; hind tarsi two-thirds as long as the tibiae, the teeth of 

 the claws small and moi'e nearly equal. Vestiture throughout consisting of 

 minute recumbent hairs, sparsely j^laced, with erect hair as in the male.

California (Sau Luis 01)ispo Co.). 



A distinct species, somewhat related to harfoi'di, but easil}^ dis- 

 tinguishable by many characters of both sexes. The tubercle of 

 the vertex is, throughout the genus, partieularl}^ characteristic of 

 the female.
