Body beneath black, clotiied with cinereous pubescence, coarsely punc- 

 tate. Antennal fossae deep and large. Prosternum long and moderately 

 broad, tip broad, sub-carinate. Mesosternum completely and broadly 

 divided to receive prosternum. Abdominal segments black or rufous, 

 coarsely punctate and pubescent. Legs rufous. Length .08-.20 inch ; 

 2.5 mm. (Figs. 46, 47, 48.) 



Jfale. Antennae with joints 1-3 large and equal, globular, 3-5 small and 

 globular, G-11 strongly pectinate, forming the club. 



Female. Antennae with joints 1 and 2 almost equal, large, globular, 

 3-7 small, globular, 8-11 forming the club. 



This species may be separated by its entire eyes, the character of the 

 antennae, the large antennal fossae, the broad tip of the prosternum and the 

 widely divided mesosternum. It is of moderate size. 



Occurs everywhere. 



T. sternale, n. sp. Oblong, black, clothed with sparse, black, semi- 

 erect pubescence. Elytra black, with three irregular confluent bands 

 and apical and basal spots of red, bearing whitish pubescence. Head 

 coarsely punctate, sparsely pubescent. Eyes entire, moderately promi- 

 nent. Antennae rufo-testaceous. Thorax coarsely punctate, sides and 

 base bearing whitish pubescence. Elytra black, with three variable rufo- 

 testaceous bands, bearing white or gray pubescence, the\.rest sparsely 

 clothed with black hairs. Body beneath piceous, coarsely punctate, with 

 cinereous pubescence. Antennal fossa moderately deep, occupying all 

 the space between prosternum and lateral margins. Prosternum short, 

 moderately wide, tip convex and acute. Mesosternum deeply incised but 

 not entirely divided. Abdominal segments piceous (variable to rufous), 

 apical margins testaceous. Legs rufous. Length .08-16 inch; 2-4 mm. 

 (Fig. 50.) 



Male. Antennae with joints 1 and 2 large, 3-5 small and equal, 6-11 

 forming a deeply pectinate club ; joints 10 and 11 are usually connate. 



Female. Antennae with joints 1 and 2 large, 4-7 small, 8-11 forming 

 the club. 



The distinctive characters of this species are the entire eyes ; pectinate 

 antennae ; large antennal fossae ; acute tip of prosternum and the meso- 

 sternum only deeply incised. It is the smallest form in the genus. 



Occurs in California, New Mexico, Arizona, Texas, «fec.

 punctured, quite sparsely pubescent. Eyes deeply emarginate in frpnt, 

 not very prominent. Antennae testaceous. Thorax finely punctate, 

 moderately sparsely pubescent. Elytra black, with four irregular bands 

 of red, bearing grayish pubescence, the rest with sparse black pubescence,
