In my opinion but one species exists in our fauna : 



T. croceicollis Menet.— Length .24— .32 inch ; 6—8 mm. 



Male. — The anterior tarsi are slightly dilated the first three joints biseriately 

 lamellate beneath. The middle tarsi are scarcely at all dilated and with traces 

 of lamellae on the second and third joints only. The anal segment has one seta 

 each side. 



Female. — Tarsi slender hairy beneath. Anal segment with two setae each side. 

 Occurs on the Pacific coast from San Diego to Oregon, thence east- 

 ward to Montana, Utah and possibly Texas. 



EUPROCTUS Solier. , 



Mentum emarginate, without tooth, epilobes not prominent. Ligula corneous, 

 cuneiform, truncate and quadrisetose at apex, paraglossse membranous, prolonged 

 across the 'front of the ligula and ciliate, palpi with terminal joint somewhat 

 triangular. Maxillary palpi with last joint as in the labial. Labrum transverse, 

 not emarginate in front. Mandibles with distinct scrobe externally. Antennae 

 with the first three and the base of the fourth joint glabrous. Head gradually 

 narrowed behind the eyes to a neck. Thorax truncate at base, slightly oblique 

 near the hind angles which are slightly reflexed. Tarsi slightly flattened above, 

 somewhat pubescent, the first joint of the posterior not as long as the next three, 

 fourth joint on all the feet deeply bilobed. Ungues pectinate. 



Notwithstanding that Chaudoir places Euproctus in the Callidides and 

 TecnopMlus in an uncharacterized group Mimodromiides, there does not 

 seem any valid reason for separating them very remotely. 



One species occurs in our fauna. 



Eu. trivittatlis Lee. (Onola). — Bright rufo-testaceous, elytra with a common 

 sutural vitta expanded slightly at middle and a submarginal band extending along 

 the apex to the suture, piceous. Length .20 inch ; 5 mm. 



Male. — Anterior tarsi feebly dilated, the first three joints biseriately lamellate- 

 papillose, the fourth pubescent. Anal segment with one seta each side. 



Female. — Tarsi pubescent beneath. Anal segment bisetose each side. 

 Collected by Mr. A. Bolter in Florida, at Fort Capron. 



CALLIDA Dej. 



This genus is one of the largest in the truncatipenne series, Chaudoir 

 recognizing very nearly one hundred species after separating a number 

 of genera of very doubtful value. 



The species in our fauna, although not numerous, have not escaped 

 division and the two genera are separated by characters which seem to 

 have very feeble value and are as follows : 



Callida. — Tarsi with a median groove on the upper side more or 

 less apparent. In the male the anterior tarsi are always, the middle 

 very often dilated, the joints beneath biseriately lamellate-papillose, in 

 the middle tarsi the lamellae are always wanting on the first joint, and 

 sometimes on all the joints. 



Spongoloba. — Tarsi neither sulcate nor impressed. In the male
