rior transverse impression distinct ; basal impressions small, distinct ; base trun- 

 cate; sides with the margin very narrowly reflexed, arcuate in front, oblique 

 behind, distinctly sinuate in front of the hind angles, which are rectangular, not 

 carinate. Elytra oblong-ovate, subparallel, slightly wider than the thorax, very 

 finely striate; tiie two inner striae usually deeper, the third and fourth feeble, 

 the outer obsolete ; first dorsal puncture about the middle, the second at the tip 

 of the recurved portion of the sutural stria; intervals Hat. Head and thorax 

 beneath rufo testaceous, the abdomen piceous. Legs testaceous. Length .09-. 11 

 inch ; 2.25-2.75 mm. 



This .species bears a close resemblance in general facies to T. mor- 

 (h.r Lea, but may 1k j , distinguished by its larger and more promi- 

 nent eyes, and by the thorax less narrowed behind. 



Described by Chaudoir from Texas. It is known to me from 

 several localities in that State, and also from numerous points along 

 the coast of New Jersey. 



30. T. occultator Casey. — Form moderately elongate, subdepressed. Color 



var.ving from lufo-ferrugi neons to piceous, shining, the elytra usually slightly 

 darker than the thorax, and often with a subhumeral blotch and a smaller sub- 

 marginal spot about one-third from apex paler, the spots usually ill defined ; 

 inflexed portion of the elytra paler. Head as wide as the thorax at apex ; frontal 

 grooves distinct, extending backward behind the middle of the eye; eyes large, 

 prominent; antenna? scarcely one-half as long as the body, piceous, the three 

 basal joints paler; palpi rufous. Prothorax very slightly narrower at base than 

 apex, about one-half wider than long, subquadrate; apex truncate; anterior 

 transverse impression obsolete, the posterior distinct, finely punctulate; median 

 Hue very fine or nearly obsolete, abbreviated at each end ; basal impressions 

 small, deep; base truncate; sides with the margin very narrowly reflexed, more 

 widely towards the basal angles, arcuate in front, sinuate behind ; hind angles 

 rectangular, not carinate. Elytra about one-half wider than the thorax, oblong- 

 ovate, with a sutural and two or three dorsal stria? ; striae impunctate, the sutural 

 deeper, the others abbreviated at eacli end and becoming finer externally; first 

 dorsal puncture about the middle, the second at the tip of the recurved portion 

 of the sutural stria; intervals flat. Body beneath piceous or rufopiceous, the 

 head and thorax usually somewhat paler. Legs testaceous. Length .09-.12 inch: 

 2.25 3 mm. 



This species is subject to considerable variation in color. Captain 

 Casey's type was evidently, from his description, slightly immature. 

 Most specimens from the more northern portions of its range have 

 the elytra unicolorous, rarely with faint traces of the paler markings 

 noted above. These are usually well marked in examples from 

 Florida, while in those known to me from Texas the two spots are 

 united. Two specimens from Florida have the head and thorax 

 rufo-ferrugineous and the elytra piceous, but all these forms are con- 

 nected by intergrades in the series before me.
