266 FOSSIL COLEOPTERA 



the preservation is rather poor. The insect is dedicated to 

 Charles W. Leng of New York, to whom I am indebted for kindly- 

 help and many favors. 

 Lema lesquereuxi sp. nov. (Plate VI, fig. 13.) 



Form stout. Head wide, apparently short, front rather strongly but not 

 coarsely punctate, vertex with a well marked median longitudinal groove 

 flanked each side by an oblique stria. Eyes of moderate size. Antennae 

 quite stout, the distal joints relatively broader. Prothorax with the sides 

 poorly preserved, surface not visibly punctate even under high magnifica- 

 tion. Scutellum small, triangular. Elytra distinctly punctate in rows, 

 very strongly at base but faintly near the apex, the sutural row disappearing 

 in a stria. Legs stout but not well displayed. Length, to abdominal 

 apex, 4.35 mm.; to elytral apex, 4.15 mm.; of one elytron, 2.75 mm. 



Described from one specimen, with counterpart, collected by 

 myself on the Wilson Ranch, near Florissant, Colorado. The type 

 is in my collection. 



Much smaller than L. evanescens and L. fortior. There is no 

 doubt of the correctness of the generic reference. 

 Luperodes submonilis sp. nov. (Plate VI, fig. 14.) 



Form moderately robust. Head of normal size, eye rounded, antenna 

 slender, first and fourth joints long, second and third, though not very 

 well set up, evidently short, fifth and following longer than either of these 

 two but not equal to the fourth. Prothorax without evident sculpture. 

 Elytron not striate, punctuation fine and scattered, distinct at base becom- 

 ing effaced apically. Legs more or less crushed and distorted but ap- 

 parently about of normal build. Length, in position preserved, 3.50 mm. 



Described from one specimen, with counterpart. The type is 

 in my collection and was found on the Wilson Ranch, near Floris- 

 sant, Colorado. 



Although of small size and fragile build, the fossil is well pre- 

 served and suggests Luperodes at first sight. The reference is 

 borne out in a general way by the sculpture as well as the facies 

 and the antennae are like those of Luperodes except that the short- 

 ening of the second and third joints and those succeeding the fourth 

 is more pronounced in the fossil. It may be compared with the 

 recent L. marginalis from Texas. 



Ulus minutus sp. nov. (Plate VII, fig. 17.) 



Form rather broadly oval. Head of moderate size and deeply sunken 

 in the prothorax, sculpture rough but not very coarse. Prothorax with 

 rounded sides, apex much narrower than the base, flanks coarsely, closely 

 and subconfluently punctured, prosternum moderately broad between
