28 NATURAL HISTORY BULLETIN 



Station number 17. One specimen, collected by Geo. N. Rohwer. The 

 type is in the Museum of the University of Colorado. 



This insect looks very much like Lema evanescens but is more 

 finely punctured and has a distinct scutellar stria. 



]\Ietachroma Lee. 



M. FLORISSANTENSIS n. sp. (Plate V, Fig. ?.) Form moderately el- 

 ongate, probably about as in the recent M. calif ornicum. Head and pro- 

 thorax very poorly preserved, not showing the sculpture nor fully main- 

 taining the original shape. Antennae long and slender, reaching to near 

 the middle of the elytra. Elytra somewhat overlapping along the suture 

 but not sufficiently to seriously obscure the punctuation which is rather fine 

 and arranged in nearly regular striae, fading towards the apex as in recent 

 species of this genus. Length from front of prothorax, as preserved, to 

 abdominal apex, 5.2.5 mm. In life, with the head normally extended, it 

 probably reached a length of about 1 mm. more. 



Station number 13B. One specimen, collector not specified. The type 

 was received directly from Professor Cockerell and is in the Museum of 

 the University of Colorado. 



There is little doubt in my mind as to the correctness of the 

 identification. The first stria, outside of the scutellar, has been 

 partly obliterated by the overlap, otherwise the sculpture is 

 strikingly like that of M. calif ornicum. 



Bruchus Linn. 



B. HENSHAWi n. sp. (Plate VII, Figs. 1, 14.) Form moderately robust 

 but less so than in B. dormescens. Head of normal size, finely and closely 

 punctured, somewhat more coarsely on the front. Eye a little smaller than 

 in most of the recent species with which I am acquainted. Antenna reach- 

 ing about to the prothoracic hind angle, incrassate towards the tip but 

 not strongly nor rapidly, the joints not serrate so that the outline is nearly 

 even. Prothorax rather finely punctured, the punctures circular, larger than 

 those of the head, rather distant except near the sides where they are con- 

 siderably closer together. Hind angles rounded, median lobe not well 

 marked. Elytra overlapping somewhat so that the exact shape is doubtful, 

 but each seems to have been marked with nine striae, the outer stria in- 

 curved at the humerus. The striae are not deep but are strongly uniseri- 

 ately punctate, the punctures rounded and rather closely approximate 

 though not confluent, wider than the stri«, as shown in the detail figure, 

 interspaces broad, flat, strongly and rather closely obliquely rugose. Ab- 

 domen poorly preserved, the sculpture not definable. Hind leg, the only 

 one visible, showing a moderate post-median femoral tooth, tibia slightly 

 curved and apparently carinate. Length, 4.15 mm. 



Station number 14. A single specimen, collector not specified. The type 

 is in the American Museum of Natural History.
