571. I>. laevis. Nigra, prothorace villoso, nitido, parce punctato, ad 

 basin breviter irnpresso et bicalloso ; elytris piceis, rugose puuctatis, di- 

 midium abdominis sequantibus, apice rotuudatis, longe dehiscentibus,

Illinois ; the only specimen in my collection has the last ven- 

 tral segment triangularly excavated, and hairy as in D. ventralis, 

 which I consider as the ? of D. tenuipes Hald. It differs by the 

 nearly smooth thorax, and by the elytra rather longer, narrowed 

 and more dehiscent behind the middle. 



* The following species is mentioned by Chevrolat, Ann. Ent. Soc. Fr., 

 1862, p. 25(3, as M. pusilla, which it replaces in the Antilles. 



Methia punctata. Fusco testacea, antennis femoribus elytrisque 

 pallidi, his vitta obliqua a basi ad medium, altera submarginali, apiceque 

 obscuris ; prothorace dense punctato, latitudine longiore, lateribus fere 

 recti s, postice trans versim irnpresso, dorso haud calloso. Long. 7 — 10. 



One 9 , San Domingo, Mr. Gabb ; Cuba, Dr. Gundlach. Very similar to 

 M. pusilla, but the sides of theprothorax are scarcely dilated at the middle, 

 the front transverse impression is wanting, the posterior constriction is 

 less deep, there are no dorsal callosities, and the elytra are comparatively 

 shorter. The color of the head and prothorax is light and dark brown 

 mixed ; the elytral vittse are connected transversely near the base, and 

 about the middle, but frequently disappear, leaving only a humeral cloudy 

 spot. The wings as in all the species of the tribe are very imperfectly- 

 folded at tip.
