hairs. Scutellum minute. Elytra elongate oval, broadest at middle, 

 moderately convex and with rows of feeble distantly placed punctures 

 becoming obsolete towards the apex, intervals with very minute distant 

 punctures, each bearing a slender white recumbent hair. Pectus beneath 

 with a cinereo-pubescent line near the elytral ed<;e, surface nearly im- 

 punctured, smooth shining. Fernora slender mutic. Length .14 inch ; 

 3.5 mm. 



The femora of this species are much more slender than is usual and 

 absolutely devoid of any tooth, and the anterior pair merely very feebly 

 sinuate. One of the most distinct species in our fauna. 



One specimen in the cabinet of Mr. II. Ulke, collected in Maryland. 

 I have not been able to determine, with the specimens at my disposal, 

 whether the sexes are distinguished by the presence of the additional 

 dorsal segment in the male. It is however probable that as in the greater 

 number of MeeorTiynques which I have examined, the males have 8 and 

 the females 7 dorsal ventral segments. 



Magdalis Germ. 

 Our species are few in number and represent all the groups into which 

 the genus has been divided. Four species have simple ungues and two 

 of these have unarmed femora, and all have the thorax without anterior 

 serrature or spines. 



The sexual characters are remarkable. The males have the dorsum of 

 the abdomen with eight segments, the females have one less. This results 

 from the union of the last two dorsal segments so that the female has 

 apparently a much larger pygidium than the male. The pygidium of 

 the male is short, twice broader than long. The antennas of the males 

 are inserted near the tip of the rostrum and in the females very slightly 

 in front of the middle, the rostrum in the males being slightly dilated at 

 tip. Both these latter characters suffer an exception in M. Lecontei, as 

 in both sexes the rostrum is similar and the antennas inserted slightly 

 behind the middle. This might constitute a distinct genus. 



As far as known our species are as follows : 

 Claws simple. Thorax in front not serrate. 

 Femora mutic. 



Body black, elytra with very coarse punctures perforata. 



Body blue, elytra with moderately fine punctures cuneiformis. 



Femora dentate. 



Body blue, thorax widest at base Lecontei. 



Body brown, thorax not wider at base than at middle. imbellis. 



Claws toothed at base. Thorax serrulate or dentate. 

 Mesosternum protuberant. Head elongate conical. 



Scape of antennas not attaining the eyes barbita. 



Mesosternum not protuberant, scape of antennas passing 

 the eyes. 

 Body above totally black. 

 Hind angles of thorax feebly laminiform, disc densely 

 punctured.
