AMERICAN COLEOPTERA. 207 



angular, ninth as long as the five preceding united, tenth a little longer; elev- 

 enth as long as the tenth and a little narrower, oval, rounded at the. tip. In the 

 female the three outer joints are smaller, less broadly triangular, with the outer 

 angle not acute, the tenth joint not longer than the ninth. Head finely evenly 

 densely punctate ; prothorax acutely granulate on the disk, the surface elsewhere 

 finely, densely, simply punctate and alutaceous; elytra closely evenly punctate. 

 Metasternum granulate at sides. Length 3.5-4.5 mm. 



"Two specimens collected in Kentucky by Mr. J. H. Wild." 

 So far as I can ascertain there are no specimens of this species in 

 collections other than the LeConte types. The occurrence of three 

 other species of this genus in California, with none — so far as 

 known — in the intervening territory is a somewhat remarkable 

 instance in distribution, which is, however, closely paralleled in 

 Vrilletta. 



2. M. frontalis Lee. — Oblong-oval, dark brown or fuscous, with fine 

 sericeous prostrate pubescence. Antennte ( % ) with the first joint stouter and 

 curved as usual, second aud third much smaller, elongate, the third a little more 

 slender; fourth and fifth subequal and a little longer than wide, sixth to eighth 

 transverse, together equal to the fourth and fifth united ; ninth and tenth as 

 long as sixth to eighth, and with an inner branch which is subequal in length to 

 joints 1-8; eleventh slender and fully as long as the branches of the two preced- 

 ing joints. In the female the ninth and tenth joints are moderately elongate, 

 triangular, the eleventh elongate-oval. Head densely, finely puuctulate. Pro- 

 thorax granulate at middle of the disk, which is a little prominent posteriorly ; 

 surface elsewhere densely, evenly, rather finely punctate. Elytra finely closely 

 punctate, with somewhat coarser punctures, which tend to arrange themselves 

 in barely visibly impressed lines. Metasternum polished and not very closely 

 punctate at middle, subalutaceons and moderately closely punctate, laterally, the 

 punctures somewhat unequal in size. Ventral surface moderately closely finely 

 punctate. Length 3.25-5 mm. 



Southern California, Santa Barbara (type) ; Pasadena. Occurs, 

 though not common, at the latter place in May and June on Quer- 

 cus agrifolia. 



3. M. vitliiuin n. sp. — Similar in most respects to frontalis, but of somewhat 

 larger size. Antenna? (9?) nearly as in frontalis, but with the ninth and tenth 

 joints a little more elongate, about twice as long as wide, the outer angle a little 

 less acute; coarser punctures not evident on the elytra; first ventral segment 

 carinate at middle, the carina beginning on the intercoxal process and not quite 

 reaching the apical margin. Length 4.75-6.25 mm. 



California, Anderson Springs, Lake County (Fuchs) ; Los Ange- 

 les County (Coquillet) ; Claremont (Baker). 



One example from each of the above localities. Judging from 

 the small eyes, which do not vary appreciably in the three speci-
