Head smooth, with a deepangulated impression ending behind in fovee ; 
occiput with a shallow fovea ; transverse line of prothorax very deep ; 
elytra very convex, sutural stria faint....20.2 .. 5... 11. americanum. 
Norn.—In 7. foveicolle, globiferum, inpunctatum and californicum there 
are two fine short impressed lines at the base of the dorsal surface of the 
abdomen, as in many species of Bryavis. 
29. Euplectus debilis, n. sp.—Elongate, somewhat depressed, 
brown ; antenne, palpi and legs paler. Head with a deep, acutely angulate 
impression ending behind in two fovez ; occiput elevated, not impressed. 
Prothorax with large lateral basal foveze, an angulated posterior impres- 
sion, and a deep, interrupted dorsal channel ; the basal part extending to 
the transverse impression, the discoidal part attaining neither the impres- 
sion nor the apicalmargin. Elytra with deep sutural stria, and short dorsal 
one ; basal foveze not large. Length .6 mm.; .026 inch. 
Tampa, May, one specimen. Not larger than EF. pumilus, 
but quite distinct by the more elongate and depressed form, 
and by the dorsal channel of the prothorax less deep, and 
more completely interrupted. 
30. Euplectus tenuis, n. sp.—Elongate, less depressed, brown ; 
elytra darker, antenne, palpi, and legs paler. Head with a deep, arcuated 
impression ending behind in fove ; occiput convex, very feebly impressed. 
Prothorax with large, lateral fovex, and an angulated posterior impression, 
dorsal channel very fine, not extending to the apical margin, sub-inter- 
rupted near the transverse impression. Elytra with deep sutural stria ; 
dorsal stria fine, extending to the middle. Length .7 mm.; .028 inch. 
Capron, May, one specimen, Nearly related to H. debilis, 
but more pubescent, with the front more convex, the impres- 
sion curved rather than angulated, and the dorsal line of 
the prothorax finer. The following species, though not be- 
longing to the same district, is closely allied: 
36. Euplectus imteger, n. sp.—EHlongate, dark brown, slightly pu- 
bescent, -antenne, palpi, and legs paler. Head with two large fovez, not 
connected by an impression ; front convex, but not prominent. Prothorax
