Micratopus insularis n. sp. 
So similar to the preceding as not to require a full de- 
scription. Differs (from parviceps) in being smaller, 
slightly more convex, with relatively smaller prothorax and 
larger head with larger, more prominent eyes. Length 
± 1 % mm. 
Holotype (United States National Museum) and 1 para- 
type (Museum of Comparative Zoology no. 19506) from San 
Juan, Puerto Rico, Aug. 11, 1933, A. S. Mills, at light. 
42. Diplochaetus rutilus (Chev.) . 
43. Perileptus (s. s.) columbus n. sp. (PI. 5, fig. 4.) 
Form and proportions as figured; depressed; entirely 
rufo-testaceous ; upper surface with fine, short pubescence 
which does not conceal the underlying surface. Head 
across eyes by measurement barely narrower than pro- 
thorax, but appearing slightly wider; temples parallel for 
a short distance behind eyes before being constricted ; front 
shining, obsoletely punctate ; antennae slender, median 
joints about three times as long as wide; mentum toothed, 
tooth subtruncate apically. Prothorax cordate; base more 
than two-thirds (by measurement) as wide as widest part; 
sides sinuate about one-sixth from base, thence nearly 
straight to the regular, right or slightly obtuse basal angles ; 
lateral margin moderate, entire, crenate near base; disk 
rather finely and closely punctate, basal transverse line very 
deep, anterior line less deep, median longitudinal line well 
impressed. Elytra also rather closely and finely punctate; 
sutural stria distinct except at base, one or two next striae 
vaguely indicated; three discal punctures on position of 
third stria on each elytron, about a fifth from base, just be- 
hind middle, and about a tenth from apex respectively. Male 
with first two joints of front tarsus somewhat dilated. 
Length 2% -2% mm. 
Holotype $ (Museum of Comparative Zoology no. 19507) 
and 9 paratypes (2 in collection Jeannel), including both 
sexes, from Soledad (near Cienfuegos) Cuba, Oct. 27 & 28,
