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 ristilus (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*4-2% 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,
