In addition to the described pair, three female paratypes, bear- 
ing the same data, are before us. 
Xestoblatta poecila new specie.s (Plate IX, figure 18.) 
The present species is the most strikingly colored form of the 
genus Xestoblalta which we have seen. The coloration, and par- 
ticularly that of the pronotum, is distinctive. The species is 
aiipareutly more nearly related to A", nyctihoroides (Rehn) than 
to the other species at hand. Discovery of the male sex is 
awaited with interest. 
Type . — 9 : Villavicencio, Intendencia del ]\Ieta, Colombia. 
I'ilevation, 1400 feet. December, 1918. (From A. Maria). 
[Hebard ('ollection. Type no. 545.] 
Size medium for the genus, form robust. Interoeular s])ace (1.2 mm.) 
four-hfths as wide as that betw'een the antennal soekets. Oeellar areas 
weakly defined, but the convexity at their inner margins stronger than is 
usual in the genus. Pronotum as characteristic of Xestobhitla. 
4'egmiua and wings reaching beyond apex of abdomen a distance ecpial 
to the length of the caudal tarsal joints, with venation as characteristic of 
the genus. Wings with (five) complete ami (four) incomplete branches of 
the ulnar vein. Abdomen with fourth, fifth ami sixth tergites with latero- 
caudal angles acute-angulate produceil caudad. 
Su])ra-anal i)late half as long as ])roximal width, triangidarly produced 
Ix'tween the cerci, with lateral margins rather decidedly concave and ai)ex 
rounded. 8ubgenital plate little produced, with surface broadly convex: 
free margin evenly and rather broadly convex, showing weak flattening of 
this convexity beneath the cerei, with margin distad thickened, so as to 
<'ause an ui)per rim, but not briefly curled u])ward and inward. 
Limbs as characteristic of the genus.**' 
*■* For the females the allotype is given first, then the extremes in the para- 
types.

**' Described, 4’rans. .\ni. Ent. Soc., xui, p. o7(), ( It) 16). The pulvilli and 
arolia have' not been described for Xv.stohldttd. The thri'e [)roxiinal tarsal 
joints are (>ach supplied veiitrad with a bi.seriate row of minute spinesand 
distad with a large pulvillus, as broad as long with apex rounded, the short 
tourth joint with veidral surface fully (xa-upied by a similar jadvillus. .Arolia 
well develo|)ed between the simpl(>, .symmetrical tar.^al claws.
