NEW DASCYLLIDAE. 
BY CHARLES SCHAEFFER, BROOKLYN, N. Y. 
Lachnodactyla texana new species 
Piceous brown, antennae and legs paler, form of Ptilodactyla serricoUis, but 
slightly more robust and the vestiture coarser. Head granulate-punctate; eyes 
large, separated by slightly less than their own width; antennae long and slen- 
der, joints four to ten each with a ramus, which is much longer than the joint to 
which it is attacherl. Prothora.x twice as wide at base as long, sides compressed 
anteriorly, arcuately converging behind, hind angles acute and slightly refle.xed; 
base bisinuate, denticulate; surface convex, feebly depressed behind, not very 
densely granulate-jtunctate. Scutellum moderate, sub-cordiform, not impressed at 
base but with four denticles. Elytra elongate, very little wider than the thorax at 
base, humeri rounded; punctate-striate, striae distinct, intervals finely and sparsely 
punctate. Apex of fifth ventral segment feebly emarginate. Length 6 mm., width 
2.75 mm. 
Esperanza Ranch, Brownsville, Texas, May 30, one male. 
Differs from the Central American inoyiticola by the head being granulate-punc- 
tate, scutellum without notch in front and with only two teeth on each side of 
base, the elytral striae distinct and finely but not rugo.sely punctate. Some of these 
characters separate it also from parvMCUfum. 
Lachnodactyla arizonica new species. 
Ferruginous-brown, closely resembling Pfilodacfyla serricoUis, but slightly more 
elongate. Head granulate-punctate; eyes rather small, widely sejjarated by more 
than their own width; antennae .slender, ramus of each joint as long, or very 
slightly longer, than the joint itself, last joint elongate-oval, slightly wider than 
the penultimate. Thorax at base twice as wide as long, bisinuate, denticulate; 
sides arcuately narrowing to apex; hind angles acute and feebly reflexed; surface 
convex and feebly depressed behind. Scutellum moderate, feebly cordate, median 
impression deep in front, but base without denticles on each side. Elytra elongate, 
slightly broader than the thorax at base, obsoletely punctate-striate, intervals flat, 
feebly rugose and finely punctate. Fifth ventral segment at apex feebly emargi- 
nate. Length 5 mm., width 2.5 mm.
