This species was first described from a single male as belong- 
ing to Dynopsylla, but some characters were noted in which the 
species did not conform to the generic type. Subsequently many 
other specimens of this species have come to hand and among 
them females. The genitalia of the female at once show a 
marked difference not only from Dynopsylla but from most other 
genera. This species, therefore, is designated the type of a 
new genus, which appears to be related to other genera of Car- 
sidarinae. Since the first description did not include the female 
and was somewhat inadequate in a few other respects, a more 
detailed specific description is given herewith to replace the 
other.

Length of body, 2.7 millimeters ; length of forewing, 5 ; greatest 
width, 2.3. General color light brown with darker brown streaks 
on thoracic dorsum or the color may be dark brown with lighter 
streaks; antennae with apical third or half of segments 3 to 8 
and all of 9 and 10 black. Body surface more or less covered 
with white flocculent excretion. Insect large and robust. 
Head about as broad as prothorax, but mesothorax consider- 
ably broader, not much defiexed, cleft in front. Vertex a little 
more than half as long as broad, deeply concave, the median 
suture prominent, and the two halves nearly quadrate, the outer 
anterior corner acute and upstanding, giving the appearance of 
a horn (somewhat as in Dynopsylla) ; anterior margin of ver- 
tex somewhat emarginate, the protruding gense at base of an- 
tennae much emphasizing this emargination. Anterior ocellus 
in front at base of cleft; frons visible as a small and narrow 
sclerite between gense and below front ocellus. Gense very large, 
protruding in front to form antennal bases, beneath the head 
and just in front of labrum produced into pair of very small 
wartlike cones. Labrum not large ; beak about as long as third 
antennal segment. Antennae moderately long and slender, not 
as long as body but usually as long as head and thorax or a 
little longer. 
Thorax very large, well arched and broad, sparsely hairy. 
Pronotum large ; mesonotum very large ; metanotum with a pair 
of short blunt horns or epiphyses caudad. Legs long and large ; 
hind tibia with spur at base and several long fingerlike spines 
at apex ; tarsi long. Forewings large and long, narrowly rounded 
at apex, transparent, with four small brown spots along poste-
