106 CORYLOPHID. 
tacula coxarum late complexis. Mesosternum magnum ; episternis longis; epimeris longis, trigonalibus, 
ad coxas extensis. Metasternum modicum, corporis lateribus haud attingens, margine posteriore inter 
coxas recta; episternis latis et longis. Venter segmentis sex compositus, basali praelongo, apicali obtuso. 
Pedes sat longi, simplices ; tarsis brevibus, robustis, articulis quatuor compositis, apicali ceteris et longiore 
et tenuiore ; unguibus gracilibus, leviter curvatis. Cove: anteriores haud prominentes, per carinam divisa ; 
intermedi longius, distantes ; posteriores sat remotee, breviter pyriformes. 
Body elongate, obconical. Head wholly exserted, produced anteriorly, convex above and below, the mouth 
prominent ; antenne inserted considerably in front of the eyes; eyes prominent. Thorax small, with 
the anterior margin entire, straight, but not excavated behind the head; basal margin faintly arcuate, 
with the angles obtuse. Scutellwm large, short and broad, obtusely triangular. lytra elongate, 
attenuated posteriorly, separately rounded at the apex. Abdomen moderately exposed. Antenne not 
geniculated, 10-jointed—1 long, robust, recurved, 2 half as long as and much more slender than 1, 3-7 
more slender than 2, transverse, gradually incrassated, 8-10 forming a much incrassate subfoliate club, 
with the apical joint the largest and rounded. Paris of the mouth not dissected, but apparently of a 
normal type. Prosternwm rather large, elevated between the coxee, and prolonged and dilated behind 
them ; episterna minute; epimera rather large, broadly enclosing the coxal cavities ; coxal cavities oval 
and oblique. Mesosternum large; episterna long and narrow; epimera long, subtriangular, extending to 
the coxal cavities ; coxal cavities rounded and rather distant. Metasternum moderate, not reaching to the 
sides of the body; posterior margin between the coxe straight; episterna broad and long; epimera 
narrow, concealed by the elytra ; coxal cavities remote from each other, and moderately distant from the 
sides of the body. Venter composed of six segments—1 very long, 2-6 equal in length to each other, 
the apical segment obtusely rounded, simple. Legs: anterior with the trochanters small, triangular ; 
femora depressed, long and broad ; tibiee rather shorter, much dilated towards the apex; tarsi short and 
robust, 4-jointed, with the three basal joints nearly equal, and the apical joint longer and more slender ; 
claws slender and faintly curved ; intermediate similar to the anterior, but rather longer ; posterior with 
the interior angle of the trochanter much prolonged, and the femora robust and very long ; tibize long, 
simple, dilated towards the apex; tarsi similar to the anterior, but rather longer. Cox@: anterior 
rounded, not prominent, separated by the elevated portion of the prosternum ; intermediate rounded, 
rather distant; posterior remote from each other, rather short, pear-shaped, not reaching to the sides of 
the body. 
Ectinocephalus would seem more properly to form a distinct ‘Tribe’; but for reasons 
already stated I have placed it among the ‘Saclina,’ with which it agrees in the elon- 
vate form of the body. 
The genus contains a single species from Guatemala.

Head rather small, convex, produced in front; eyes very large and prominent; antenne robust, bright yellow. 
Thoraw moderate; almost circularly rounded in front, with the margin entire and slightly reflexed, 
minutely and closely tuberculate or alutaceous, with an impressed line at the base; basal margin almost 
straight, with the angles nearly rectangular. Scutellum small and rounded. lytra rather broader and 
nearly twice as long as the head and thorax, widest at the shoulders, attenuated posteriorly, deeply punc- 
tured, with the interstices shining, a deeply impressed line on each side of the suture ; sides slightly
