86 Mr. G. C. Champion’s Notes on 
transverse ; elytra oblong, parallel, the epipleura extremely narrow ; 
anterior coxae small, placed near the base of the prosternum, 
separated by a thin lamella, the acetabula open; middle coxae 
somewhat widely separated; tibiae obliquely truncated at tip; 
tarsi 4-jointed in both sexes, 1-3 clothed with a few long hairs 
beneath, 1 as long as 2 and 3 united, 3 small, free, 4 elongate; body 
elongate, glabrous, metallic. 
Type, S. deceptor. 
The insect forming the type of this genus was rejected by 
myself from the Pythidae in 1889, when dealing with the 
Central American representatives of that family of the 
Heteromerous Coleoptera. It has exactly the facies of a 
Salpingid (such as Sosthenes), and if excluded from the 
Pythidae, on account of its tarsal structure, the genus 
must be placed in Cucujidae, near Phloeostichus and 
Hymaea, which have the tarsi 5-, 5-, 4-jointed in the male. 
It is probable, however, that the Pythidae will have to be 
placed, sooner or later, in the Clavicorn series, near Cucu- 
jidae, Salpingomimus clearly showing that the tarsal 
formula alone is a character upon which too much depend- 
ence has been placed by systematists. 
*Salpingomimus deceptor, n. sp. (Plate III, figs. 8, g; 
8a, maxilla and maxillary palpus.) 
Moderately elongate, shining, glabrous, aeneous or greenish- 
aeneous, the mouth-parts, base of antennae, and tarsi ferruginous. 
Head closely punctate, the transverse groove behind the epistoma 
very deep; antennae moderately long, a little shorter in 9, joint 1 
very stout, 7 and 8 transverse, 9-11 much wider and stouter, 9 and 10 
strongly transverse, 11 acuminate-ovate. Thorax convex, oval, as 
long as broad, narrower than the head with the eyes, feebly margined 
at the base only, closely punctate. Elytra oblong, as wide as the 
thorax, depressed on the disc below the base; seriato-punctate, the 
seriate punctures becoming almost obsolete towards the apex and 
more confusedly arranged at the base, the interstices usually with 
a few scattered punctures. Beneath densely, the metasternum more 
sparsely, punctate, the abdomen almost smooth. Tibiae widened on 
the inner side from about the middle to the apex in g, more feebly 
soin 3. ‘Tarsi slender, joints 1 and 2 slightly thickened. 
Length 2;;-3 mm. (d 9.)
