SPONDYLID^: 217 



female of gravidula but with two broad basal furrows on the occiput, 

 separated by one-half the width of the latter and slightly diverging 

 from the base, not extending quite to the posterior line of the eyes 

 and with the elytral punctures nearly twice as numerous as in any 

 other example; the occipital furrows may be a malformation, in 

 which case there would be insufficient ground for naming it. The 

 other specimen is a large stout female, nearly black in color through- 

 out, otherwise nearly like the female of ampliceps, except that the 

 head is a little smaller, the prothorax more transverse and the 

 elytra longer. I have placed it with brunnea for the present. The 

 above measurements exclude the mandible?. 



The following is probably different from glabra Degeer, with 

 which Mr. Bates may have placed his material from a near-by 

 locality: 



*Parandra obsolescens n. sp. Stout, parallel, moderately convex, 

 highly polished, impunctateand pale brownish-testaceous in color through- 

 out; eyes well developed, moderately convex; prothorax two-thirds wider 

 than long, the sides straight and parallel, with fane reflexed margin before 

 the middle to the obtuse apical angles, then broadly, circularly rounding, 

 with wider concave margin around the basal angles to the median trunca- 

 ture, which is a little more than half the total width; elytra parallel, 

 circularly rounded conjointly at apex, as wide as the prothorax and three- 

 fourths longer than wide; carina of the hind tibiae near the inner edge. 

 Length (9 ) 26.0 mm.; width 8.2 mm. Costa Rica (Chiriqui). 



The antennae are of somewhat different structure from those of 

 the three American species described above, the depressed sensitive 

 grooves not being narrow and well separated but broader, shallower 

 and coming together on the under edge of the joints along a fine 

 and entire carina. Under careful observation with good optical 

 power, the remains of punctuation may be traced throughout the 

 body in the f Drm of excessively fine, sparse and feeble points. The 

 coarse deep longitudinal groove at each side of the front, does not 

 quite attain the apical margin at the base of the mandibles. From 

 what is said of glabra by Bates, it would seem that it is always 

 punctate, for he speaks of varying degrees of punctuation; the 

 present form is impunctate within the ordinary meaning of that 

 term, but at the same time obsolescens may prove to be no better 

 than a subspecies.
