ALTICINAE FROM THE WEST INDIES — BLAKE 27 



basal callosities and transverse depression below them, surface coarsely 

 and confusedly punctate. Body beneath with prostemum extending 

 down widely between anterior coxae, hind femora enlarged, hind tibiae 

 not channelled but rounded, spur at end, claws appendiculate. 



Type of genus, Sidfaya polutima, new species. 



Remarks. — The beetles are somewhat similar in shape to those of 

 the genus Heikertingerella but are not so smoothly convex, the elytra 

 having basal callosities and a transverse depression. In addition, the 

 strong, even coarse, punctation is unlike any found in Heikertingerella. 



The genus is named in memory of Dr. Sidney Fay Blake. This 

 name also has an interesting parallel in Greek: aidapos (sidaros=iron) 

 and (f)aco (phao= shining). 



Sidfaya polutima, new species 



Figure 21 



About 2 mm. in length, ovate, convex, shining, with dense and 

 somewhat confused punctation, dark piceous black with tibiae and 

 tarsi yellowish brown and basal seven joints of antennae pale yellow, 

 four terminal joints thickened and dark, hind femora enlarged, hind 

 tibiae rounded with small spur at end, claws appendiculate. 



Head with interocular space half width of head, smoothly rounded, 

 pohshed and impunctate over occiput, a groove on each side extending 

 from fovea near eye down to frontal tubercles with several punctures 

 along it, frontal tubercles small and distinct, interantennal area 

 sUghtly produced, flat, with no definite carina and somewhat declivous below. 

 Antennae reaching below humeri, the two basal joints swollen, joints 

 three to six pale yellow, subequal, joints seven to eleven gradually 

 becoming wider and last four joints piceous. Prothorax approximately 

 twice as wide as long with sinuate, almost angulate, lateral margin, 

 a broad oblique angle anteriorly ending in prominent tooth at lower 

 end and another tooth at basal angle, moderately convex, without 

 depressions, surface shining black, with strong punctation. Scutellimi 

 dark. Elytra moderately convex, with small humeral prominences 

 and short intrahumeral depression, distinct depression below basal 

 callosities, surface shiny with strong and not too dense punctation 

 becoming somewhat less distinct at apex, punctation with tendency 

 to being striate but not actually so, epipleura vanishing at apical angle. 

 Body beneath having prosternum extending down widely between 

 anterior coxae and closing anterior coxal cavities. Hind femora much 

 enlarged, hind tibiae entire, rounded, a spur at end, claws appendiculate. 

 Length 1.8-2 mm.; width 1.1 mm.
