790 Coleopterological Notices, VI. 



arcuate; apex ciicularly rounded; humeri rounded and rallier narrowly ex- 

 posed at base; disk convex, tlie intra liunieral impression xn-y feeble and 

 basal; punctures not very coarse but distinct, rather sparse, becoming gradu- 

 ally obsolete at apex. Legs moderate in length, somewliat slender, the hind 

 femora not at all inflated. Length 1.65 mm. ; Avidth 0.(5 mm. 



Florida (Tampa,). Hubbard and Schwarz. 



The fourth ventral, in the single type before me, is about one- 

 half longer than the third and circularly rounded. This species 

 differs from quei^cicola in its broader and more oval form and 

 much larger eyes, in addition to the characters of the table. 



PSEIDARIOTUS n. gen. 



The rather minute species separated nnder this name have a 

 short obese and convex form of body, polished elytra, and a ves- 

 titure wliich is suberect and composed of hairs Avliicli dilfer dis- 

 tinctly in length and w^hich are confusedly intermingled. The 

 head is only very slightly wider than tlie prothorax, the e^'es 

 somewhat large, convex, extending to within an extremely short 

 distance of the base, rather finely' faceted and with a small but 

 distinct anterior notch ; thej^ are distinctly and rather densely 

 pilose. Epistoraal suture distinct. Last joint of the maxillary 

 palpi moderately large, right-angled, that of the hilnal unusually 

 developed, short but extremely transverse, with the subtruncate 

 apex concave and spongy, differing noticeably in form from any 

 of the previous genera, but resembling somewhat that of San- 

 dytes. Antenna' slender, gradually and feebly incrassate, mode- 

 rate in length, i)ilose. Prothorax feebly constricted at the sides 

 of the apex, the disk somewhat uneven, transversely and slightly 

 tumid behind the middle and tumid near the sides at apical and 

 basal third. Scutellum broadly triangular, subtruncate at tip. 

 Basal segment of the abdomen distinctly shorter than the remain- 

 der, Avith the dividing suture only slightly indicated near the sides 

 of the body, the succeeding segments subequal among themselves. 

 The elytra are black, ornamented with pale spots. 



The two species known to me may be distinguished as fol- 

 lows : — 



I'ronotum opaque, posterior pale spots of the elytra situated just behind the 



middle 1. iiotatus 



Pronotum polished ; posterior pale spots at apical fourth 2. amicus 



Nothing is known concerning the sexual characters, which are 

 probably very slight.
