Head : front with two slightly impressed, widely separated 
sulci slightly converging anteriorly; antennse short, second 
joint shorter than third, middle joints hardly' longer than 
wide ; mentum without foraminiform punctures, with blunt 
tooth in emargination. Prothorax slightly more than a 
half wider than long (by measurement) ; sides rounded an- 
teriorly, slightly and very gradually sinuate posteriorly; 
posterior angles acutely but very minutely denticulate, 
costae within angles short and not conspicuous ; lateral mar- 
gins evenly explanate, wider than in Tachys ( Tachyta ) 
inornata (Say), less wide than in T. flavicauda; basal 
transverse impression deep, anterior faint, median line 
rather deep. Elytra only slightly depressed; sutural stria 
deep and entire, recurved as usual ; other striae all more or 
less abbreviated but all visible basally, either as impressed 
faintly punctate lines or (externally) as series of small 
punctures ; fourth stria with fixed punctures near base and 
about apical third. Two basal joints of male front tarsus 
dilated and with anterior apical angles slightly produced. 
Length = j-2 1 /2 mm. 
Haiti, W. M. Mann: Holotype (Museum of Comparative 
Zoology no. 19499) and 3 paratypes from Grande Riviere; 
2 paratypes from St. Marc. 
This species is apparently not closely related to any of 
those known from North or Central America; its color pat- 
tern is unique. It is intermediate between the so-called 
genera Tachyta and Tachymenis as used by Casey (Me- 
moirs 8, 1918, p. 3).
