"Taurus, pi-es du Kuleg-Boghaz, dans les Fontaines d'eau vive." 



This should probably be placed in the genus Deronectes, as it is stated to belong to the " opatrinus 

 group."— D. S.

" OvaHs, ^ix elongatus, depressus ; capite testaceo ; prothorace testaceo, antice angustissime infuscato, 

 postice maculis duabus griseis \lx coiispicuis notato, subtiliter jiunctato, in disco fere Isevi ; elyti-is sat 

 fortiter punctatis, griseo-testaceis, ad scutellum et suturam obscurioribus, maculis duabus in sutura latis 

 confusisque vix iiotatis, striga suturali nuUa ; prothoracis elytrisque strigis curtis, ad basLa fere contiguis ; 

 subtus i-ufo-testaceus, pedibus concoloribus. Long. 1^ m.m."

" Ovatus, latus, depressus, crebre punctatus, flavus ; elytris flavis, nigro-notatis. Long. corp. If lin., 

 lat. 4-1 lin." 



" Ovate, broad, somewhat depressed, attenuated towards the apex, flavous : head short, broad ; on either 

 side within the margins of the eyes is a narrow depression ; the surface is finely punctate : thoi-ax broad, 

 rounded in front, the sides marginate, in front and near the base transversely subdepressed ; the surface 

 is finely punctate, flavous, the anteiior and posterior margins being narrowly and evenly fuscous black : 

 elytra thickly and finely punctate, flavous, with two, three or four longitudinal markings of fuscous 

 black : in one of the two examples before me the colour is rather fuscous black, with two intennipted and 

 irregular medial bauds of flavous. The great dissimilarity of pattern between these two examples 

 plainly shows that the sjjecies is subject to much variety ; it may readily be lUstinguished from all others 

 by its sectional characters, the absence of any thoracic fovea, the angle formed by the sides of the elytra 

 and the thorax, and by its smaller size."

This may perhaps be a species of Chostonectes. — D. S.

"Long. Si m.m., lat. 2 m.m. Breviter ovalis, leviter convexus, parce pubescens, subnitidulus, nigro- 

 piceus ; ore antennarum basi, maculis elytrorum pedibusque testaceo-rufis. Caput minutissime punctatum. 

 Thorax capite vix duplo latior, latitudine tertia parte paulo longior, antice valde angustatus, a latere 

 rotundatus, supra scutellum triangulariter lobatus, crebre minutissime punctatus, sulco transverso, grosse 

 punctato antice instiiictus. Elytra basi thoracis basi latitudine ac jiroxime ampliora, medio parum 

 latiora, apice conjunctim rotuudata, densissime minutissime punctulata, basi utrinque testaceo-maculata ; 

 scilicet litura loiigitudinali ad scutellum, macula oblonga in medio, altera arcuata ad humerum interdum
