Larvarium: a tube or case made by a larva as a shelter or retreat. 

 Larvatae: masked; applied to coarctate and obtect pupae. 

 Larvina: a maggot: a dipterous larva without distinct head or legs. 

 Larvule: applied to early stages of Ephemerid larvse when they appear to 



have no developed respiratory, circulatory or nervous systems. 

 Lashed: eyes that have a more or less complete fringe of stiff hairs or bristles 



at the orbits. 

 Lasureus: a very dark blue [French blue with some black]. 

 Laterad: toward the side and away from the median line. 

 Lateral: relating, pertaining or attached to the side. 

 Lateral areas: in Hymenoptera ; on the metanotum, the three spaces between 



the median and lateral long carina : the upper is the external or first lateral 



basal area ; the second is the external or central lateral area ; the third is 



the middle, internal, apical or third lateral area. 

 Lateral bristles: in Dif>tera; situated at or near the lateral margins of the 



abdominal segments. 

 Lateral carinae: in Ortlwptera ; on the head, extend downward from the front 



margin of the eyes : on prothorax extend along each lateral margin of the 



dorsum. 

 Lateral foveolae: in Orthoptera : foveate depressions on the margins of the 



vertex near the front border of the eye. 

 Lateral line: in caterpillars is at the margin of the dorsum between sub- 

 dorsal and supra-stigmatal line. 

 Lateral lobe: of the labium in Odonata, corresponds to the paraglossa with 



palpiger and palpus (Gerstsecker) or, more probably, to the palpus alone 

 (Butler). 

 Lateral lobes: the deflexed portions of pronotum that cover the sides of pro- 



thora.x in many Orthoptera: in certain Hymenoptera, lie on each side of 



the parapsidal furrows of mesoscutum and = scapulae. 

 Lateral longitudinal area: of Hymenoptera, extends between the median and 



pleural carinae of metanotum. 

 Lateral ridge: in slug caterpillars, extends longitudinally along the lateral 



series of abdominal tubercles. 

 Lateral scale: one of the lateral processes of the ovipositor in Cynipidcr, lying 



within and below the anal scale. 

 Lateral space: in slug caterpillars is the area on each side of the body be- 

 tween the subdorsal and lateral ridges. 

 Lateral sutures : of the thorax in Odonata, are situated on the sides of thorax, 



the first separating the metepisternum from the mesepimeron ; the second 



separating the metepisternum from the metepimeron ; the first more or less 



obsolete in the Anisoptera. 

 Lateral tubercle: lateral on thoracic and abdominal segments of caterpillars: 



it is 3 of the abdomen, 2a of thorax: constant (Dyar). 

 Latericeous: = lateritius ; q. v. 

 Lateritius: yellowish-red; yellowish brick color [pale clay yellow with a little 



red]. 

 Laterodorsal: the point of junction of dorsum and pleurum.
